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 chassishas 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 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
shift it along the path to the new location.
•
Review chassis lifting guidelines as described in Chassis Lifting Guidelines for EX9200
Switches.
