System x3650 M3 Types 4255, 7945, and 7949: Installation and User's Guide
Environment:
v Air temperature:
– Server on: 10°C to 35°C (50.0°F to
95.0°F); altitude: 0 to 914.4 m (3000
ft). Decrease system temperature by
1°C for every 1000-foot increase in
altitude.
– Server off: 5°C to 45°C (41.0°F to
113.0°F); maximum altitude: 3048 m
(10000 ft)
– Shipment: -40°C to +60°C (-40°F to
140°F); maximum altitude: 3048 m
(10000 ft)
v Humidity:
– Server on: 20% to 80%; maximum
dew point: 21°C; maximum rate of
change 5°C per hour.
– Server off: 8% to 80%; maximum
dew point: 27°C
– 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
183.

Hot-swap fans: Three - provide redundant
cooling.
Power supply:
v Up to two hot-swap power supplies for
redundancy support
– 460-watt ac
– 675-watt ac
– 675-watt high-efficiency ac
– 675-watt dc
Note: You cannot mix 460-watt and
675-watt power supplies, or high-efficiency
and non-high-efficiency power supplies, or
ac and dc power supplies in the server.
