Altitude
0 m to 3048 m (0 ft to 10 000 ft) in an unpressurized environment
Note:
When the altitude exceeds 900 m (2953 ft), the defined maximum dry-bulb
temperature for operation becomes a dependent variable.
A2: The temperature value decreases by 1°C (33.8°F) with every 300 m (984 ft) of
altitude increase.
A3: The temperature value decreases by 1°C (33.8°F) with every 175 m (574 ft) of
altitude increase.
B: The temperature value decreases by 1°C (33.8°F) with every 300 m (984 ft) of altitude
increase.
Note:
Ensure that the ambient temperature does not exceed 35°C (95°F) and all system fans are working
properly. If a system fan fails, turn off the server immediately and replace the system fan as soon as possible
to avoid system failure or data loss. To replace a system fan, refer to “Front system fan” on page 90 and
“Rear system fan” on page 92.
