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-44-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.
