A-Class Server Site Preparation

Overview

This section contains the following environmental requirements for preparing a site for the A-Class Server:

“Space Requirements”. Space requirements for both stand-alone and cabinet-mounted A-Class servers.
“Input Power Requirements”. Nominal input voltage, nominal frequency, and typical current requirements.
“Cooling Requirements”. Operating and non-operating temperature extremes and relative humidity parameters.

Space Requirements

Stand-Alone Server Dimensions

The physical characteristics of the A-Class server are listed as follows:

Dimension
Height	8.89 cm	(3.5 in.)
Width	43.18 cm	(17 in.)
Depth	58.42 cm	(23 in.)
Weight	9.98kg	(22 lbs)

Stand-Alone Server Minimum Service Access Requirements

Access Location
Rear	15 cm	(6 in.)
Sides	7.5 cm	(3 in.)
Front	7.5 cm	(3 in.)




	CAUTION: Stacking A-Class servers in any manner and mounting in any cabinet other than a Hewlett-Packard approved cabinet, is not supported. While they are constructed to be strong, A-Class servers have not been tested for stacking load carrying capacity. Failure to follow this precaution may result in major damage to the server.

Cabinet Dimensions

A-Class servers can be installed in any of the following cabinets:

Cabinet Product Number	Description	EIA	Max. A-Class Servers	External Dimensions (width x depth x height)

C2787A	Field Integrated 2.0m x 19" Cabinet	41	20	61 x 91.4 x 203.2	24 x 36 x 80

Cabinet Minimum Service Access Requirements

Access Location
Rear	61 cm	(24 in.)
Sides	NA	(NA)
Front	100.3	(39.5 in.)

Input Power Requirements

Input power requirements for the A-Class server are listed as follows:

Nominal Input Voltage (VAC): 100 - 240
Nominal Frequency: 50 or 60 Hz
Typical current requirements:
- 1.0A at 100V
- 0.43A at 240V.

If an Uninterruptible Power Supply (UPS) is to be used, ensure that it is properly connected to the server. Refer to the, “External Connections” section for UPS information.

Power cord plugs for stand-alone servers are configured to meet unique power configurations used all over the world.

Cabinet-mounted servers have the same power requirements as stand-alone servers. However, the power cords for cabinets are dependent on the type of Power Distribution Unit (PDU) operation.

PDU power cords with one end stripped are also available for attaching country-specific power plugs. Refer to the cabinet documentation for more electrical power information.
