This chapter explains the procedures for installing the access server. Installation involves the following tasks:
1. Connecting cables to the AC power supply (AC installs only)
1. Rack-mounting the AC power supply (AC installs only)
2. Rack-mounting the dial shelf
3. Replacing the blower assembly, DC PEMs, and dial shelf cards or controller cards
4. Connecting power inputs to the DC PEMs
5. Mounting the AC power safety cover (AC installs only)
6. Rack-mounting the router shelf
7. Connecting all remaining cable connections
Estimated time to install the access server hardware is between 2 and 3 hours.
Note If you are installing the optional AC-input power shelf, refer to the"Connecting to an AC Power Source" section.
This chapter assumes that you are installing the access server manually. If you have access to a forklift or hydraulic equipment during the installation, you can omit certain steps, which are specified later in this chapter.
If your site has access to an AC power source only, you need to install the optional AC-input power shelf (DS58-PWR-2AC) to convert to DC-input power for the dial shelf.
AC-input power is accepted using a separate, self-contained AC-input power shelf, which converts AC-input power to DC-output for use by the DC-powered dial shelf. The AC-input is supplied by two AC power cables (CAB-DS-AC=, other options available), converted to -48V DC-output power for the dial shelf PEMs using two AC-to-DC power cables (DS5800-CAB-ACDC=) supplied by Cisco.
The AC-input power shelf is an optional component of the Cisco AS5800 and is used to convert AC-input power into DC-output power for the DC-powered Cisco 5814 dial shelf. The AC-input power shelf contains two AC-input power supplies.
This section explains how to attach the power cables and rack-mount the AC-input power shelf. For detailed cabling specification tables, refer to "Cisco AS5800 Specifications."
You need the following tools and parts to rack-mount the power shelf:
To connect the power cables and power up the system, proceed to the following section "Connecting the AC Power Cables."
It is possible to mount the cables on the AC power supply after it has been rack-mounted, but given the limited space in and around many equipment racks, we recommend that you mount the cables before rack-mounting the AC power supply. Figure 3-1 shows cables mounted on a standard AC power supply, but the process is the same for the enhanced power supply. For a picture of the rear of the enhanced power supply, see Figure 1-17. To mount the AC power supply cables:
Step 2 Secure the double ring lug to both threaded ground posts with a hex nut on each stud.
Step 3 Attach two red DC-interconnect power-cable ring lugs to the terminal stud labeled BUS + on the AC power shelf chassis rear. (See Figure 3-1.)
Step 4 Secure the ring lugs to the threaded stud with a hex nut.
Step 5 Attach two black DC-interconnect power-cable ring lugs to the terminal stud labeled BUS - on the AC power shelf chassis rear. (Refer to Figure 3-1.)
Step 6 Secure the ring lugs to the threaded terminal stud with a hex nut.
Step 7 Attach the monitor cable DB-25 plug to the DB-25 receptacle on the rear of the AC-input power shelf. (See Figure 3-1.) Tighten the jackscrews.
You install the power shelf in the rack by securing the permanent mounting flanges to two posts or mounting strips in the rack using the slotted mounting screws provided. Because the mounting flanges support the weight of the entire power shelf, be sure to use at least two slotted screws per mounting flange.
Note You need to leave 1.75 in. (4.45 cm) between the power shelf and the dial shelf that you will install directly above it.
To remove a standard power supply, follow these steps:
Step 2 Lift the metal spring-clip in the center of the ejector lever to release the lock. (The power supplies are secured by self-locking ejector levers. (See Figure 3-2.)
Step 3 Apply downward pressure to the ejector lever to disconnect the power supply from the power backplane.
Step 4 Grasp the power supply handle and pull the power supply halfway out of the bay. Then with your other hand under the power supply to support it, pull the power supply completely out of the bay.
Step 5 Repeat Step 1 through Step 4 for the other power supply.
To remove a power supply for the enhanced AC-input power shelf, follow these steps:
Step 2 Twist the thumbscrew located in the ejector lever to unlock the power supply (See Figure 3-2.)
Step 3 Lift the ejector lever to disconnect the power supply from the power backplane.
Step 4 Grasp the power supply handle and pull the power supply halfway out of the bay. Then with your other hand under the power supply to support it, pull the power supply completely out of the bay.
Step 5 Repeat Step 1 through Step 4 for the other power supply.
To install the power shelf in the rack, follow these steps:
Step 2 Position the power shelf in front of the rack. To prevent injury, avoid sudden twists or moves.
Step 3 Lift and slide the power shelf into the rack, pushing it back until the front mounting flanges meet the mounting strips or posts on both sides of the equipment rack.
Step 4 Position the power shelf so that the holes in the mounting flanges are aligned to those in the mounting strips, while keeping the mounting flanges flush against the posts or mounting strips.
Step 5 Insert the 10-32 x 3/8-inch slotted screws (two screws per side at a minimum) through the power shelf mounting flange and into the mounting strip. Tighten all screws using a 1/4-inch flat blade screwdriver.
Step 6 Replace the power supplies.
(a). Slide the power supply into the power supply bay. Push the power supply fully into the power shelf until the front is flush against the power shelf frame. To prevent damage to the backplane connector, do not jam the power supply into the bay.
(b). Push the self-locking ejector lever upward until the metal spring-clip locks into place (listen for the click). (See Figure 3-2 or Figure 3-3.)
Figure 3-4 illustrates the standard AC-input power shelf installed in a 4-post rack.
One person can not install the dial shelf chassis in the rack unassisted. Two or preferably three people will be needed.
To secure the rack-mount brackets to the posts or mounting strips in the rack, you must use the slotted mounting screws provided. Because the brackets support the entire weight of the chassis, be sure to use at least two slotted screws per bracket.
Be sure you have the dial shelf prepped as described in the previous chapter before installing it in the rack. To install the dial shelf chassis in the rack, complete the following steps:
![]() |
Tip To prevent injury, review the safety precautions in the "Safety Recommendations" section before installing the dial shelf in the rack. |
Step 2 Attach one support bracket to each front post or mounting strip using the provided slotted screws and a 1/4-in., flat-blade screwdriver. Ensure that the support brackets are level. (See Figure 3-5 and Figure 3-7.)
Note Because the brackets support the weight of the entire chassis, be sure to use at least two slotted screws per bracket. These brackets also ensure that the required space between the dial shelf and the power supply is available.
Step 3 Position the dial shelf chassis in front of the rack.
Step 4 Lift and slide the dial shelf chassis into the rack, resting it on the two support brackets. Push it back until the forward brackets or chassis mounting flanges meet the mounting strips or posts on both sides of the equipment rack. When the chassis is slid back all the way, keep one or two people holding the chassis in place using the handles, or gripping the chassis where the DC PEMs belong.
Note The brackets support the chassis until you complete the installation. Removing the brackets is optional. If you leave the brackets installed, they can be used as spacers between the dial shelf and the optional AC-input power shelf.
Step 5 While two people hold the dial shelf steady, a third person should insert the 10-32 x 3/8-in. slotted screws (2 screws per bracket) through the brackets (or chassis mounting flange) and into the mounting strip. Install two screws near the bottom of the flanges first, then install more screws above them, spaced evenly along the flange. Tighten all the screws using a 1/4-in. flat-blade screwdriver.
To complete the dial shelf rack installation, mount the rear set of brackets to the chassis. Proceed to the following section "Mounting the Rear Brackets."
This section explains how to mount the rear brackets for telco and 4-post rack installations.
For a telco rack-mount installation, mount the rear bracket as follows:
Step 2 Thread two M5 x 10-mm Phillips flathead screws through the bracket and into the side of the chassis.
Step 3 Using a No. 2 Phillips screwdriver, tighten the screws.
Step 4 Repeat Step 1 through Step 3 to mount the rear bracket on the other side of the chassis.
Step 5 Insert the 10-32 x 3/8-in. slotted screws (2 screws per bracket) through the brackets and into the equipment rack-mounting strip.
Step 6 Tighten all the screws using a 1/4-in. flat-blade screwdriver.
Figure 3-6 shows a dial shelf installed in a telco rack. The bracket positions labeled a, b, and c correspond to Figure 2-8, positions a, b, and c.
This completes the dial shelf rack-mounting procedures for a telco rack. Proceed to the section "Replacing the Dial Shelf Components."
For a 4-post rack-mount installation, mount the optional rear brackets to the sides of the chassis as follows:
Step 2 Thread two M5 x 10-mm Phillips flathead screws through the bracket and into the side of the chassis.
Step 3 Using a No. 2 Phillips screwdriver, tighten the screws.
Step 4 Repeat Step 1 through Step 3 to mount the rear bracket on the other side of the chassis.
Step 5 Position the rear equipment rack-mounting strips flush with the dial shelf chassis rear rack-mounting brackets and secure the strips in the equipment rack.
Step 6 Insert the 10-32 x 3/8-in. slotted screws (2 screws per bracket) through the brackets and into the equipment rack-mounting strip.
Step 7 Tighten the screws using a 1/4-in. flat-blade screwdriver.
This completes the dial shelf rack-mounting procedures for a 4-post rack. Proceed to the following section "Replacing the Dial Shelf Components."
This section contains instructions for replacing the dial shelf components.
Replace the blower module in the dial shelf as follows:
Step 2 Align the blower assembly with the chassis opening and slide the blower assembly into the dial shelf chassis.
Step 3 Push the blower assembly all the way into the dial shelf chassis until the connector on the rear of the blower assembly is fully seated in the chassis.
Step 4 Tighten the two captive thumbscrews on the blower assembly front panel.
To reinstall the PEMs, complete the following steps. (Refer to Figure 3-9 to locate the PEMs in the dial shelf.)
Step 2 Slide the PEM into the power supply bay until it is fully seated and connected to the backplane connectors.
Step 3 Using a 1/4-inch flat-blade screwdriver, tighten the captive screws on the PEM front panel.
Step 4 Plug the alarm cables into the bell alarm terminal block. (See Figure 3-9.)
Step 5 Repeat Step 1 to Step 4 for the other PEM.
This completes the procedure for replacing a PEM in the dial shelf.
Replace the trunk cards, modem cards, and dial shelf controller cards in the chassis as follows:
![]() | TimeSaver Your dial shelf arrived with trunk cards, modem cards, and dial shelf controller cards installed in the proper slots. You can refer to the notes you made before removing the cards (as described in the "Removing Dial Shelf Cards and Dial Shelf Controller Cards" section) when replacing cards in the dial shelf chassis. |
If you did not note the original card configuration, replace the cards in the dial shelf slots, which are numbered from left to right, as follows:
Step 2 Carefully align the card carrier guides with the top and bottom grooves in the slot. Avoid touching the circuitry or any connector pins.
Step 3 Slide the carrier into the slot until the ejector levers make contact with the chassis frame. (See Figure 3-10.)
Step 4 Seat the card in the backplane by pushing the card firmly until the ejector levers fold in toward the trunk card front panel and the front panel is flush with the chassis frame.
Step 5 Using a No. 2 Phillips screwdriver, tighten the panel fasteners on the top and bottom of the card front panel. This prevents the card from becoming partially dislodged from the backplane and ensures proper EMI shielding.
Step 6 Repeat Step 3 through Step 5 for all remaining cards you want to install.
Step 7 Install a blank filler card (DS58-BLANK=) in all empty card slots to keep the chassis dust-free and to maintain proper airflow.
Once the dial shelf has been rack-mounted and all components have been reinstalled into the dial shelf, DC power connections from a DC source or AC-input power shelf can be connected to the dial shelf. The monitor connection from an AC-input power shelf should also be connected at this stage. The following sections assume the use of the optional AC-input power shelf. If your installation will use a DC power source, see the "Connecting to a DC Power Source" section.
You need to connect all cables between the AC-input power shelf and the dial shelf before you connect the power shelf to your AC power source. You also need to install the provided electrical connection safety cover at the rear of the power shelf before you power up the system. For detailed cabling specification tables, refer to "Cisco AS5800 Specifications."
For detailed cabling specification information, refer to "Cisco AS5800 Specifications." To attach the ground cable between the AC-input power shelf and the dial shelf, complete the following steps:
Step 2 Align the second ring lug hole with the second pemnut in the underside of the dial shelf chassis and thread a screw through the hole.
Step 3 Using a No. 2 Phillips screwdriver, tighten both screws.
This completes the ground cable installation.
For detailed cabling specification information, refer to "Cisco AS5800 Specifications." To connect the DC interconnect power cables, complete the following steps:
Step 2 Loosen the screws in each PEM DC terminal block, located on the back of the dial shelf. (See Figure 3-13.)
Step 3 Fit the exposed wire end of one red insulated cable into the DC terminal block labeled -48V RTN on each PEM and securely tighten the terminal block connector screws. (See Figure 3-13.)
Step 4 Fit the exposed wire end of the black insulated cable into the DC terminal block labeled -48V on each PEM and securely tighten the terminal block connector screws. Repeat for the other PEM. (See Figure 3-13)
Note You must attach the red DC cables to the stud labeled BUS + on the AC-input power shelf and connect the other end to a -48V RTN terminal on each PEM. You must attach the black DC cables to the stud labeled BUS - and connect the other end to a -48V terminal on each PEM. If the two DC conductors entering the PEM terminal block are reversed, a yellow warning LED on the PEM lights to indicate a miswire. No damage will occur; however, you must power OFF the power at the source and reverse the connections.
This completes the DC power cabling installation. You must now connect the monitor cable from the AC-input power shelf to the dial shelf filter module.
For detailed cabling specification information, refer to "Cisco AS5800 Specifications." To connect the monitor cable, complete the following steps:
Step 2 Tighten the jackscrews.
This completes the monitor cable installation. You must now connect the AC-input power cords.
For detailed cabling specification information, refer to "Cisco AS5800 Specifications." To connect the AC power cords, complete the following steps:
Step 2 Plug each AC power cord into an AC receptacle on the AC-input power shelf rear. (See Figure 3-16, or Figure 3-17 for an enhanced power shelf.)
Step 3 If you are using an enhanced power shelf, connect the opposite end of each power cord to a 220VAC power source. If you are using a standard power shelf, install the safety cover before connecting to a power source.
This completes the AC power cord installation.
For safety reasons, you must install the metal safety cover that shipped with your standard AC-input power shelf before you power up the system. The safety cover shields the power connections from possible short circuit and protects you from electrical shock.
To install the safety cover, follow these steps:
Step 2 Slide the safety cover into place and attach the front of the cover to the dial shelf with the screws provided.
Step 3 Connect the opposite end of each power cord to a 220VAC power source.
The following sections are for installations using a direct DC power source, without an AC-input power shelf.
The Cisco 5814 dial shelf ships with a double ground lug attached to two pemnuts in the upper left corner on the rear of the dial shelf chassis. For detailed cabling specification information, refer to "Cisco AS5800 Specifications." To ground the dial shelf, follow these steps:
Step 2 Attach the double ground lug to your own 6-gauge ground wire.
Step 3 Using the screws you removed, fasten the ground lug to the dial shelf chassis.
If your site has access to a DC power source, you need to provide your own DC power cables. In the United States you need to use 6 AWG stranded or solid copper wire; elsewhere use 16 mm2 solid or 10 mm2 stranded copper wire.
Complete the following cabling instructions:
Step 2 Strip the DC power cable of its outer insulation to expose about 1/2-inch of copper wires.
Step 3 Connect the power cable stripped wires to the DC terminal block on the PEM and securely tighten the terminal block connector screws. (See Figure 3-20.)
Step 4 Connect the other end of your DC power cables to your DC power source.
Step 5 Repeat Step 1 through Step 4 to connect your DC power cables to the second PEM.
Note If the two DC conductors entering the PEM terminal block are reversed, a red warning LED on the PEM goes on to indicate a miswire. No damage will occur; however, you must power OFF the power at the source and reverse the connections.
This completes the procedure for installing the dial shelf in a rack. You are now ready to install the Cisco 7206 router shelf in the equipment rack.
The router shelf is intended to be rack-mounted above the dial shelf in the same rack; however, you can rack-mount the router shelf in an adjacent rack. The interconnect cable supplied by Cisco, which provides the physical connection between the router shelf and the dial shelf, is available in 6-ft or 20-ft lengths.
There is no clearance requirement for mounting the router shelf directly above the dial shelf. Use the rack-mounting brackets and cable-management kit that shipped with the Cisco 7206 router shelf to install the router in the rack.
Note To install the Cisco 7206 router shelf, refer to the Cisco 7206 Installation and Configuration Guide that shipped with your Cisco 7206 router shelf. After you complete the router shelf installation, you are ready to connect the cables. Proceed to the following section "Connecting the Dial Shelf to the Router Shelf."
Note It is possible to use two routers in a split dial shelf configuration with a single 5814 dial shelf. Install the second router shelf above the first.
The Cisco 7206 router shelf contains a dial shelf interconnect port adapter with a single RJ-45 receptacle, which is used to connect the router shelf to the Cisco 5814 dial shelf. The interconnect port adapter installs in any 7206 router shelf port adapter slot and connects directly to the Cisco 5814 dial shelf controller card using a single full-duplex cable.
The cable used for this connection is available only from Cisco Systems. It is customized with shielding to decrease electromagnetic interference (EMI) emissions, and jackscrews to secure the connection. You must use this specially designed cable, which shipped with your interconnect port adapter, to connect the dial shelf to the router shelf. For detailed cabling specification information, refer to "Cisco AS5800 Specifications." If the cable was not shipped, contact CCO as described in the"Cisco Connection Online" section.
Figure 3-21 shows the dial shelf interconnect cable with jackscrew connectors.
Figure 3-22 shows the RJ-45 receptacle on the dial shelf interconnect port adapter.
To connect the dial shelf interconnect cable, follow these steps:
Step 2 Tighten the jackscrews on either side of the connector.
Step 3 Attach the other end of the cable to the port labeled "Dial Shelf Interconnect" on the dial shelf controller card front panel.
Step 4 Tighten the jackscrews on either side of the connector.
Step 5 If you will be using a split dial shelf configuration, repeat Step 1 through Step 4, connecting the second dial shelf controller card to the second router shelf.
Egress connections to LANs and WANs are made through the host Cisco 7206 router shelf. Using port adapters, the router shelf supports interfaces such as FDDI, HSSI, Fast Ethernet, and ATM. Each interface port adapter is shipped with separate configuration instructions and cable information.
For example, if you install a Fast Ethernet port adapter in the Cisco 7206 router shelf, refer to the configuration note PA-FE-TX and PA-FE-FX Fast Ethernet 100BASE-T Port Adapter Installation and Configuration (Part Number 78-2659-xx) that shipped with your Fast Ethernet port adapter. This document is also available in the Documentation CD-ROM and on Cisco Connection Online (CCO).
The trunk card provides 12 RJ-45 receptacles for channelized E1 or T1 lines, or BNC connectors for T3 trunk lines. To connect T1 or E1 trunk lines, follow these steps:
Step 2 Attach the network end of your CT1 cable to your external network, or for CE1 cabling, attach the network end of your CE1 cable to your network termination (NT1) device.
Step 3 Repeat Steps 1 and Step 2 for as many as 11 more T1 or E1 cables.
For more information about trunk cables and trunk cards, refer to the Cisco AS5800 Universal Access Server Dial Shelf Card Guide.
To connect the T3 lines, follow these steps:
Step 2 Attach the network end of your CT3 cables to your external network.
A DCE-mode console port and a DTE-mode auxiliary port are located on the router shelf I/O controller. The console port is a DB-25 receptacle for connecting a data terminal, which you use to run the initial setup script and bring up the Cisco AS5800. The auxiliary port is a DB-25 plug for connecting a modem or other DCE device (such as a CSU/DSU or other router) to the router shelf. (See Figure 3-26.)
Note Both console and auxiliary ports are asynchronous serial ports; any device connected to these ports must be capable of asynchronous transmission.
Before connecting a terminal to the console port, configure the terminal to match the router console port as follows: 9600 baud, 8 data bits, no parity, 2 stop bits (9600 8N2). You need an EIA/TIA-232 DCE console cable to connect the terminal to the console port. After you establish normal router operation, you can disconnect the terminal. While both the router shelf and the dial shelf have console ports, functions for both shelves are available from the router console port.
You must supply your own interface cable between the auxiliary port and the equipment you are connecting. Refer to the Cisco 7206 Installation and Configuration Guide that shipped with your router shelf for console and auxiliary port pinouts.
This completes the procedures for installing and cabling your Cisco AS5800. To start the access server, proceed to "Powering On the Cisco AS5800 and Observing Initial Startup Conditions."
