3.2 Installation Procedures

The following sections detail the installation procedures for a Cisco 6260 with a POTS splitter configuration.

3.2.1 Measure Rack Space

For the rack to remain stable, you must install your Cisco 6260 system from the bottom to the top of the rack.

Before you install any of the chassis, measure the total rack space required to install your system. The required rack space depends on the number of Cisco 6260 chassis and third-party POTS splitters that you plan to use. The number of chassis increases if you plan to install a subtended network.

Note See "Preparing for Installation," to determine the total rack space you need for your configuration.

Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

—This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

—When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

—If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back.

Warning Never attempt to lift the chassis with the handles on the power supplies, fan trays, or the switching modules. These handles are not designed to support the weight of the chassis. Using them to lift or support the chassis can result in severe damage to the equipment and serious bodily injury.

If you plan to expand your system to include more chassis in the future, allow space in the rack for additions, keeping in mind the weight distribution and stability of the rack.

3.2.2 Install the Third-Party POTS Splitter

The third-party POTS splitter is installed directly below the Cisco 6260 chassis in the rack.

Refer to the appropriate vendor documentation for installation procedures for the third-party POTS splitter.

3.2.3 Attach Ear Brackets to the Cisco 6260

Verify that the ear brackets on the sides of the chassis are in the proper configuration to fit the rack, and if necessary, reinstall them. Ear brackets can be installed in two ways, as shown in Figure 3-1:

Figure 3-1: Mounting Options for Ear Brackets

For Cisco 6260 installation in an ETSI 600-mm (23- inch) rack, attach the L-shaped ear brackets so that the short sides are against the chassis wall and the long sides protrude from the chassis.

For Cisco 6260 installation in a 19-inch rack, attach the ear brackets so that the long side of each L is against the chassis wall and the short side protrudes from the chassis.

Note The ear brackets are installed in the factory for a 19-inch rack configuration.

3.2.4 Install the Cisco 6260 Chassis

Complete the following steps to install the Cisco 6260 chassis.

Step 1 Connect a grounding strap to the ESD grounding jack that is located on the top right of the front of the Cisco 6260 chassis.

Step 2 Using a Phillips-head screwdriver, attach the two mounting aids to the rack above the third-party POTS splitter. Use two screws for each mounting aid, as shown in Figure 3-2. The lower edge of the mounting aid lines up with the bottom of the chassis.

Figure 3-2: Screw the Mounting Aids to the Rack

Step 3 Carefully lift the chassis from underneath and rest it on the mounting aids, as shown in Figure 3-3.

Figure 3-3: Mounting Aids Support the Chassis During Installation

Step 4 Push the chassis back into the rack.

Step 5 Using a Phillips-head screwdriver, screw the ear brackets on the chassis to the rack. Use two screws at the top of each ear bracket and two at the bottom (four screws per bracket). For stability, make sure you use at least one round hole at each end of each bracket (the ear brackets have both round and oval holes).

Step 6 Repeat Step 1 through Step 5 for each Cisco 6260 chassis that you are installing.

3.2.5 Install Blank Faceplates

Blank faceplates should occupy any empty slots in the Cisco 6260 chassis. Blank faceplate installation is similar to line card installation.

Complete the following steps to install blank faceplates in the Cisco 6260:

Step 1 Connect a grounding strap to the ESD grounding jack that is located on the top right of the front of the Cisco 6260 chassis.

Step 2 Vertically align the blank faceplate edge with the guides at the top and bottom of the slot.

Step 3 Lift up on the ejector tab and gently apply pressure to the bottom of the faceplate while pushing the blank faceplate into the slot.

Step 4 Push on the faceplate to fully seat the blank faceplate.

Step 5 Press down on the ejector tab to secure the faceplate.

3.2.6 Ground the Cisco 6260

Complete the following steps to connect the grounding lug on the Cisco 6260.

Warning When you are installing the unit, the ground connection must always be made first and disconnected last.

Warning Before connecting or disconnecting ground or power wires to the chassis, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. Use a voltmeter to test for 0 (zero) voltage at the power terminals on the chassis.

Step 1 Ensure that power in the direct current (DC) circuit is off.

Step 2 Remove all paint or oxidation from the rack at the point of the grounding connection.

Step 3 Measure enough wire to connect the Cisco 6260 to the rack. Use 10 American Wire Gauge (AWG) green or green with yellow stripes wire to ground the Cisco 6260 chassis.

Note Use only as much wire as is necessary to make the connection.

Step 4 Use a wire stripping tool to remove the covering from the end of the grounding wire. The manufacturer of the grounding lug might have a specific recommendation about the length of wire to be stripped.

Step 5 Insert the stripped end of the grounding wire into the open end of the grounding lug. Be careful not to leave any wire strands outside the lug.

Step 6 Use the crimping tool to compress the lug onto the wire.

Step 7 To verify the quality of the crimp, inspect it and tug gently on the wire.

Step 8 Locate the three grounding holes on the Cisco 6260 side panel. (See Figure 3-4.)

Step 9 Match the holes in the grounding lug to the appropriately spaced pair of grounding holes on the side of the chassis. Use the top two holes for a 5/8-inch lug, as shown in Figure 3-4. Use the bottom two holes for a 3/4-inch lug.

Figure 3-4: System Ground Connection

Step 10 Insert the screws through the holes in the lug and the chassis. Use the Phillips-head screwdriver to tighten the screws and secure the grounding lug firmly to the chassis.

Step 11 Prepare the other end of the grounding wire and connect it to an appropriate grounding point in your site.

Step 12 Repeat Step 1 through Step 11 for each Cisco 6260 chassis, as necessary.

3.2.7 Ground the Third-Party POTS Splitter

Refer to the appropriate vendor documentation for grounding procedures for the third-party POTS splitter.

Note Do not ground the components in a rack by chaining them together.

3.2.8 Connect the Cisco 6260 to the Third-Party POTS Splitter

Refer to the appropriate vendor documentation for cabling procedures for the third-party POTS splitter.

3.2.9 Connect the Third-Party POTS Splitter to the MDF or to the Cross Connect

Refer to the appropriate vendor documentation for procedures for connecting the POTS splitter to the MDF or to the cross connect.

3.2.10 Attach Cisco 6260 Power Connections

External power is supplied to the system as -48 VDC from the central office (CO) power source or rectifier to the fuse and alarm panel. Power is fed from the fuse and alarm panel to receptacles in terminal blocks located on the power entry modules (PEMs) installed in the Cisco 6260 chassis.

Connect the power connections on each PEM to separate power sources to achieve full power redundancy. If you do not require power redundancy, use the terminals on a single PEM, or connect both PEMs to a single power source.

Complete these instructions to connect the Cisco 6260 system to a -48 VDC power source. Ground the chassis before you attempt this procedure, as described in the "Ground the Cisco 6260" section.

Note See "Preparing for Installation," for the calculation tables that you need to determine the minimum power requirements for your system.

Caution To prevent the system from powering up, do not install the fuses at this time. If the fuses are already installed in the fuse and alarm panel, remove them. You can replace the fuses after the system is installed and connected.

Follow these instructions to attach the power connections to the Cisco 6260 PEM:

Step 1 Verify that power in the DC circuit is off.

Warning Before connecting or disconnecting ground or power wires to the chassis, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF (0) position, and tape the switch handle of the circuit breaker in the OFF (0) position. Use a voltmeter to test for 0 (zero) voltage at the power terminals on the chassis.

Step 2 Connect a grounding strap to the ESD grounding jack that is located on the top right of the front of the Cisco 6260 chassis.

Step 3 Prepare the wire for the Cisco 6260 power and grounding connections, as follows:

a. Measure enough wire (6 to 10 AWG multistranded copper wire) to connect each of the PEM power connections to the fuse and alarm panel, as well as enough to connect the grounding receptacle on the PEM terminal block to the grounding connection at the DC power source.

b. Cut the ends of the power and ground wires so that the ends are straight, not slanted.

c. Measure 0.43 inch (11 mm) up from the end of each power and ground wire and place a mark at that point. These are the wire ends that will be connected to the Cisco 6260.

d. Use the wire stripping tool to remove 0.43 inch (11 mm) of the covering from both ends of each wire. Trim the ends of the covering so that they are straight, as shown in Figure 3-5, not slanted.

Figure 3-5: Strip and Square Off Power and Ground Wires

Warning Remove the covering from exactly the specified length of each power wire. If you strip too much of the covering, exposed wire protruding from the terminal block will create an electrical hazard. If you strip too little of the covering, the wire may not make a good contact with the terminal, or it may not be held securely in place in the terminal block.

Step 4 Use a flat-head screwdriver to turn all three screws on the terminal block counterclockwise to open the terminal connectors: + (positive), - (negative), and ground. This step ensures that the correct opening is presented for the wires, as shown in Figure 3-6.

Figure 3-6: Positioning the Power and Ground Terminals to Accept Wires

Step 5 Insert the end of the grounding wire into the grounding receptacle, which is the bottom receptacle in the terminal block on the PEM (see Figure 3-7). The stripped part of the wire must be fully inserted into the terminal block so that no bare wire is exposed.

Step 6 Ensure that no wire strands are left outside the connector.

Step 7 Using the screwdriver and a clockwise motion, tighten the ground screw in the terminal block. Gently tug on the wire to ensure that it is firmly in place.

Figure 3-7: Insert Grounding Wire into Grounding Receptacle

Step 8 Make sure that the other end of the grounding wire is connected to ground at the DC power source.

Step 9 If you are connecting two power sources to the Cisco 6260 system, repeat Step 2 through Step 8 for the second PEM.

Warning Only a DC power source that is isolated from the AC main power source with reinforced insulation, and that complies with the other safety extra-low voltage (SELV) requirements in UL1950, CSA 950 3rd Edition, EN 60950, and IEC950, can be connected to a Cisco 6260 system. This requirement ensures that in a catastrophic power source fault condition, hazardous voltages are not present on power terminals and connectors.

Step 10 After connecting the battery return wire to the external power source, insert the other end into the receptacle labeled + (positive) on the terminal block of the first PEM, as shown in Figure 3-8. The stripped part of the wire must be fully inserted so that no bare wire is exposed. Using the screwdriver and a clockwise motion, tighten the terminal screw. Gently tug on the wire to ensure that it is firmly in place.

Figure 3-8: Connecting Power to the Terminal Block

Step 11 After connecting the power lead to the external -48V power source, insert the other end of the wire into the receptacle labeled - (negative) on the terminal block of the first PEM, as shown in Figure 3-8. The stripped part of the wire must be fully inserted so that no bare wire is exposed. Using the screwdriver and a clockwise motion, tighten the terminal screw. Gently tug on the wire to ensure that it is firmly in place.

Step 12 If you are connecting a second power source, repeat Step 10 and Step 11 to wire it to the second PEM.

Note Be sure that the chassis is connected to earth ground as described in the "Ground the Cisco 6260" section on page 3-7. The Cisco 6260 requires two or three ground connections, one to the side of the chassis and one to each PEM.

Step 13 Repeat Step 2 through Step 12 for each Cisco 6260 chassis, as necessary.

Warning Do not yet power up the system.

3.2.11 Connect the Alarm and BITS Clock Contacts

Note Connecting the alarm and BITS clock contacts are optional procedures.

Complete the following steps to connect the external alarm and BITS clock contacts:

Step 1 Connect the external alarm device and BITS clock to the wire-wrap pins on the I/O module at the top of the chassis.

a. Measure one strand of twisted-pair wire (24 AWG industry standard T1/E1 cable) long enough to connect to the appropriate pin.

: See Figure 3-9 for a close-up of the pinouts that are located on the I/O module. For pinout descriptions, see the "E1 I/O Module RJ-48c Connectors" section.

Figure 3-9: I/O Module Wire-Wrap Pins Close-up

b. Use a wire stripper to remove the casing from both ends of the wire.

c. Use a wire-wrapping tool to attach the wire to the appropriate pin.

d. Use a wire-wrapping tool to attach the other end of the wire that is used in Step 1c to either the BITS clock source or alarm relay contact.

e. Repeat this step to wire-wrap all the necessary pins.

Note The BITS pins on Cisco 6260 I/O cards are slot specific. BITS_A pins are assigned to chassis slot 11 and BITS_B pins are assigned to chassis slot 10. Each BITS clock input is independent and terminated at 100 ohms.

Step 2 Reboot the system to reassociate the system MAC address.

Step 3 Repeat Step 1 and Step 2 for each Cisco 6260 chassis, as necessary.

3.2.12 Apply Power

Complete the following steps to apply power to the Cisco 6260 system:

Step 1 Apply power to the system with one of the following methods:

Install the fuses in the fuse and alarm panel.
Reinsert the fuses in the fuse and alarm panel, if you removed them in the "Attach Cisco 6260 Power Connections" section.
Turn on the breakers in the fuse and alarm panel.

Caution If the power connections are improperly made and power is applied while the cards are installed, the cards and chassis could be damaged.

Step 2 Verify that the power connections are made correctly, as described in the "Attach Cisco 6260 Power Connections" section.

Step 3 Check the polarity of the -48 VDC connections to each chassis by attaching a voltmeter with the minus lead on -48RTN and the plus lead on -48V_A or -48V_B. Ensure that the meter reads between -40.5 VDC and -75 VDC. If your voltmeter shows a positive voltage, check to ensure that the meter leads are not reversed. If the voltmeter shows a negative voltage that is out of the -40.5 VDC to -75 VDC range, check the power supply for failure or check for a blown fuse in the fuse and alarm panel.

Step 4 Turn on power to the DC circuit.

Step 5 Use a voltmeter to check the voltage at the terminal block. Connect the voltmeter positive contact to the positive (+) terminal on the Cisco 6260 terminal block. Connect the voltmeter negative contact to the negative (-) terminal on the Cisco 6260 terminal block. If the power is wired correctly, you will see a reading of -48V on the voltmeter.

Step 6 At the front of the chassis, switch the circuit breakers on both PEMs to the ON (1) position.

Step 7 Repeat Step 1 through Step 6 for each Cisco 6260 chassis, as necessary.

3.2.13 Verify Fan Tray Operation

Verify that the fan trays are operational by checking the fan tray LEDs, located on the PEMs that are installed beneath the fan trays. If the LED is

Green—The fan is operational.
Not green—The fan is not operational and the fan tray may be in alarm mode. See "Troubleshooting," for corrective action.

Caution The fans in both fan trays must run continuously. The system might suffer thermal damage if the fans in either tray stop for more than 5 minutes.

3.2.14 Connect the Cisco 6260 System to the Network

3.2.19 Complete Initial Configuration

When you turn on the Cisco 6260 for the first time, an interactive dialog called the System Configuration Dialog appears in a window on the console screen. The System Configuration Dialog guides you through the initial configuration process. (You can run the dialog at any time by entering the setup command in privileged EXEC mode.)

When you complete the dialog, the system displays the configuration command script that you have created. It then offers you three options:

[0] Go to the IOS command prompt without saving this config.
[1] Return back to the setup without saving this config.
[2] Save this configuration to nvram and exit.

If you enter 2, the configuration is saved and used. If you answer 0 or 1, the configuration you created is not saved. Enter 1 if you wish to discard the configuration and restart the System Configuration Dialog.

3.2.19.1 Before You Begin

Complete these steps before you run the System Configuration Dialog:

Step 1 Determine the IP address for the Ethernet interface.

Step 2 If you plan to configure in-band management, determine the IP address for the ATM interface that will be used for in-band management (ATM0/1 or ATM0/2).

Step 3 Find out what the password strategy is for your environment. The System Configuration Dialog window prompts you for three passwords, plus an SNMP community string. The three required password types are enable secret, enable, and virtual terminal.

Step 4 Choose a name for the Cisco 6260. (This step is optional.)

3.2.19.2 Using the System Configuration Dialog

The System Configuration Dialog offers two configuration options: basic management setup and extended setup.

Choose basic management setup if you want to use the System Configuration Dialog to configure the passwords and the Ethernet interface only, and then use the management station or the command line interface (CLI) to configure the remaining Cisco 6260 interfaces.
Choose extended setup if you want to use the System Configuration Dialog to configure all of the Cisco 6260 interfaces.

An example of each type of setup follows the "Interface Numbering" section.

3.2.19.2.1 Interface Numbering

The System Configuration Dialog window and the CLI use the following interface numbering scheme:

Interfaces whose names begin with "ATM0" (ATM0/0, ATM0/1, and so forth) are NI-2 card network trunk interfaces. ATM0/0 is the ATM switch interface with the processor (sometimes referred to as the ASP interface, for ATM switch/processor). There is no need to configure ATM0/0 unless you plan to use in-band management. ATM0/1 is the trunk port. ATM0/2 and ATM0/3 (if present) are subtending interfaces.
Interfaces whose names begin with "ATM1" through "ATM32" are line card interfaces. (NI-2 slots, ATM10 and ATM11, are omitted.)

: For line card interfaces, the number before the slash indicates the slot number. The number after the slash indicates the interface or port number. For example, ATM6/4 is slot 6, port 4.

Ethernet0/0 is the interface for the LAN that connects the Cisco 6260 to its management system.

3.2.19.2.2 Basic Management Setup Example

This is the basic management setup example:

         --- System Configuration Dialog ---
 
Would you like to enter the initial configuration dialog? [yes/no]: y

At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
 
Basic management setup configures only enough connectivity
for management of the system, extended setup will ask you
to configure each interface on the system
 
Would you like to enter basic management setup? [yes/no]: y

 
Configuring global parameters:
 
  Enter host name [DSLAM]:
 
  The enable secret is a password used to protect access to
  privileged EXEC and configuration modes. This password, after
  entered, becomes encrypted in the configuration.
  Enter enable secret: beansoup

 
  The enable password is used when you do not specify an
  enable secret password, with some older software versions, and
  some boot images.
  Enter enable password: beansoup

% Please choose a password that is different from the enable secret
  Enter enable password: lab1

 
  The virtual terminal password is used to protect
  access to the router over a network interface.
  Enter virtual terminal password: 
% No defaulting allowed
  Enter virtual terminal password: lab

 
  Configure SNMP Network Management? [yes]: y

    Community string [public]: 
 
Current interface summary
 
Any interface listed with OK? value "NO" does not have a valid configuration
 
Interface             IP-Address      OK? Method Status                Protocol
ATM0/0                unassigned      NO  unset  up                    up      
Ethernet0/0           unassigned      NO  unset  up                    up      
ATM0/1                unassigned      NO  unset  down                  down    
ATM0/2                unassigned      NO  unset  down                  down    
 
Enter interface name used to connect to the
management network from the above interface summary: Ethernet0/0

 
Configuring interface Ethernet0/0:
  Configure IP on this interface? [yes]: y

    IP address for this interface: 172.27.144.141

    Subnet mask for this interface [255.255.0.0] : 
    Class B network is 172.27.0.0, 16 subnet bits; mask is /16
 
The following configuration command script was created:
