Removal and Replacement Procedures 2-3
Weight in kg
Weight in lb
Any product or assembly marked with these symbols indicates that the
component exceeds the recommended weight for one individual to handle
safely.
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.
