52 Sun Fire V440 Server Installation Guide • July 2003
4-Post Cabinet Requirements
The server is designed so that you can install it into a 72-inch (184-cm) tall Sun
StorEdge Expansion cabinet or other EIA-compliant industry-standard cabinet that
meets the requirements listed in the following table. You need a Sun rackmounting
kit for each server that you rackmount.
Note – The server is fully serviceable in a 4-post cabinet when it is extended on its
slide assemblies.
TABLE A-4 4-Post Cabinet Requirements
Cabinet Feature Requirement
Load-bearing capacity The rack must firmly support the weight of as many Sun
Fire V440 servers installed in the cabinet (each server
weighs up to 82 lb/37.2 kg), plus the weight of the
rackmounting hardware, and the weight of any other
installed devices.
Vertical space requirements Each server requires four rack units (7.0 inch/17.78 cm)
of vertical space for rack installation. A 72-inch (184-cm)
Sun cabinet ships with a power sequencer so it can
nominally hold up to eight servers (with a power
sequencer there are 36 rack units of usable space).
However, because of electrical power issues, the actual
maximum of systems per rack is six.
Doors and panels If you are using a Sun StorEdge Expansion Cabinet, you can
remove the front and back doors and the side panels to
increase access to the server. Otherwise, see the instructions
provided with the cabinet.
Anti-tip protection The cabinet must be bolted securely to the floor or equipped
with two sturdy and extendable anti-tip legs. You must
prevent the cabinet from tilting forward when one or more
servers or devices are fully extended out the front of the
cabinet.
