CAUTION: Thechassis with only the backplane and no other components weighs
approximately89 lb (41 kg).Lifting the chassis and removing it from a rack or cabinet
requiresat least three people.
Thechassis has two handles. Do not lift a fully loadedchassis by the handles; make
surethe chassis is empty before you lift it. If two of the peoplelifting the chassis use
thehandles to lift it, the third person must lift from the rear of the chassis. Therear of
thechassis is heavier than the front of the chassis, so when you lift the chassis by the
handles,the chassis tips toward the heavierback end. The person lifting from the back
mustbe aware of this behavior and must be bracedto prevent the chassis from tipping
over.
Whenlifting the chassis, do not grasp the switch by the blue panel atthe top front of
thechassis. Doing so can cause the panel to pop off of the switch.
CAUTION: Whenremoving more than one switchfrom a rack, remove the switch at the
topfirst. We strongly recommendremoving a switch that is in an upper position in a
rackor cabinet with a lift.
Beforeyou remove the switch:
•Ensurethat the rack or cabinet is stable and securedto the building.
•Ensurethat there is enough space to placethe removed switch in its new location and
alongthe path to the new location.
•Reviewchassislifting guidelines as described in “Chassis Lifting Guidelines for EX8200
Switches”on page 276.
•Ensurethat the switch has been safelypowered off (see “Powering Off an EX8200
Switch”on page199) and that you have unplugged (disconnected)the power cords to
thepower supplies.
•Ensurethat you have disconnected anycables or wires attached to the switch ports.
•Removeall components except the backplanefrom the chassis. See:
