Maintaining ERX Routers
CAUTION: When handling modules, use an antistatic wrist strap connected to the
router’s ESD grounding jack. This action helps to protect the module from damage
by electrostatic discharge.
To upgrade the NVS cards on the SRP modules in a system that
contains two SRP modules:
1. Connect the antistatic wrist strap to the ESD grounding jack on your router.
2. Halt the redundant SRP module.
host1#halt standby-srp
3. Remove the redundant SRP module from the chassis.
4. Replace the NVS card on this SRP module. (See “Replacing an NVS Card” on
page 89.)
5. Reinsert the SRP module into the chassis.
6. When this SRP module is available, synchronize the SRP modules.
host1#synchronize
7. When the SRP modules are synchronized, reboot the SRP module that you
upgraded.
host1#reload slot 7
8. When this SRP module is available, synchronize the SRP modules.
host1#synchronize
9. When the SRP modules are synchronized, force the redundant SRP module to
take over from the primary SRP module.
host1#srp switch
10. Halt the redundant (former primary) SRP module.
host1#halt standby-srp
11. Immediately remove the former primary SRP module.
12. Repeat Steps 4–8 for the former primary SRP module.
