SAN Volume Controller 2145-CG8 environment requirements

Before the SAN Volume Controller 2145-CG8 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.

Input-voltage requirements

Ensure that your environment meets the voltage requirements that are shown in Table 1.

Table 1. Input-voltage requirements
Voltage	Frequency
200 V - 240 V single phase ac	50 Hz or 60 Hz

Attention:

If the uninterruptible power supply is cascaded from another uninterruptible power supply, the source uninterruptible power supply must have at least three times the capacity per phase and the total harmonic distortion must be less than 5%.
The uninterruptible power supply also must have input voltage capture that has a slew rate of no more than 3 Hz per second.

Maximum power requirements for each node

Ensure that your environment meets the power requirements as shown in Table 2.

The maximum power that is required depends on the node type and the optional features that are installed.

Table 2. Maximum power consumption
Components	Power requirements
SAN Volume Controller 2145-CG8 and 2145 UPS-1U	200 W

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

For the high-speed SAS adapter with from one to four solid-state drives, add 50 W to the power requirements.

Circuit breaker requirements

The 2145 UPS-1U has an integrated circuit breaker and does not require additional protection.

Environment requirements without redundant AC power

If you are not using redundant ac power, ensure that your environment falls within the ranges that are shown in Table 3.

Table 3. Environment requirements without redundant AC power
Environment	Temperature	Altitude	Relative humidity	Maximum wet bulb temperature
Operating in lower altitudes	10°C - 35°C (50°F - 95°F)	0 m - 914 m (0 ft - 3000 ft)	8% - 80% noncondensing	23°C (73°F)
Operating in higher altitudes	10°C - 32°C (50°F - 90°F)	914 m - 2133 m (3000 ft - 7000 ft)	8% - 80% noncondensing	23°C (73°F)
Turned off	10°C - 43°C (50°F - 109°F)	0 m - 2133 m (0 ft - 7000 ft)	8% - 80% noncondensing	27°C (81°F)
Storing	1°C - 60°C (34°F - 140°F)	0 m - 2133 m (0 ft - 7000 ft)	5% - 80% noncondensing	29°C (84°F)
Shipping	-20°C - 60°C (-4°F - 140°F)	0 m - 10668 m (0 ft - 34991 ft)	5% - 100% condensing, but no precipitation	29°C (84°F)

Environment requirements with redundant AC power

If you are using redundant ac power, ensure that your environment falls within the ranges that are shown in Table 4.

Table 4. Environment requirements with redundant AC power
Environment	Temperature	Altitude	Relative humidity	Maximum wet bulb temperature
Operating in lower altitudes	15°C - 32°C (59°F - 90°F)	0 m - 914 m (0 ft - 3000 ft)	20% - 80% noncondensing	23°C (73°F)
Operating in higher altitudes	15°C - 32°C (59°F - 90°F)	914 m - 2133 m (3000 ft - 7000 ft)	20% - 80% noncondensing	23°C (73°F)
Turned off	10°C - 43°C (50°F - 109°F)	0 m - 2133 m (0 ft - 7000 ft)	20% - 80% noncondensing	27°C (81°F)
Storing	1°C - 60°C (34°F - 140°F)	0 m - 2133 m (0 ft - 7000 ft)	5% - 80% noncondensing	29°C (84°F)
Shipping	-20°C - 60°C (-4°F - 140°F)	0 m - 10668 m (0 ft - 34991 ft)	5% - 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-CG8 node.

Dimensions and weight

Use the parameters that are shown in Table 5 to ensure that space is available in a rack capable of supporting the node.

Table 5. Dimensions and weight
Height	Width	Depth	Maximum weight
4.3 cm (1.7 in.)	44 cm (17.3 in.)	73.7 cm (29 in.)	15 kg (33 lb)

Additional space requirements

Ensure that space is available in the rack for the additional space requirements around the node, as shown in Table 6.

Table 6. Additional space requirements
Location	Additional space requirements	Reason
Left side and right side	Minimum: 50 mm (2 in.)	Cooling air flow
Back	Minimum: 100 mm (4 in.)	Cable exit
