Removing Modules and IOAs

40
NOTE: Tighten the captive screws completely before installing an adjacent
module so that proper EMI gasket compression occurs. Failure to do this
can make it difficult to install adjacent modules.
CAUTION: Do not overtighten the screws.
This section describes the procedures for removing modules and IOAs. For a list of
hot-swappable IOAs, see Table 4 on page 30.
NOTE: We recommend that you issue the slot disable command from the
CLI before removing a line module or IOA.
CAUTION: If you do not use the halt command before removing or powering
down an SRP module, the system's NVS card can become corrupted.
To remove a module or an IOA:
For SRP modules and SRP IOAs, issue the appropriate halt command (halt, halt
1.
primary-srp, or halt standby-srp).
See JunosE System Basics Configuration Guide, Chapter 6, Managing Modules for
information about the halt commands.
Ground yourself by using an antistatic wrist strap or other device and connect it to an
2.
ESD grounding jack.
Use a No. 2 Phillips screwdriver to loosen the captive screws located at the top and
3.
bottom of the module panel.
If the module has ejector handles, pull them to the open position, as shown in Figure
4.
