Installing the System Rack 4-7
Leveling the System Rack
When the rack is removed from the pallet and placed in its permanent location,
you will extend the lifecycle of mechanical components by leveling the your
rack.
Before leveling the rack, position the rack to conform with the space
requirements specified in Chapter 2 and verify that your power receptacle is
within six feet of the rear of your rack. To level the rack:
1. Lower the leveling foot located in each corner of the rack until they all make
contact with the floor. See Figure 4-4
Figure 4-4. Leveling Foot Adjustment
2.
Using your level, check the vertical and horizontal planes of the rack for
level. Level your system rack by turning the adjusting nut on the top of each
foot as needed.
3. Secure each leveling foot by tightening the lock nut up against the
underside of the rack.
