IBM AA-RWF3A-TE manual Environmental requirements

Environmental requirements

To ensure proper operation, the switch must not be subjected to environmental conditions beyond those for which it was tested. The ranges specified in Table 25 list the acceptable environment for both operating and non-operating conditions.

Table 25 Environmental requirements

Condition	Acceptable range during operation		Acceptable range during
			non-operation
Ambient	0° to 40° Celsius (32° to 104°		-25° to 70° Celsius (-13° to 158°
temperature	Fahrenheit)		Fahrenheit)
Humidity	10% to 85% RH non-condensing, at		10% to 90% RH non-condensing, at
	40° Celsius (104° Fahrenheit) , with		70° Celsius (158° Fahrenheit)
	maximum gradient of 10% per hour
Altitude	3,000 meters (9,842 feet) above sea		0 to 12 kilometers (39,370 feet) above
	level		sea level
Shock	20 G, 6 ms duration, half-sine wave		Half sine, 33G 11ms, 3/eg Axis
Vibration	0.5 G sine, 0.4 grms random, 5-500 Hz		2.0 G sine, 1.1 grms random 5-500
			Hz
Airflow for 4/32	24 cubic ft/minute		None required
SAN Switch
Airflow for 4/8,	47 cubic ft/minute		None required
4/16, and 4/64
SAN Switches
Airflow for 4/32B	High speed,	9300 RPM,	None required
SAN Switch	20.8 cubic	feet/ minute
	Low speed, 7200 RPM, 15.4 cubic feet/
	minute

NOTE:

The –10 ºC to +40 ºC range applies to the ambient air temperature at the air intake vents on the nonport side of the switch. The temperature inside the switch can be up to 75 ºC during switch operation.

If the internal temperature range exceeds the operating ranges of the components, the LEDs, error messages, and Fabric Watch alerts will indicate a problem. Issue the tempshow command to view temperature status.
