SAN Volume Controller 2145-DH8 environment requirements

Edit online

Before the SAN Volume Controller 2145-DH8 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
100-127 / 200-240Vac 50 Hz or 60 Hz

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. Power consumption
Components Power requirements
SAN Volume Controller 2145-DH8 200 W typical, 750 W maximum (200 - 240V ac, 50/60 Hz)
Note: You cannot mix ac and dc power sources; the power sources must match.

Environment requirements without redundant AC power

Ensure that your environment falls within the following ranges if you are not using 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. Physical specifications
Environment Temperature Altitude Relative humidity Maximum dew point
Operating in lower altitudes 5°C to 40°C
(41°F to 104°F)		 0 to 950 m
(0 ft to 3,117  ft)
 8% to 85% 24°C (75°F)
Operating in higher altitudes 5°C to 28°C
(41°F to 82°F)		 951 m to 3,050 m
(3,118  ft to 10,000 ft)
Turned off (with standby power) 5°C to 45°C
(41°F to 113°F)		 0 m to 3,050 m
(0 ft to 10,000 ft)		 8% to 85% 27°C (80.6°F)
Storing 1°C to 60°C
(33.8°F to 140.0°F)		 0 m to 3,050 m
(0 ft to 10,000 ft)		 5% to 80% 29°C (84.2°F)
Shipping -40°C to 60°C
(-40°F to 140.0°F)		 0 m to 10,700 m
(0 ft to 34,991 ft)		 5% to 100% 29°C (84.2°F)
Note: Decrease the maximum system temperature by 1°C for every 175 m increase in altitude.

Preparing your environment

The following tables list the physical characteristics of the 2145-DH8 node.

Dimensions and weight

Use the parameters that are shown in Table 4 to ensure that space is available in a rack capable of supporting the node.

Table 4. Dimensions and weight
Height Width Depth Maximum weight
86 mm (3.4 in.) 445 mm (17.5 in) 746 mm (29.4 in) 25 kg (55 lb) to 30 kg (65 lb) depending on configuration

Additional space requirements

Ensure that space is available in the rack for the additional space requirements around the node, as shown in Table 5.

Table 5. 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

Maximum heat output of each 2145-DH8 node

The node dissipates the maximum heat output that is given in Table 6.

Table 6. Maximum heat output of each 2145-DH8 node
Model Heat output per node
2145-DH8
  • Minimum configuration: 419.68 Btu per hour (AC 123 watts)
  • Maximum configuration: 3480.24 Btu per hour (AC 1020 watts)
