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 x450 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. See 3.2.2, "Remote Expansion Enclosure" on page 51 for RXE-100 cabling information. Since the x450 is rack optimized, the IBM xSeries rack configurator should be used to ensure correct placement.

When the x450 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. Therefore, IBM recommends that the x450 be connected to a 220 V power source to ensure power supply redundancy for large configurations. Tip: If power is not redundant, the non-redundant LED will be lit in the Light Path Diagnostic panel (see 1.10, "Light path diagnostics" on page 25). Two system power-cord connectors are available on the back of the x450, one for each of the power supplies. Connect each of these power connectors to separate power circuits to ensure availability if one circuit should fail. The x450 ships with two 2.8 m/9 ft. IEC 320-C13 to IEC 320-C14 power cables for intra-rack power distribution. Models shipped in the US also include two 2.8 Chapter 3. Planning 63
