Inlet temp on HP Enclosure c7000

[chuckk281]

Jonathan had a inlet temp cooling question:

*********************

Trouble you on this query

Equipment is c7000 which is front to back cooling

Customer inlet temperature is 25 degress, is this supported?

QuickSpecs say yes.

Temperature Range

Operating

50° to 95° F (10° to 35° C)

Non-Operating

-22° to 140° F (-30° to 60° C)

Relative Humidity

Operating

10 to 90% relative humidity (Rh), 28°C (82.4°F) maximum wet bulb temperature, non-condensing.

Non-Operating

5 to 95% relative humidity (Rh), 38.7°C (101.7°F)maximum wet bulb temperature, non-condensing.

NOTE: Operating temperature has an altitude derating of 1.8° F (1° C) per 1,000 ft (304.8 m). No direct sunlight. Upper operating limit is 10,000 ft (3,048 m) or 70Kpa/10.1 psia. Upper non-operating limit is 30,000 ft (9,144 m) or 30.3 KPa/4.4 psia. Storage maximum humidity of 95% is based on a maximum temperature of 113° F (45° C). Altitude maximum for storage is 70 KPa.

Anyone run into temp issues with running the c7000 chassis?

just additional note to explain the behaviour of a empty C-class enclosure regarding the FANs. If there are 0 (zero) blades installed inside a C7000/C3000 encl. then the OA cannot use the normal ambient inlet temp. of the blades to control the right FAN speed per fanzone; for that reason it can with a empty enclosure on use its own ambient inlet temp. sensor that is placed at the OA module (tray); for that reason the FAN speed of a empty enclosure might be higher as expected until a blade server is inserted; then the OA will start to use that server his ambient inlet temp. as reference.
