Upgrading a System That Contains Two SRP Modules

In a system that contains two SRP modules, you can upgrade the NVS cards on the SRP modules without powering down the system.

Warning: Do not insert any metal object, such as a screwdriver, or place your hand into an open slot or the backplane when the router is on. Remove jewelry (including rings, necklaces, and watches) before working on equipment that is connected to power lines. These actions prevent electric shock and serious burns.

Caution: When handling modules, use an antistatic wrist strap connected to an 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. Wear an antistatic wrist strap and connect it to one an ESD grounding jack on the router.
2. Halt the redundant SRP module.

3. Remove the redundant SRP module from the chassis.
4. Replace the NVS card on this SRP module. (See Replacing an NVS Card.)
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 standby-srp

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.
