3.3.2 Securing the rack


3.3.2 Securing the rack
When installing the rack, always adjust the leveling feet as follows, regardless of whether the rack will be anchored to the building floor. Keep the rack level with the leveling feet. Make sure that the casters are approximately 2 mm (0.1 in.) above the floor surface. The casters must not support the weight of the rack.
For fixed installations of the rack
  1. Fixing in place using the quakeresistant options kit
    Attach the quakeresistant options kit (which is optional so must be ordered separately) around the rack (front, rear, and sides), and fix it to the slab (building floor) by using the holes in the kit.

  1. Fixing in place using the leveling feet
    Fix the rack to the slab (building floor) by using holes with a depth of 17 mm (0.7 in.) for screws of size M20 on the bottom of the leveling feet of the rack.

For non-fixed installations of the rack
  1. Fixing in place using the toppling prevention stabilizer
Note - Attach the stabilizer as a measure to prevent the rack from toppling during system maintenance. For non-fixed installations, always attach the stabilizer when installing the rack.
The stabilizer is attached to the rack as shown below.

Warning - For a non-fixed installation of a rack, order the stabilizer and be sure to attach it. Pulling out the chassis from a rack without a stabilizer attached may cause the rack to topple over.
