Replacing an NVS Card

70
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:
Wear an antistatic wrist strap and connect it to one an ESD grounding jack on the
1.
router.
Halt the redundant SRP module.
2.
host1#halt standby-srp
Remove the redundant SRP module from the chassis.
3.
Replace the NVS card on this SRP module. (See "Replacing an NVS Card" on page 70.)
4.
Reinsert the SRP module into the chassis.
5.
When this SRP module is available, synchronize the SRP modules.
6.
host1#synchronize
When the SRP modules are synchronized, reboot the SRP module that you upgraded.
7.
host1#reload standby-srp
When this SRP module is available, synchronize the SRP modules.
8.
host1#synchronize
When the SRP modules are synchronized, force the redundant SRP module to take
9.
over from the primary SRP module.
host1#srp switch
Halt the redundant (former primary) SRP module.
10.
host1#halt standby-srp
Immediately remove the former primary SRP module.
11.
Repeat Steps 4–8 for the former primary SRP module.

To replace an NVS card in slot 0 or slot 1 of an SRP module:
CAUTION: Before you insert or remove an NVS card from a running SRP
module, we strongly recommend that you halt the SRP module or shut down
the router. Failure to do this can result in file corruption in one or both cards.
See JunosE System Basics Configuration Guide, Chapter 6, Managing Modules
for information about the halt command.
