Installing Line Modules and Their I/O Modules
This section describes the procedures for installing line and I/O modules.
Note: Install the I/O module before you install the corresponding line module; otherwise, the ERX system diagnostics fail, and after the line module has tried to reboot, its status will be "inactive" when you issue a show version command.
Installing a Line Module or an I/O Module
To install a module:
- Connect the antistatic wrist strap to the ESD grounding jack on your ERX system.
Caution: When handling modules, use an antistatic wrist strap connected to the ERX system's ESD grounding jack. This action helps to protect the module from damage by electrostatic discharge.
- Identify the front and back of the system.
You install line modules in the front of the system and I/O modules in the back of the system (see Figure 3-8).
- Choose the slot where you want to insert the module.
- For the ERX-1440 system, you can install the OC48 line module in slots 2-3 and slots 4-5. Install the corresponding I/O module only in the lower of the two slots (either slot 2 or slot 4) that the line module spans.
- For the ERX-1440 system, you can install modules other than the OC48 modules in slots 0-5 and slots 8-13.
- For the ERX-1410 system, you can install modules in slots 0-5 and slots 8-13.
- For the ERX-700 series, you can install line modules and their corresponding I/O modules in slots 2-6.
- With a Phillips screwdriver, loosen the top and bottom screws that secure the blank faceplate covering the empty chassis slot.
- Remove the faceplate.
Caution: Always handle the module by its edges. Do not touch the components, pins, leads, or solder connections.
- Remove the module from its antistatic bag.
- Make sure that the ejectors are in position 1, as shown in Figure 3-6.
- Position the module as follows:
- For the ERX-1400 series, position the module vertically so that the labeling is upright.
- For the ERX-700 series, position the module horizontally so that the labeling is to the right.
- Guide the module into the chassis by placing it between the guides of the selected slot, and slide the module until it stops.
The module stops sliding when the ejectors make contact with the front of the chassis. Figure 3-8 shows how to install an I/O module and a line module in the ERX-1400 series.
- Insert the module into the midplane by simultaneously depressing both ejectors (as shown in Figure 3-6) and exerting forward pressure on the module.
- Tighten the module's captive screws using a Phillips screwdriver. Turn both screws several times before tightening them completely to allow the module to sit correctly.
- Cable each module to provide a path to the remote interface (see Chapter 4, Cabling the ERX System).
