1.5.1 Enterprise 6500/5500 Cabinet Systems
■
Server cabinets require approximately 4 feet (120 cm) of space in front and 3 feet
(90 cm) in back (
FIGURE 1-5
) for access by service personnel.
■
Server and expansion cabinets can be placed next to each other, without space
between them, since there are no side clearance requirements during operation.
To access and remove side panels, however, allow approximately 1 foot (30 cm) of
space on the sides.
■
The server system (including expansion cabinets) should have a dedicated AC
breaker panel. The server system should not share this breaker panel with other,
unrelated equipment.
■
Keep power and interface cables out of the way of foot traffic. Cables can be
routed inside walls, floors, ceilings, or in protective channels. Interface cables
should be routed away from motors and other sources of electric/magnetic or
radio frequency interference.
■
If the cabinet is installed on a raised floor, conditioned air should be directed to
the bottom of each rack through perforated panels.
■
Refer to the Sun Microsystems Data Center Site Planning Guide, Data Centers’ Best
Practices (805-5863) for more information on the recommended optimal operating
environment.
