Specifications
Operating temperature: 5°C to 40°C (41°F to 104°F) (ASHRAE Class
A3 compliant)
Storage temperature: –40°C to +65°C (–40°F to +149°F)
Temperature change rate: < 20°C/h (36°F/h)
Long-term storage temperature: 21°C to 27°C (69.8°F to 80.6°F)
NOTE
l When NVIDIA Tesla P4 GPUs are configured, the maximum operating
temperature is 30°C.
l The 5288 V3 supports the maximum operating temperature of 35°C (95°F)
when it is equipped with rear hard disks, 135 W CPUs, or Huawei PCIe
SSDs.
l The operating performance of hard disks may deteriorate when a single fan
module fails.
l The 5288 V3 can work at the highest temperature of 40°C (86°F) when it
is configured with E5-2698 v3, E5-2690 v3, E5-2667 v3, E5-2643 v3,
E5-2637 v3, E5-2698 v4, E5-2690 v4, E5-2667 v4, E5-2643 v4, or
E5-2637 v4 CPUs. If the environment temperature is over 40°C (86°F) or
one fan fails, CPU performance may deteriorate.
The system draws cool air in from the front, delivers the cool air
through the hard disks, fan modules, processors, dual in-line memory
modules (DIMMs), and PCIe cards, and then exhausts air from the
rear.
Operating humidity: 8% RH to 90% RH (non-condensing)
Storage humidity: 5% RH to 95% RH (non-condensing)
Humidity change rate: < 20% RH/h
Long-term storage humidity: 30% RH to 69% RH
≤ 3048 m (9999.88 ft)
l When the altitude is higher than 900 m (2952.72 ft), the operating
temperature decreases by 1°C (1.8°F) as the altitude increases by
300 m (984.24 ft).
l At an altitude of over 3000 m (9842.5 ft), only Titanium PSUs can
be used.
l HDDs are not supported at an altitude of over 3000 m (9842.5 ft).
