Rack-mount Related Notices

!WARNING

To avoid a risk of injuries, users should not attempt to install the equipment into a rack. Installation should be performed by trained maintenance personnel.

It takes at least two people to carry or maneuver a rack. Otherwise, it may be dropped and cause injuries or damage to physical assets. A tall rack (such as 44U rack) is quite unstable, especially when not fixed by stabilizers.

For stability and to distribute the weight, attach stabilizers or install two or more racks together. Otherwise, the rack may topple over and cause injuries.

It takes at least two people to mount doors and trays to a rack. Otherwise, parts may be dropped causing breakage or injuries.

If you extend two or more devices from the rack at the same time, the rack may topple over on you. Extend only one device from the rack at a time.

Install the equipment into a 19-inch rack conforming to EIA standards. Do not use the equipment without a rack or install it on a nonconforming rack. Otherwise, the equipment may not function properly, and there is a risk of equipment damage or personal injury. For suitable racks, contact your sales agent.

Exercise great care not to hurt your fingers on the rail when you mount/dismount the equipment into/from the rack.

!Elevated Operating Ambient Temperature – If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than the room ambient environment. Therefore, consideration should be given to installing the equipment in an environment compatible with the a maximum rated ambient temperature of 35°C. Refer to Chapter 2 on this manual for more details on room ambient temperature.

!Reduced air Flow – Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

!Before pulling a server or device out of a rack, make sure that the rack is secured by stabilizers.

!To prevent fires, and damage to rack equipment and supply wiring, make sure that the rated load of the power branch circuit is not exceeded. Equipment nameplate ratings should be used when addressing this concern. For more information on installation and wiring of power-related facilities, contact your electrician or local power company.

!To prevent electrical shock, connect all rack and rack support equipment to the same electrical circuit of the building wiring. If you are unsure, check the building wiring to avoid remote earth conditions.

!For safe operation, only connect the equipment to a building supply that is in accordance with current wiring regulations in your country. In the U.K., those regulations are the IEE.
