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:

Enter the halt command.

See JunosE System Basics Configuration Guide, Chapter 6, Managing Modules for

information about the halt command.

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.

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 page 70.)

Reinsert the SRP module into the chassis.

Power up the system. (See "Powering Up the Router" on page 55.)

In a system that contains two SRP modules, you can upgrade the NVS cards on the SRP

modules without powering down the system.
