(28.2 lb) for a standard unit; when
fully configured, 15.4 kg
(33.9 lb)
Environment:
v
Air temperature:
– Enclosure on: 10° to 35°C (50°
to 95°F); altitude: 0 to 914.4 m
(3000 ft). Decreased system
temperature by 0.75° for every
1000 ft. increase in altitude.

113`°F)
– Shipment: -40°C to +60°C
(-40°F to 140°F
v Humidity:
– Enclosure on: 20% to 80%;
maximum dew point: 21°C
(70°F)
– Enclosure off: 8% to 80%;
maximum dew point: 27°C
(80°F)
– Shipment: 5% to 100%
v
Particulate contamination:
Attention: Airborne particulates
and reactive gases acting alone or
in combination with other
environmental factors such as
humidity or temperature might pose
a risk to the server. For information
about the limits for particulates and
gases, see “Particulate
contamination” on page 105.
Heat output
Approximate heat:
v Minimum configuration: 314 Btu
per hour (92 watts)
v Maximum configuration 2048 Btu
per hour (600 watts)
Electrical input:
v Sine-wave input (50 - 60 Hz)
required
v Input voltage low range:
– Minimum: 90 V ac
– Maximum: 136 V ac
v
Input voltage high range:
– Minimum: 198 V ac
– Maximum: 264 V ac
v
Approximate input kilovolt-amperes
(kVA):
– Minimum: 0.1 kVA
– Maximum: 0.6 kVA
Notes:
1. Power consumption and heat
output vary depending on the
number and type of optional
features that are installed and the
power-management optional
features that are in use.
2. These levels were measured in
controlled acoustical environments
according to the procedures
specified by the American
National Standards Institute
(ANSI) S12.10 and ISO 7779 and
are reported in accordance with
ISO 9296. Actual sound-pressure
levels in a given location might
exceed the average stated values
because of room reflections and
other nearby noise sources. The
declared sound-power levels
indicate an upper limit, below
which a large number of
computers will operate.
What the MAX5 offers
The IBM MAX5 for System x (MAX5) memory expansion module provides several
features for easy operation, including the following features:
v
Customer replaceable units (CRUs)
The major CRUs in the MAX5 expansion module are memory modules, fans, and
power supplies. See “MAX5 components” on page 72 for the supported MAX5
components.
v
Light path diagnostics LEDs
The MAX5 expansion module has light path LEDs (front and rear) to indicate
hardware, scaling, and power problems.
