Removing an EX9214 from a Rack or Cabinet

 

Powering Off an EX9200 Switch

Before you power off the switch:

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

  • An ESD wrist strap

  • An external management device such as a PC

  • A cable to connect the external management device to the console port (CONSOLE) or management port (<...>) on the primary Routing Engine module (RE module).

To power off the switch:

  1. Connect a management console device to the primary RE module. For information about connecting a management device to the console (CONSOLE) 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. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the switch.
  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.

Removing an EX9200 Switch from a Rack or Cabinet Using a Mechanical Lift

Considering the size and weight of the switch, we strongly recommend you use a mechanical lift to remove the switch.

Before you remove the switch using a lift:

Caution

When removing more than one switch from a rack or cabinet, remove the switch in the top of the rack or cabinet first and proceed to remove the rest of the switches from top to bottom.

Ensure that you have the following parts and tools available:

  • A mechanical lift

  • A Phillips (+) screwdrivers, number 1 and 2

To remove the switch using a lift:

  1. Use the appropriate screwdriver to remove the mounting screws that attach the chassis front-mounting brackets to the rack or cabinet.
  2. 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.
  3. Carefully slide the switch from the adjustable mounting brackets attached to the rack onto the lift.
  4. Use the lift to transport the switch to its new location.
