Removing a QFX10016 From a 4-Post Rack Using a Mechanical Lift
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
QFX10000 Clearance Requirements for Airflow and Hardware Maintenance
.
• Review "General Safety Guidelines and Warnings" on page 386 .
• Review the chassis lifting guidelines described in
QFX10002 Installation Safety Guidelines
.
• Ensure that the switch has been safely powered off.
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)
• A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack-mounting
screws
Because of the switch's size and weight, we only recommend using a mechanical lift to install the
QFX10016.
To remove the switch using a mechanical lift (see Figure 198 on page 353 ):
1. Use the appropriate Phillips (+) screwdriver to remove the 12 mounting screws that attach the
chassis front-mounting brackets to the rack.
2. Move the lift to the rack and position it so that its platform is centers 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.
