Powering Off an XRE200 External Routing Engine That Has CLI Access

• Ensure that you understand how to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.

• Ensure that you do not need to forward traffic through the external Routing Engine.

• An ESD grounding strap

• An external management device such as a PC

• A cable to connect the external management device to the console port (labeled (CON) or management port (labeled MGMT) on the external Routing Engine

To power off an external Routing Engine:

1. Connect the management device to the external Routing Engine. See either Connect a Device to a Management Console Using an RJ-45 Connector or Connect a Device to a Network for Out-of-Band Management.
2. From the external management PC connected to the primary external Routing Engine, issue the request system halt other-routing-engine operational mode CLI command.

   This command shuts down the backup external Routing Engine gracefully. A message displays on the console confirming that the backup external Routing Engine has halted.

3. Shut down the primary external Routing Engine from the external management device by issuing the request system halt operational mode CLI command. This command shuts down the external Routing Engine 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 shut down) after you enter the command:

   content_copy zoom_out_map

   Caution

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

4. Observe the power supply LED and verify that it is unlit. Repeat this step for all external Routing Engines in the EX8200 Virtual Chassis.

Powering Off an XRE200 External Routing Engine That Does Not Have CLI Access

• Ensure that you understand how to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.

• Ensure that you do not need to forward traffic through the external Routing Engine.

• An ESD grounding strap

To power off an external Routing Engine that does not have access to the CLI:

1. Push the power button on the rear panel of the XRE200 External Routing Engine. Hold the power button down for more then 1 second but less then 4 seconds.
   Note

   Holding the power button down for 4 or more seconds triggers a hard reset. In rare cases, a hard reset can corrupt file systems on an XRE200 External Routing Engine. Use the hard reset only as a last resort to power off the external Routing Engine to avoid this risk.

2. Observe the power supply LED. The power supply LED should turn off (appear unlit).
3. If you are unable to power off the external Routing Engine in Step 1, retry Step 1.
4. If you are still unable to power off the external Routing Engine, push the power button on the rear panel of the external Routing Engine and hold the power button down for 4 or more seconds to start a hard reset.

Removing an XRE200 External Routing Engine from a Rack or Cabinet

If you need to relocate an installed XRE200 External Routing Engine, use the procedure described in this topic. (The remainder of this topic uses “rack” to mean “rack or cabinet.”)

Before removing an external Routing Engine from a rack:

• Ensure that the rack is stable and secured to the building.

• Ensure that there is enough space to place the removed external Routing Engine in its new location and along the path to the new location.

• Read General Safety Guidelines and Warnings.

• Ensure that the external Routing Engine has been safely powered off (see Powering Off an XRE200 External Routing Engine) and that you have unplugged (disconnected) the power cords or cables.

• Ensure that you have disconnected any cables or wires attached to the external Routing Engine ports.

• A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack mounting screws, for mounting the external Routing Engine on the rack

To remove an external Routing Engine from a rack:

1. Use the screwdriver to remove the mounting screws that attach the chassis brackets to the rack.
2. Place the removed screws in a labeled bag. You will need them when you reinstall the chassis.
3. Lift the external Routing Engine from the rack and transport it to your desired new location.
