To rackmount a server, you need to:
■Prepare the rack enclosure—page 1-7
■Prepare the server chassis—page 1-7
■Install the slide assemblies in the rack enclosure—page 1-18
■Install the server into the rack enclosure—page 1-25
Before You Begin
■Read the rack enclosure requirements—page 1-3
■Verify the rackmounting kit contents—page 1-5
■Locate a Phillips #2 screwdriver and a flat-blade screwdriver.

Caution – The chassis is heavy. In the following procedures, two people are
required to move the chassis. Two people are also required to align and install the
slide assemblies in the rack.
Caution – For proper ventilation, each Sun Enterprise 250 server in the rack
enclosure requires 28 square inches (175 square cm) of unrestricted airflow into the
front of the system, and 23 square inches (143 square cm) of unrestricted exhaust
port at the rear of the system. Maintain a minimum 1.5 inches (3.8 cm) clearance
between the system and any front or rear doors.

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.
Rack Enclosure Feature Requirement
Load Bearing Capacity 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.
Vertical Space Requirements 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.
Vertical Mounting Rail
Requirements 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.
Doors If you are using a Sun Enterprise Expansion Cabinet, remove the
front door; otherwise, see the instructions provided with the rack
enclosure.

EMI Requirements Electromagnetic interference (EMI) shielding requirements are met
by the system chassis and metal side panels, which remain in place
when the unit is rackmounted.
Anti-Tip Protection The rack must be bolted securely to the floor or equipped with a
sturdy and extendable anti-tip leg. You must prevent the cabinet
from tipping forward when one or more Sun Enterprise 250 servers
and other devices are fully extended out the front of the rack.
Minimum Service Access An area not less than 3 feet (1 meter) deep and 6 feet (2
meters) wide must be available in front of the rack for
installation and service access.
When fully extended on its mounting rail slides, the system will
protrude 29.75 inches (75.6 cm) forward of the rack’s front vertical
mounting rails.
Fire Containment The rack enclosure must meet Underwriters Laboratories, Inc. and
TUV Rheinland of N.A. requirements for fire containment.
