Preparation Procedures

Before beginning to remove any serviceable parts, determine whether the part is hot-pluggable or non-hot-pluggable.

Hot-Pluggable Devices

Hot-pluggable devices in the ProLiant ML370 Servers include SCSI hard drives and power supplies (with redundant power supply option kit).

IMPORTANT: It is not necessary to turn off the server to replace hot-plug devices when they are not in active use.

Non-Hot-Pluggable Devices

If the part is non-hot-pluggable, the server must be powered down. Non-hot-pluggable parts include the processors, all boards, DIMMs, fans, drive cages, and the standard power supply.

Powering Down the Server

System power in ProLiant ML370 Servers does not completely shut off with the front panel Power On/Standby switch. The switch toggles between On and Standby, rather than On and Off. The standby position removes power from most electronics and the drives, but portions of the hot-plug power supply and some internal circuitry remain active. To completely remove all power from the system, you must disconnect all power cords from the server.

WARNING: To reduce the risk of injury from electric shock, remove all power cords to completely disconnect power from the system.

WARNING: To reduce the risk of personal injury or damage to the equipment, ensure that only one component is extended at a time. A rack may become unstable if more than one component is extended for any reason.

WARNING: Because the rack allows you to stack computer components on a vertical rather than horizontal plane, you must take precautions to provide for rack stability and safety. It is important that you follow these precautions to provide for rack stability and safety and to protect both personnel and property. Heed all cautions and warnings throughout the installation instructions that came with the server.
