The following service considerations should be taken into account when handling HP racks:
If installing a single rack, ensure that the rack is level and has been stabilized before installing the components. Stabilizing feet are not required on the back of a standalone rack. To reduce risk of personal injury, attach HP rack stabilizing feet to all standalone racks.
There is a leveling foot at each corner of the rack, which should be fully extended, screwed down, and locked in place with a locking nut before any component is installed on the rack. To reduce the risk of damage to the casters, ensure that the full weight of the rack rests on the leveling feet rather than the casters. The casters are designed only as an aid in moving the rack into position.
Join multiple racks with a coupling kit to increase stability. Position the racks and install the coupling kits before populating the racks with components.
When installing the various components, mount the heaviest components first in the bottom of the rack. The UPS should always be on the bottom.
Do not simultaneously extend more than one component from the rack. Doing so can cause the rack to become unstable and tip.
Rack-mountable ProLiant servers draw in cool air through the front door and exhaust warm air out the rear. Therefore, the front door must be adequately ventilated to allow ambient room air to enter the cabinet, and the rear door must be adequately ventilated to allow the warm air to escape from the cabinet.
Blanking plates should be used to cover any spaces where components are not mounted. Blanking plates are essential for correct airflow. When servicing a customer's rack system, if you notice that blanking plates are missing, ask the customer to install them.
In the event of a lost key for a rack, contact a locksmith for assistance. Replacement key lock assemblies can be ordered from HP.
