You can install the EXP300 expansion unit in the following types of enclosures:
• An Electronic Industries Association (EIA) 310 standard rack cabinet
• The IBM Netfinity EXP300 Rack-to-Tower Conversion Kit
• An IBM Netfinity NetBAY enclosure
You will need a flat-blade screwdriver and a Phillips-head screwdriver to install your
expansion unit. Each type of enclosure comes with general installation instructions
for installing optional devices.
The following table summarizes the operating specifications of the expansion unit.
Environment
• Air temperature:
— Expansion unit on: 10 °
— Expansion unit on: 10 °
• Humidity: 8% to 80%

• Height: 12.8 cm (5 in)
• Width: 44.7 cm (17.6 in)
Weight
• Standard expansion unit as
shipped: 22.5 kg (49.5 lbs)

to 35 ° C (50 ° to 95 ° F)
Altitude: 0 to 914 m
(3000 ft)
to 32 ° C (50 ° to 90 ° F)
Altitude: 914 m (3000 ft.)
to 2133 m (700 ft)
Acoustical noise emissions values
For open bay (no drives installed)
and maximum system
configurations (14 hard disk drives
installed).
• Sound power (idling):
— 5.6 bels (open bay)
— 5.7 bels (typical)
• Sound power (operating):
— 5.6 bels (open bay)
— 6.5 bels (typical)
• Sound pressure (idling):
— 44 dBA (open bay)
— 47 dBA (typical)
• Sound pressure (operating):
— 44 dBA (open bay)
— 54 dBA (typical)
These levels are measured in
controlled acoustical
environments according to ISO
7779 and are reported in
accordance with ISO 9296. The
declared sound power levels
indicate an upper limit, below
which a large portion of machines
operate. Sound pressure levels in
your location might exceed the
average 1-meter values stated
because of room reflections and
other nearby noise.
