Connecting And Disconnecting Power To Hot-Pluggable Power Supplies; Rack-Mountable Components - HP MCS Manual

Connecting and disconnecting power to hot-pluggable power supplies

Observe the following guidelines when connecting and disconnecting power to the power supplies:
• Unplug the power cord before removing the power supply from the server.
• Install the power supply before connecting the power cord to the power supply.
• Do not overload the AC supply branch circuit that provides power to the HP MCS. The total HP
MCS load should not exceed 80 percent of the branch circuit rating.

Rack-mountable components

Because computer components are stacked vertically in an HP MCS, adhere to the following
precautions to ensure HP MCS stability:
• Load heavier components first and load the HP MCS from the bottom up.
• Allow a minimum clearance of 30 in. (762 mm) at the back of the HP MCS.
• Allow a minimum of 48 in. (1219.2 mm) clearance beyond the front of the HP MCS to permit
server installation and removal. This applies to both individual HP MCS installations as well as
when aligning HP MCSs in rows so that the front doors are facing each other. See Figure 4.
• Use caution when pressing the component rail release latches and sliding a component into the HP
MCS. The slide rails can pinch your fingers and cables.

Warning:
To reduce the risk of personal injury or damage to the equipment, be sure
that the HP MCS is stabilized as follows:
•
The leveling feet are extended to the floor.
•
The full weight of the HP MCS rests on the leveling feet.
•
Extend only one component at a time or the HP MCS may become unstable.
