SAN Volume Controller 2145-4F2 environment requirements

Before the SAN Volume Controller 2145-4F2 is installed, the physical environment must meet certain requirements. This includes verifying that adequate space is available and that requirements for power and environmental conditions are met. The SAN Volume Controller 2145-4F2 node is supported only in SAN Volume Controller 4.3.1 and earlier releases.

Input-voltage requirements

Ensure that your environment meets the following voltage requirements.

Voltage	Frequency
200 to 240 V single phase ac	50 or 60 Hz

Power requirements for each node

Ensure that your environment meets the following power requirements.

The power that is required depends on the node type and whether the redundant ac power feature is used.

Components	Power requirements
SAN Volume Controller 2145-4F2 and 2145 UPS-1U	420 W
One SAN Volume Controller 2145-4F2 and one 2145 UPS	760 W
Two SAN Volume Controller 2145-4F2 nodes and one 2145 UPS	1120 W

For each redundant ac-power switch, add 20 W to the power requirements.

Circuit breaker requirements

Ensure that the following circuit breaker requirements are met:

The 2145 UPS-1U has an integrated circuit breaker and does not require additional protection.
Each 2145 UPS is connected to a separate branch circuit, which includes a UL-listed 15 A circuit breaker.

Environment requirements without redundant ac power

Ensure that your environment falls within the following ranges if you are not using redundant ac power.

Environment	Temperature	Altitude	Relative humidity	Maximum wet bulb temperature
Operating in lower altitudes	10°C to 35°C (50°F to 95°F)	0 to 914.4 m (0 to 3000 ft)	8% to 80% noncondensing	23°C (74°F)
Operating in higher altitudes	10°C to 32°C (50°F to 88°F)	914.4 to 2133.6 m (3000 to 7000 ft)	8% to 80% noncondensing	23°C (74°F)
Turned off	10°C to 43°C (50°F to 110°F)	0 to 2133.6 m (0 to 7000 ft)	8% to 80% noncondensing	27°C (81°F)
Storing	1°C to 60°C (34°F to 140°F)	0 to 2133.6 m (0 to 7000 ft)	5% to 80% noncondensing	29°C (84°F)
Shipping	-20°C to 60°C (-4°F to 140°F)	0 to 10668 m (0 to 34991 ft)	5% to 100% condensing, but no precipitation	29°C (84°F)

Environment requirements with redundant ac power

Ensure that your environment falls within the following ranges if you are using redundant ac power.

Environment	Temperature	Altitude	Relative humidity	Maximum wet bulb temperature
Operating in lower altitudes	15°C to 32°C (59°F to 89°F)	0 to 914.4 m (0 to 3000 ft)	20% to 80% noncondensing	23°C (74°F)
Operating in higher altitudes	15°C to 32°C (50°F to 88°F)	914.4 to 2133.6 m (3000 to 7000 ft)	20% to 80% noncondensing	23°C (74°F)
Turned off	10°C to 43°C (50°F to 110°F)	0 to 2133.6 m (0 to 7000 ft)	20% to 80% noncondensing	27°C (81°F)
Storing	1°C to 60°C (34°F to 140°F)	0 to 2133.6 m (0 to 7000 ft)	5% to 80% noncondensing	29°C (84°F)
Shipping	-20°C to 60°C (-4°F to 140°F)	0 to 10668 m (0 to 34991 ft)	5% to 100% condensing, but no precipitation	29°C (84°F)

Preparing your environment

The following tables list the physical characteristics of the SAN Volume Controller 2145-4F2 node.

Dimensions and weight

Ensure that space is available in a rack that is capable of supporting the node.

Height	Width	Depth	Maximum weight
43 mm (1.69 in.)	440 mm (17.32 in.)	686 mm (27 in.)	12.7 kg (28 lb)

Additional space requirements

Ensure that space is also available in the rack for the following additional space requirements around the node.

Location	Additional space requirements	Reason
Left and right sides	50 mm (2 in.)	Cooling air flow
Back	Minimum: 100 mm (4 in.)	Cable exit

Heat output of each SAN Volume Controller 2145-4F2 node

The node dissipates the following maximum heat output.

Model	Heat output per node
SAN Volume Controller 2145-4F2	350 W (1200 Btu per hour)
