Rack Enclosure Requirements

The Sun Enterprise 250 server is designed so that you can install it into a
Sun 56-inch (143-cm) tall Enterprise Expansion cabinet or other suitable
industry-standard rack enclosure that meets the requirements listed in the
table below. You need a Sun rackmounting kit for each server that you will
rackmount.

Requirement
The rack must firmly support the weight of an Sun Enterprise 250
server (118 lbs, 53 kg), plus the weight of the rackmounting
hardware, plus the weight of any other installed devices.
Each Sun Enterprise 250 server requires six rack units (10.5
inches, 26.7 cm) of vertical space for rack installation. A 56-
inch (143-cm) cabinet can accommodate up to four Sun
Enterprise 250 servers; a 68-inch (173-cm) and a 72-inch (183-
cm) cabinet can hold up to five servers.
The rack must have two pairs of vertical mounting rails (one pair
in front, one in back) that conform to the EIA (RETMA) standard
for mounting hole spacing.
Left-side-to-right-side rail spacing (mounting hole center to
mounting hole center) for front and rear rails must be 18.3 inches
(46.5 cm).
Front-to-rear rail spacing must be at least 26.875 inches (68.26 cm)
and not more than 34.875 inches (88.5 cm) from the outside face of
the front rail to the outside face of the rear rail.
Front and rear vertical rail mounting faces must be parallel with
each other and with the front plane of the rack.
The Sun Enterprise 250 server will extend 2.3 inches (5.84 cm)
forward of the front vertical mounting rails, and the enclosure
extends 28.25 inches (71.76 cm) from the front face to the rear-
most point.
If you are using a Sun Enterprise Expansion Cabinet, remove the
front door; otherwise, see the instructions provided with the rack
enclosure.
