Removing an EX9208 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.

Removing an EX9208 Switch from a Rack or Cabinet Without Using a Mechanical Lift

If you cannot use a mechanical lift to remove an EX9208 switch from a rack or a cabinet (the preferred method), you can remove it manually.

Caution

The chassis with only the backplane and no other components weighs approximately 65.5 lb (29.7 kg). Lifting the chassis and removing it from a rack or cabinet requires at least three people.

The chassis has two handles. Do not lift a fully loaded chassis by the handles; make sure the chassis is empty before you lift it. If two of the people lifting the chassis use the handles to lift it, the third person must lift from the rear of the chassis. The rear of the chassis is heavier than the front of the chassis, so when you lift the chassis by the handles, the chassis tips toward the heavier back end. The person lifting from the back must be aware of this behavior and must be braced to prevent the chassis from tipping over.

When lifting the chassis, do not grasp the switch by the blue panel at the top front of the chassis. Doing so can cause the panel to pop off of the switch.

Caution

When removing more than one switch from a rack, remove the switch at the top first. We strongly recommend removing a switch that is in an upper position in a rack or cabinet with a lift.

Before you remove the switch:

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

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

To remove the switch from the rack:

  1. Use the appropriate screwdriver to remove the 24 mounting screws that attach the chassis front-mounting brackets to the rack or cabinet.Warning

    To prevent injury, keep your back straight and lift with your legs, not your back. Do not twist your body as you lift. Balance the load evenly and be sure that your footing is firm.

  2. With one person on each side and one person at the back, hold onto the bottom of the chassis and carefully lift it out of the adjustable mounting brackets attached to the rack. If you have a pallet jack, move the switch onto the pallet jack.
  3. Carefully move the chassis to its new location.

After you move the switch to its new location, reinstall the components in the chassis or store the components in antistatic bags. See:
