WARNING
To avoid a risk of injuries, users should not attempt to inst all the equipment into a
rack. Installation should be performed by trained mainte nance 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 s tabilizers.
For stability and to distribute the weight, attach stabili zers or install two or more
racks together. Otherwise, the rack may topple over and c ause 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 sam e 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 EI A standards. Do not use
the equipment without a rack or install it on a nonconf orming 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 a gent.
Exercise great care not to hurt your fingers on the rail wh en 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.
