Sun Fire V490 Server Setup and Rackmounting Guide • August 2004
Note –
The system is fully serviceable in a 4-post cabinet when it is extended on its
slide assemblies.
TABLE A-1
4-Post Rack Requirements
Cabinet Feature
Requirement
Load-bearing capacity
The rack must firmly support the weight of as many
Sun Fire V490 servers as you are installing into the
cabinet (each server weighs up to 97 lb/44 kg), plus
the weight of the rackmounting hardware, and the
weight of any other installed devices.
Vertical space requirements
Each server requires five rack units (8.75 in/22.22 cm) of
vertical space for rack installation. A 72-inch (184-cm) Sun
cabinet ships with a power sequencer so that it can hold up
to seven servers (with a power sequencer there are 36 rack
units of usable space).
Note:
If the servers are fully
populated, the cabinet and power sequencer will only
support six servers. See the
Site Planning Guide for Entry-
Level Servers Version 1.5
for more information.
Doors and panels
If you are using a Sun expansion cabinet, you can remove
the front and back doors and the side panels to increase
access to the system. 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
systems or devices are fully extended out the front of the
cabinet.
