IBM 440 manual Power considerations, Click Select a country

￿For thermal considerations, the x440 must be installed with perforated doors on both front and back. Do not install the x440 in a rack with a glass front door.

￿Although installation is supported in non-enterprise racks, it is not recommended, since cable management then becomes an issue.

￿The maximum weight of the system, depending on your configuration, is 50 kg (110 lb.). Therefore, this system requires two people to install it in a rack.

If you use a non-IBM rack, the cabinet must meet the EIA-310-D standards with a depth of at least 28 inches. Also, adequate space (approximately two inches for the front bezel and one inch for air flow) must be maintained from the slide assembly to the front door of the rack cabinet to allow sufficient space for the door to close and provide adequate air flow.

Make sure all the cables attached to the x440 are long enough to permit the server to be slid out of the rack. This would include the normal cables such as power, network, and fiber cables, but also includes the Remote I/O cable for connecting to the RXE-100 and the SMP expansion cables for connecting to another x440. See “Remote Expansion Enclosure” on page 78 for RXE-100 cabling information.

Since the x440 is rack optimized, the IBM xSeries rack configurator should be used to ensure correct placement. The configurator can be downloaded from:

3.8Power considerations

The x440 ships with two redundant, hot-swappable power supplies that produce 1050 W each at 220 V, or 550 W each at 110 V. When the x440 is populated with more than two processors, memory, and adapters, the power supplies may not be redundant if they are connected to a 110 V power source.
