    Powering Off an EX9208 Switch

    Before you power off the switch:

    Ensure that you have the following parts and tools available to power off the switch:

    • An electrostatic discharge (ESD) grounding strap
    • An external management device such as a PC
    • A cable to connect the external management device to the console port (CON) or management port (<...>) on the master Routing Engine (RE) module.

    To power off the switch:

    1. Connect a management console device to the master RE module. For information about connecting a management device to the console (CON) port, see Connecting an EX9200 Switch to a Management Console or an Auxiliary Device. For information about connecting a management device to the Ethernet management (<...>) port, see Connecting an EX9200 Switch to a Network for Out-of-Band Management.
    2. 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 the Routing Engines cleanly, so their state information is preserved. (If the switch contains only one Routing Engine, issue the request system halt command.)

      For more information about these commands, see the Junos OS Operational Mode Commands.

    3. Wait until a message appears on the console confirming that the operating system has halted.
    4. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
    5. Move the AC input switch on each AC power supply, or the DC circuit breaker on each DC power supply to the off (O) position.
