Removing a Module

To remove a module:

Caution: If you do not use the halt command before removing or powering down an SRP, the system's NVS card may become corrupted.

  1. Enter the halt command.

See ERX System Basics Configuration Guide, Chapter 5, Managing Line Modules and SRP Modules for information about the halt command.

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.

  1. Connect the antistatic wrist strap to the ESD grounding jack on your ERX system.
  2. Use a screwdriver to loosen the thumb screws located at the top and bottom of the module panel, as shown in Figure 3-5.
  3. Raise the ejector handles located at the top and bottom of the module so that they are in position 2, as shown in Figure 3-7.

Caution: Always handle the module by its edges. Do not touch the components, pins, leads, or solder connections.

  1. Carefully slide the module out of the chassis, as shown in Figure 3-9.
  2. Place the module in its antistatic bag.
  3. Cover the empty chassis slot with a blank faceplate. Tighten the faceplate's top and bottom captive screws using a Phillips screwdriver, as shown in Figure 3-10. Turn both screws several times before tightening them completely.

If you remove an I/O module and not the corresponding line module, the line module reboots, and then its status will be "inactive" when you issue a show version command. If you remove a line module and do not delete the corresponding configuration, the status of the line module will be "not present" when you issue a show version command.
