Removing An Srp Module - Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X Configuration Manual

Removing an SRP Module

Before you remove an SRP module, you must issue the halt command, which stops
operation on that module. If the router contains both primary and redundant SRP
modules, you can specify which modules the command should affect.You can also
configure the router to prompt you when the modules are in a state that might lead
to loss of configuration data or NVS corruption.
CAUTION: If you do not use the halt command before removing or powering down
an SRP module, the router's NVS may become corrupted.
For information about physically removing an SRP module, see ERX Hardware Guide,
Chapter 4, Installing Modules.
halt
When you issue the adapter enable command in a redundancy configuration,
the line module (primary or spare) currently associated with that IOA is rebooted.
If the IOA is protected by a line module redundancy group, an automatic line
module redundancy switchover or revert can be triggered by the line module
reboot. To prevent undesired line module redundancy actions, issue the
redundancy lockout command for the primary line module slot before issuing
the adapter enable command. For more information, see Line Module Redundancy
in JUNOSe Services Availability Configuration Guide.
In the software, adapter 0 identifies the right IOA bay (E120 router) and the
upper IOA bay (E320 router); adapter 1 identifies the left IOA bay (E120 router)
and the lower IOA bay (E320 router).
Example Enables the IOA residing in the upper bay of slot 5 in an E320 router

Use to stop the router's operation before you remove or power down an SRP
module
The following guidelines apply when you issue the halt command in Privileged
Exec mode:
Specify neither the primary-srp nor the standby-srp keyword to stop
operation on both SRP modules.
Specify the keyword primary-srp to stop operation on the primary SRP
module only. This action causes the redundant SRP module to assume the
primary role.
Specify the keyword standby-srp to stop operation on the redundant SRP
module only.
If you do not specify the force keyword, the procedure fails if:
