Upgrading NVS Cards on SRP Modules
When handling modules, use an antistatic wrist strap connected to the
CAUTION:
E-series 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 E-series
router.
2. Halt the redundant SRP module.
host1#halt standby
3. Remove the redundant SRP module from the chassis.
4. Replace the NVS card on this SRP module (see
this chapter).
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
11. Immediately remove the former primary SRP module.
12. Repeat steps 4–8 for the former primary SRP module.
To replace an NVS card on an SRP module:
1. Obtain an antistatic container for the NVS card you will remove (see
Modules and Components, earlier in this chapter).
