Because of the switch's size and weight, we only recommend using a mechanical lift to
install the QFX10016.
Before you remove the switch using a lift:
Ensure that the rack is stable and secured to the building.
Ensure there is enough space to place the removed switch in its new location and along
the path to the new location. See
Hardware Maintenance" on page
Review "General Safety Guidelines and Warnings" on page
Review the chassis lifting guidelines described in Chassis Lifting Guidelines.
Ensure that the switch has been safely powered off (see
on page 261).
CAUTION: When removing more than one switch chassis from a rack, remove
the switches in order from top to bottom.
Ensure that you have the following parts and tools available to remove the switch:
A mechanical lift rated for 1000 lbs. (453.6 kg)
