Powering Off the Line-Card Chassis

To power off the line-card chassis (LCC):

  1. On the external management device connected to the Routing Engine, issue the request system halt both-routing-engines operational mode command. The command shuts down both Routing Engines cleanly, so their state information is preserved. (If the router contains only one Routing Engine, issue the request system halt command.)
    user@host> request system halt both-routing-engines

    For more information about this command, see request system halt.

  2. Wait until a message appears on the console confirming that the operating system has halted.
  3. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  4. Switch the circuit breakers on each power supply faceplate to the off position (O or power switch on each power supply faceplate to the standby position.
  5. Switch off the external customer site circuit breakers to the power supplies.

Upgrading the SIBs

  1. Verify that the LCC is powered off. All LEDs should be unlit.
  2. Replace the SIBs. See the following documentation:
