Powering Off an EX8200 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 (MGMT) on the master Switch Fabric and Routing Engine (SRE) module in an EX8208 switch or on the master Routing Engine (RE) module in an EX8216 switch.

To power off a switch:

  1. Connect a management device to the master SRE module in an EX8208 switch or to the master RE module in an EX8216 switch. For connecting a management device to the console (CON) port, see Connecting a Device to a Management Console by Using an RJ-45 Connector. For connecting a management device to the management (MGMT) port, see Connecting a Device to a Network for Out-of-Band Management.
  2. If the switch has two SRE or RE modules, shut down the backup SRE or RE module first. (If your switch has only one SRE or RE module, skip to Step 2.) From the external management PC connected to the master SRE or RE module, issue the request system halt other-routing-engine operational mode CLI command.

    This command shuts down the backup SRE or RE module gracefully. A message displays on the console confirming that the backup SRE/RE module has halted.

  3. Shut down the master SRE or RE module from the external management device by issuing the request system halt operational mode CLI command. This command shuts down the switch gracefully and preserves system state information. A message displays on the console confirming that the operating system has halted.

    You will see the following output (or something similar, depending on the hardware being shutdown) after entering the command:

    Caution

    The final output of any version of the request system halt command is the “The operating system has halted. Please press any key to reboot” message. Wait at least 60 seconds after first seeing this message before following the instructions in step 5 to power off the switch.

  4. Attach the ESD grounding strap to your bare wrist and connect the strap to the ESD point on the chassis.
  5. Flip the power supply Enable switch to the off position (OFF). Observe the power supply LEDs. The power supply LEDs should turn off (appear unlit). Repeat this step for all installed power supplies.
Note

After you power off a power supply, wait for at least 60 seconds before you turn it back on. After you power on a power supply, wait for at least 60 seconds before you turn it back off.
