Specifications
● 460 W, 750 W or 1200 W AC PSUs: 100 V to 240 V AC
● 460 W, 750 W or 1200 W AC PSUs (compatible with 240 V
HVDC PSUs): 192 V to 288 V DC
● 800 W DC PSUs: –36 V to –75 V DC
● 1200 W high-voltage direct current (HVDC) PSUs: 260 V
to 400 V DC
NOTE
The recommended current specification for the external power circuit
breaker connected to the RH2288H V3 is 32 A.
● Operating temperature: 5°C to 45°C (41°F to 113°F)
(ASHRAE Classes A2 to A4 compliant)
● Storage temperature (within three months): –30°C to
+60°C (–22°F to +140°F)
● Storage temperature (within six months): –15°C to +45°C
(5°F to 113°F)
● Storage temperature (within one year): –10°C to +35°C
(14°F to 95°F)
● Maximum rate of temperature change: 20°C (36°F) per
hour, 5°C (9°F) per 15 minutes
NOTE
● When PCIe SSD cards or NVMe PCIe SSDs are used, the RH2288H
V3 supports the maximum operating temperature of 35°C (95°F)
and the failure of one fan may result in performance
deterioration.
● The RH2288H V3 supports the maximum operating temperature
of 35°C (95°F) when it is equipped with rear drives.
● When M60 GPUs are configured, the maximum operating
temperature is 30°C.
● When NVIDIA Tesla P4 GPUs are configured, the maximum
operating temperature is 35°C.
● The RH2288H V3 can work at the highest temperature of 40°C
(104°F) when it is configured with E5-2699 v3, E5-2698 v3,
E5-2697 v3, E5-2690 v3, E5-2667 v3, E5-2643 v3, E5-2637 v3,
E5-2699A v4, E5-2699 v4, E5-2698 v4, E5-2697A v4, E5-2697 v4,
E5-2690 v4, E5-2667 v4, E5-2643 v4, or E5-2637 v4 CPUs. If the
environment temperature is over 40°C (104°F) or one fan fails,
CPU performance may deteriorate.
● When GPUs of 200 W or higher are used, the RH2288H V3
supports the maximum operating temperature of 35°C (95°F) and
a maximum of eight front drives. When K80 and P100 GPUs are
used, the RH2288H V3 supports the maximum operating
temperature of 30°C (86°F). The failure of one fan may result in
GPU performance deterioration.
The system draws cool air in from the front, delivers the cool
air through the drives, fan modules, CPUs, DIMMs, and PCIe
cards, and then exhausts air from the rear.
