Juniper EX8200 Series User manual

Removing an EX 8200 series 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 EX 8200 series 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 for EX-series Switches, with
particular attention to Chassis Lifting Guidelines for EX 8200 series Switches.
■Ensure that the switch has been safely powered off (see Powering Off an EX
8200 series 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 on page 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.
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.
