Removing an EX8208 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 EX8208 Switch from a Rack or Cabinet

If you want to move an installed EX8208 switch to another location, you need to remove it from the rack or cabinet in which it is installed. In a four-post rack, an installed switch rests on adjustable mounting brackets bolted to the rack. In a two-post rack, an installed switch rests on the lip of the power cord tray installed in the rack. The front-mounting brackets (“ears”) attached to the chassis are also bolted to the rack.

Note

When you remove multiple switches 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.

Caution

At least three people must be available to lift an unloaded switch chassis (all components removed) out of a rack or cabinet. For instructions on removing a switch without using a mechanical lift, see Removing an EX8208 Switch from a Rack or Cabinet Without Using a Mechanical Lift.

Before removing an EX8208 switch from a rack or a cabinet:

  • Ensure that the rack or cabinet 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.

  • Ensure that you have disconnected any cables or wires attached to the switch ports.

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, for mounting the switch on a rack or cabinet.

  • A Phillips (+) screwdriver, number 1, to remove the power supplies from the chassis if you are mounting the switch without using a mechanical lift

To remove an EX8200 switch from a rack or cabinet:

  1. Use the appropriate Phillips (+) screwdriver to remove the mounting screws that attach the chassis front-mounting brackets to the rack or cabinet.
  2. Place the removed screws in a labeled bag. You will need them when you reinstall the chassis.
  3. Lift the chassis from the rack or cabinet and place it on a mechanical lift. For instructions on how to remove the chassis using a mechanical lift, see Removing an EX8208 Switch from a Rack or Cabinet Using a Mechanical Lift. If a mechanical lift is not available, remove all components and manually lift the empty chassis out of the rack. For instructions on removing the chassis without using a mechanical lift, see Removing an EX8208 Switch from a Rack or Cabinet Without Using a Mechanical Lift.

Removing an EX8208 Switch from a Rack or Cabinet Using a Mechanical Lift

Because of the switch's size and weight, we strongly recommend using a mechanical lift to remove the switch. For instructions on removing a switch without using a mechanical lift, see Removing an EX8208 Switch from a Rack or Cabinet Without Using a Mechanical Lift.

Before you remove the switch using a lift:

  • Ensure that the rack or cabinet 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 to the power supplies.

  • Ensure that you have disconnected any cables or wires attached to the switch ports.

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 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 24 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.

If you cannot use a mechanical lift to remove the switch (the preferred method), you can remove it manually.

Caution

The chassis with only the backplane and no other components weighs approximately 89 lb (41 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 (see Figure 2):

  1. Use the appropriate Phillips (+) 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 in 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:
