Removing an EX8216 from a Rack or Cabinet

 

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.

Removing an EX8216 Switch from a Rack or Cabinet

If you want to move an installed EX8216 switch to another location, you need to remove it from the rack or cabinet in which it is installed. (The remainder of this topic uses “rack” to mean “rack or cabinet.”) An installed switch rests on adjustable mounting brackets bolted to the rack. The front-mounting brackets (“ears”) attached to the chassis are also bolted to the rack.

Warning

Because of the switch's size and weight, we require the use of a mechanical lift to remove the switch.

Note

If you are removing more than one switch in a rack, remove the first switch from the top of the rack.

Before removing an EX8216 switch from a rack:

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

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

  • Read General Safety Guidelines and Warnings, with particular attention to Chassis and Component Lifting Guidelines.

  • Ensure that the switch has been safely powered off (see Powering Off an EX8200 Switch) and that you have unplugged (disconnected) the power cords or cables from the power supplies.

  • Ensure that you have disconnected any cables or wires attached to the switch ports, the console and management ports, and the protective earthing terminals.

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

  • A mechanical lift

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

To remove the switch using a lift (see Figure 1):

  1. Use the appropriate Phillips (+) screwdriver to remove the mounting screws that attach the chassis front-mounting brackets to the rack.
  2. Place the removed screws in a labeled bag. You will need them when you reinstall the chassis.
  3. Move the lift to the rack and position it so that its platform is centered about 0.5 in. (1.27 cm) below the bottom of the switch chassis and as close to it as possible.
  4. Carefully slide the switch from the adjustable mounting brackets attached to the rack onto the lift.
  5. Use the lift to transport the switch to its new location.
