# Removing a Line Module, SRP Module, or SRP I/O Module

| Note: We recommend that you issue the slot disable command from the CLI before removing a line module or I/O module.

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

To remove a line module, SRP module, or SRP I/O module:

1. For SRP modules and SRP I/O modules, issue the appropriate halt command (halt, halt primary-srp, or halt standby-srp).

   See JunosE System Basics Configuration Guide, Chapter 6, Managing Modules for information about the halt commands.

2. Ground yourself by using an antistatic wrist strap or other device and connect it to the ESD grounding jack on the chassis.
3. Use a screwdriver (using a No. 2 Phillips screwdriver, if necessary) to loosen the thumb screws located at the top and bottom of the module panel.
4. If the module has ejector handles, pull them to the open position, as shown in Figure 21.

5. Carefully slide the module out of the chassis.
6. Place the module in its antistatic bag, being careful not to touch module components, pins, leads, or solder connections.
7. Cover the empty chassis slot with a blank filler panel, and tighten the filler panel's captive screws using a No. 2 Phillips screwdriver. Turn both screws several times before tightening them completely.

   | Caution: Do not overtighten the screws.

If you remove an I/O module and not the corresponding line module, the line module reboots. Its status becomes inactive when you issue the show version command.

If you remove a line module and do not delete the corresponding configuration, the status of the line module is listed as not present when you issue the show version command.
