This chapter covers the following elements of installing the MGX 8240 Private Line Service Gateway:
Install the MGX 8240 in a clean, dry, well-ventilated area (see Table 1-2). Verify that a -48 VDC (approximately 40 Amps) source is close to where the MGX 8240 will be mounted. Also make sure there is an accessible site ground to connect to the equipment rack, or follow local wiring practices.
Table 1-1 shows the dimensions of an unmounted MGX 8240 unit.
| Dimension | Value |
Depth |
|
| 18.43 in |
| 22.5 in |
Width | 21.5 in |
Height | 33.25 in (19 RU) |
Weight |
|
| 100 lbs |
| 125 lbs |
| 220 lbs |
Shelf wattage (fully loaded) | 1500 watts |
The MGX 8240 should be mounted in a standard 23-inch relay rack. Two MGX 8240 systems can fit in a single rack.
Leave space in front of and behind the MGX 8240 for installation, maintenance, and wiring. You will need at least 2.5 ft (0.75 m) clearance at the front of the rack and at least 2.0 ft (0.60 m) clearance at the rear of the rack.
The unit vents vertically. Air is pulled in from the front and sides, and exits on the top and sides. Leave at least 5 ft between the top of the MGX 8240 and the shelf above it. The air filter fits at an angle in the lower section of the chassis (see Figure 1-3).
Certain site requirements (temperature and humidity, altitude, system grounding, and ESD/EMI precautions) must be met to ensure that the MGX 8240 unit functions well.
The MGX 8240 is intended for indoor use.Table 1-2 lists the necessary shipping, storage, and operating temperatures
| Condition | Specification |
|---|---|
Shipping temperature | -40 to +66 degrees C (-40 to +150.8 degrees F) |
Storage temperature | -30 to +50 degrees C (-22 to +122 degrees F) |
Operating temperature | 0 to 40 degrees C (32 to 104 degrees F) |
Relative humidity | 5% to 90% non-condensing Note: When the MGX 8240 is mounted with the Common Interface Module, the humidity must stay between 20% and 80%. |
Altitude | Between 60 m (200 ft) and 4000 m (13,000 ft) above sea level |
The MGX 8240 supports chassis ground (protective earth ground) for optimum performance as well as personal safety. All accessible surfaces that may become energized under a fault condition are connected to the ground.
Chassis ground points must be connected to the appropriate building ground points according to local wiring practices. Ground wires require a minimum diameter of 1.85 mm or 6 AWG (American Wire Gauge). If local codes allow grounding to the equipment rack only, ground wires are not required; use ground straps.
 |
Caution Before attempting to handle any electronic parts, put on an antistatic wrist strap (supplied) and connect it to the grounded equipment. The MGX 8240 has electro-static discharge (ESD) jacks in front and back. On the front panel, the ESD jack is at the left near the bottom of the far left PSM. On the back panel, the ESD jack is at the left near the bottom of the far left I/O Module. |
The MGX 8240 has been tested against all relevant standards of electromagnetic interference (EMI). However, Cisco recommends that users avoid placing the rack close to very strong EMI sources such as elevators, air-conditioners, photocopiers, and fax machines.

To install the MGX 8240, you will need the following:
|
Caution An antistatic wrist strap must be worn during installation to prevent electrostatic damage to the MGX 8240. |
|
Caution Three people are needed to lift the chassis. If three people are not available, use a hand lift. |
Unpack the box(es) and check contents against the shipping list (see Appendix B). Save the packaging.
If the box has been damaged or if some parts are missing or defective, call 800-553-2447 and the package carrier to report the damage. Obtain a Returned Material Authorization (RMA) number and include the RMA number on the label. Return the unit in original packaging.
The following sections describe the procedures required to mount the MGX 8240 and bring it on line.
|
Caution Before attempting to handle electronic parts, put on a grounded antistatic wrist strap. |
Step 1 Use the bolt-positioning template provided by Cisco to plan position of bolts. You may find it helpful to install some bolts from the back to the front before lifting the chassis into place.
Position the MGX 8240 at the top of the equipment rack or otherwise as planned by engineers. Cisco recommends that installers have three people available to lift the chassis, and have a fourth person to bolt the chassis into place. If three people are not available, use a hand lift.
Step 2 Connect the chassis ground wire to the signal ground lug on the rear of the switch.
 |
Note No more than two MGX 8240s can be mounted in a 7-foot rack. |
This step is only for persons who need to retrofit the MGX 8240. If you have received the retrofit shipping kit and need to retrofit your MGX 8240 switch, use the information provided in Appendix C, "Retrofit MGX 8240 Installation Addendum."
The MGX 8240 requires -42 VDC to -56 VDC power at approximately 40 Amps for a fully loaded shelf.
|
Note Make sure power is turned off. |
Step 1 Connect the DC power (Cisco recommends number #6 AWG Solid Wire).
Step 2 The MGX 8240 supports dual DC feeds. Determine if you want two separate dual feeds or one.
Step 3 Connect one end from the DC power into the MGX 8240 connector block as shown below.
| Cable Type | Connector Type | Purpose |
|---|---|---|
Power | #6 AWG lug | Supplies -48 VDC power to the MGX 8240 |
The MGX 8240 has 15 full-size slots and 2 half-size slots. An IMC fits into each of the two half-size slots. Redundancy is optional, if you want redundancy, you may install two IMC cards (one primary and one backup).
The IMC I/O Panel has an RJ45 connector for the Shelf Ethernet Interface, an RJ11 connector for the Shelf RS232 serial interface, pin connectors for the 4 alarm relay contacts, and 2 BITS inputs.
The Redundant Switch Out LED changes from yellow to green when the IMC becomes primary, and from green to yellow when the IMC becomes secondary.
The RS232 connector is for factory use only.
The Reset button, recessed about 1.5 inches behind the faceplate, does a hard reset of the card.
The IMC takes the place of the Common Interface Module (CIM). The CIMs on older chassis are being replaced with IMCs. Release 2.2 C2X MGX 8240 chassis comes with IMC card(s) installed (one is required, two are optional for redundancy).
IMC cards are hot-swappable. Replacing a CIM unit with an IMC card requires several external changes, including changing BITS clock connections and moving Ethernet and RS232 connectors from the old CEMI/O card to the new IMCI/O card. See Figure 1-6
|
Note If you are changing from a CIM to an IMC card on a chassis with traffic, you will need to refer to the IMC Upgrade Procedure, available from TAC. |
Whenever switching over to standby IMC, all the active telnet and ftp sessions need to be reinitialed. The current ftp session would get terminated with "netout: Socket operation on non-socket" error for ftp and all telnet sessions would hang.
The IMC card requires information on the following parameters:
After FDOS, users can access the IMC card through all the same means that access the PSM cards: V-CLI, VT-100, telnet, etc. However, to do FDOS, it is necessary to use the serial port, connecting to a dumb terminal or PC.
To perform FDOS on the IMC card, follow the steps below:
Step 1 In a terminal window, at the login prompt, enter the following command:
sysadminAt the password prompt, enter the following command:
sysadminStep 2 At the IMCCMDR> prompt, type <?> or help to show options.
Step 3 You will see a screen containing eight commands: change, menus, show, oper, set, exit, connect, and remoteshell. For FDOS, you will use the menu command. Enter the following command:
IMCCMDR> menu |
Note In IMCCMDR, it is not necessary to type the whole command, only the first letter(s) unique to the commands. For instance, for the menu command, you can type m. |
This first screen will have four options:
1. Node Setup

Step 17 To reboot, use <Esc> to return to the Main menu. Use the arrow key to highlight the Exit option, and press <Enter>.
After FDOS, the IMC's Ready LED will turn green, signalling that NAT is possible.
The secondary IMC automatically derives FDOS configuration from the primary. The user does not have to perform FDOS on the secondary card.
To install the I/O modules on the rear of the chassis, perform the following steps:
Step 1 Put the CIMI/O into slot 1, on the far right. Slide it in until you feel a slight resistance, then put your thumbs on the thumb levers and push the module gently into place.
Step 2 Attach the remaining 15 I/O modules into their respective slots.
The MGX 8240 provides two types of network connections (refer to Table 1-4):
1. DS3 Channelized Access with IOM or OC3 channelized access with IOO.
2. OC3 Single-Mode Intermediate Reach fiber unchannelized for network.
The DS3 channelized access typically connects to Digital Cross-Connect Systems (DCS) or M13 multiplexers via a DSX-3 cross-connect panel. The DS3 connectors are located on each rear I/0 panel (slots 2-16).
Perform the following steps to make the connection:
Step 1 Connect the BNC on the DS3 access Tx port to the Rx of far end equipment. Use the lower cable tray.
Step 2 Connect the BNC on the Rx port to the Tx port.
Step 3 Repeat Steps 1 and 2 for each of the remaining DS3 connections.

|
Warning Improper insertion of card can damage the midplane. |
Step 2 Place the remaining 14 PSMs in the same manner.
|
Note The FACTORY RS232 connector is for manufacturing purposes only—do not use it. |
The MGX 8240 is connected to the IMC IO Ethernet port.
The MGX 8240 has two BITS inputs labeled Ref CLK A and Ref CLK B. Both inputs are identical; if you are installing only one BITS source, it does not matter which input you use. The connections are characterized by three wires labeled T (Tip), R (Ring), and S (Signal Ground).
The BITS Clock Source should be a DS1, B8ZS signal from Stratum 3 or higher clock source. The clock source is terminated at the unit.
|
Note Figure 1-9 shows the cabling for a DS3; cabling for the OC3 differs (see Figure 1-4). |
To start the MGX 8240, perform the following steps:
Step 1 Turn the power switch to the ON position.
Step 2 Verify that the Ready LED turns green after all connections are loaded (this may take up to ten minutes).
|
Note If the Ready LED does not turn green after ten minutes, contact Customer Support. |
On power up, the PSM starts diagnostics, including register, RAM, and control (interrupts). Where appropriate, multiple functional blocks are tested, with the use of loopback functionality. The Startup BERT Loopback test follows the hardware diagnostics.
After each sub-system has been individually tested, the data paths between sub-systems are tested. After the diagnostics are completed, the PSM loads the Operating software from flash into RAM. Then the PSM reads and processes the configuration files from the Flash. By doing so, the system configures ports and makes connections. After all the configuration files are executed, the Ready LED turns green, signalling that provisioning is finished.
The internal OAM Loopback test runs continuously. If it fails, the health monitor reboots the system.
Perform First Day of Service (FDOS) on the MGX 8240 to verify that the switch is ready to be managed by the Network Management System.
Before starting FDOS, you need the following:
Perform the following steps to make an RS232 terminal connection:
Step 1 Use the RS232 DCE RJ45 connector to connect the cable between the VT-100 terminal and MGX 8240.
Step 2 Configure terminal device for VT-100 with a baud rate of 9600 (8, N, 1).
Step 3 Configure the Ethernet Connector Signal list (RJ45 connector).
Table 1-5 and Table 1-6 show the Ethernet and RS232 connector signal lists.
| Pin No. | Signal |
|---|---|
1 | TDP (Transmit Data Positive) |
2 | TDN (Transmit Data Negative) |
3 | RDP (Receive Data Positive) |
4 | No Connect |
5 | No Connect |
6 | RDN (Receive Data Negative) |
7 | No Connect |
8 | No Connect |
| Pin No. | Signal |
|---|---|
1 | CTS (Clear to Send) |
2 | DTR (Data Terminal Ready) |
3 | TXD (Transmit Data) |
4 | Ground |
5 | Ground |
6 | RXD (Receive Data) |
7 | DSR (Data Set Ready) |
8 | RTS (Ready to Send) |
The Craft Interface/Console Management Diagnostic Resource (CMDR or Commander) is the menu-based tool available to set up FDOS. The menu-based tool is easily invoked when a user logs in through the serial port into the switch. CMDR is menu based and several menus are available.
To set up the Craft Interface/CMDR, connect your VT-100 terminal (or laptop) via the RS232c cable to the serial port on the module.
To begin FDOS, perform the following steps:
Step 1 Enter CMDR and press <Enter>.
Step 2 Enter your username and password on the Login menu (Default is ultimate/ultimate; sysadmin/sysadmin may also work).
Figure 1-10 shows the Login procedure.
Step 3 To display the menu mode, enter menu.
The Main menu displays (see Figure 1-11).
Step 4 Use the following keys to navigate through the screens:
The instructions below are to be followed only on a chassis that has the CIM. For a chassis using the IMC card, go to FDOS on PSM Cards in Chassis Using IMC.
As each card is installed, you need to set the following values:
Set the node IP address by using the Node Setup menu. Perform the following steps:
Step 1 Move the cursor to Node Setup and press <Enter>. The Node Setup menu displays.
Step 2 To change the Node IP address, select Node Configuration for the Node Configuration Window (see Figure 1-12).
Step 3 Position the cursor at the System Location blank and enter the location.
Step 4 Position the cursor at the System Name blank and enter the name.
Step 5 Position the cursor at the IP address and enter the new IP address over the old one.
|
Note If you do not use the default IP address and set the subnet mask to 255.255.255.0, redundancy will not work. |
Step 6 Set the Subnet Mask to 255.255.255.0.
Step 7 Use Default Gateway as the IP address of the router to direct all external IP packets towards.
Step 8 After entering all of the above information, press <F1> to update the configuration information in memory. For this information to take effect, the node requires a reboot (this is done in Step 16).
Step 9 At the power restart, the CMDR dialog box prompts you to reboot the system. Enter No.
Step 10 To program the MGX 8240 node to send traps to the management station, perform the following steps:
(a) From the Node Setup menu, press <Enter>.
(b) Select the SNMP Configuration menu. The SNMP Configuration displays (see Figure 1-13).
Step 11 Press <Enter>. This enters the information related to the Trap manager. The Trap Report menu displays (see Fig. 1-14).
Step 12 With the cursor on New, press <Enter> again to see the New Manager submenu (see Figure 1-15).
Step 13 Position the cursor on the IP address area and enter the IP address of the workstation to receive the traps.
Step 14 Select Send Traps and enter Yes. Leave all other information unchanged (Port = 162, Trap = Public).
Step 15 To make the changes effective, press <F1>. Perform a card restart to make these changes effective. After a restart, the card can be managed remotely and can receive traps using SNMP. This operation should be extended to all cards in the network.
Step 16 Exit the menu system after all configuration changes are made. The prompt changes to CMDR>>.
Step 17 Reboot the system by entering the following command:
oper rebootStep 18 You must reboot the system for all changes to take place.
|
Note Before beginning FDOS on any PSM card, you must have done FDOS on the IMC card. |
All cards in the MGX 8240 chassis can have FDOS provisioning done through the primary IMC. Users open a CMDR session for each PSM to allow FDOS provisioning.
As each card is installed, you need to set the following values:
Step 1 In a terminal window, at the login prompt, enter the following command:
sysadminStep 2 At the password prompt, enter the following command:
sysadmin |
Note In CMDR it is not necessary to type the whole command, but only the first letter(s) unique to the commands. |
Step 3 This first screen will have five options (Node Setup, Administration, Statistics, Help, Exit). Node Setup will be highlighted. Press <Enter>.
