Table 31. Gaseous contamination specifications
Gaseous contamination Specifications
Copper coupon corrosion rate <300 Å/month per Class G1 as defined by ANSI/
ISA71.04-1985.
Silver coupon corrosion rate <200 Å/month as defined by AHSRAE TC9.9.
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.
Standard operating temperature
Table 32. Standard operating temperature specifications
Standard operating temperature Specifications
Temperature ranges (for altitude less than 950 metres or 3117
feet)
10°C to 35°C (50°F to 95°F) with no direct sunlight on the
equipment.
NOTE: Maximum of 145 W 22–core processor is
supported in systems with eight 2.5-inch drives 2–PCI slot
chassis, and 75 W single wide active GPU.
Standard operating temperature restrictions
● Ambient temperature is restricted to 30°C for systems
with eight 2.5-inches drives or ten 2.5-inch drives chassis,
with no PCIe SSD and a maximum of 160 W workstation
processor.
● Ambient temperature is restricted to 30°C for systems
with ten 2.5-inch drives chassis, PCIe SSD and a maximum
of 135 W processor.
● Ambient temperature is restricted to 35°C for systems
with ten 2.5-inch drives chassis, PCIe SSD and a maximum
of 120 W processor.
● Ambient temperature is restricted to 35°C for systems
with twenty-four 1.8-inch drives chassis, PCIe SSD, and a
maximum of 135 W processor.
Expanded operating temperature
Table 33. Expanded operating temperature specifications
Expanded operating temperature Specifications
Continuous operation 5°C to 40°C at 5% to 85% RH with 29°C dew point.
NOTE: Outside the standard operating temperature
(10°C to 35°C), the system can operate continuously in
temperatures as low as 5°C and as high as 40°C.
For temperatures between 35°C and 40°C, de-rate maximum
allowable temperature by 1°C per 175 m above 950 m (1°F
per 319 ft).
≤ 1% of annual operating hours –5°C to 45°C at 5% to 90% RH with 29°C dew point.
NOTE: Outside the standard operating temperature (10°C
to 35°C), the system can operate down to –5°C or up to
45°C for a maximum of 1% of its annual operating hours.
For temperatures between 40°C and 45°C, de-rate maximum
allowable temperature by 1°C per 125 m above 950 m (1°F
per 228 ft).
NOTE: When operating in the expanded temperature range, system performance may be impacted.
