Chapter 13 Alternative Rack Mounting Rack-mounting Guidelines and Precautions Observe the following guidelines and safety precautions during the rack-mount installation. l Extend the rack's anti-tip foot prior to any work on the rack to prevent rack tip-over, equipment damage, and injury. WARNING Lower the leveler feet at the four corners of the rack to improve stability and prevent the rack from rolling away as devices are inserted into their rack mounts. Failure to use the anti-tip foot or the anti-tip device and leveler feet could result in serious injury. l Uneven mechanical loading within the rack can cause hazardous conditions. Plan the placement of equipment in the rack to make sure that this problem does not occur. ◊ Install components from the bottom up. ◊ Place the heaviest components on the bottom of the rack. CAUTION If other rack components are to be mounted in the rack below the HP NetServer, install those components before starting to mount the HP NetServer. ◊ Use HP Rack Assistant to plan the rack configuration and to check power, weight, and stability of the configured rack.
