Upgrading a System That Contains One SRP Module
If the system contains only one SRP module, you must power down the system
before you upgrade the NVS card.
CAUTION: If you do not use the halt command before removing or powering down
an SRP module, the system's NVS card can become corrupted.
To upgrade the NVS card on a system that contains one SRP module:
1.
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.

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.
Enter the halt command.
See JUNOSe System Basics Configuration Guide, Chapter 6, Managing Modules for
information about the halt command.
Connect the antistatic wrist strap to an ESD grounding jack on the router.
Power down the system.
Remove the SRP module.
Replace the NVS card on the SRP module. (See "Replacing an NVS Card" on
