Electrostatic Discharge Information
A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper
packaging and grounding techniques are necessary precautions to prevent damage. To prevent
electrostatic damage, observe the following precautions:
■ Transport products in static-safe containers such as conductive tubes, bags, or boxes.
■ Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
■ Cover work stations with approved static-dissipating material. Provide a wrist strap
connected to the work surface and properly grounded tools and equipment.
■ Keep work area free of nonconductive materials such as ordinary plastic assembly aids
and foam packing.
■ Make sure you are always properly grounded when touching a static-sensitive component
or assembly.
■ Avoid touching pins, leads, or circuitry.
■ Always place drives PCB assembly-side down.
■ Use conductive field service tools.

Weight in kg
Weight in lb
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
Removal and Replacement Procedures 2-3
Any product or assembly marked with these symbols indicates that the
component exceeds the recommended weight for one individual to handle
safely.
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 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.
WARNING: To reduce the risk of injury from electric shock, remove all power
cords to completely disconnect power from the system.
2-4 Compaq ProLiant ML370 Maintenance and Service Guide
WARNING: To reduce the risk of personal injury or damage to the equipment: If the server is
mounted in a rack, internal devices may not be accessible for removal and replacement. If the
server must be removed from the rack for device accessibility, remove the server from the rack
and place it on a sturdy table or workbench. Refer to the ProLiant ML370 Servers Setup and
Installation Guide for further information on working with racks.
CAUTION: The system power in the server does not completely shut off from the front Power
On/Standby switch. Moving the switch from On to Standby leaves some portions of the hot-plug
power supply and some internal circuitry active. Disconnect all power cords from the server to
remove all power from the system.
CAUTION: Electrostatic discharge can damage electronic components. Be sure you are
properly grounded before beginning any installation procedure. For more information, see the
section titled “Electrostatic Discharge Information” earlier in this chapter.
To power down the server:
1. Press the Power On/Standby switch to Standby. This places the server in standby mode,
thereby disabling the main power supply output and providing auxiliary power to the
server. Standby does not completely remove power from the system.
2. Verify that the system power LED indicator on the front panel, near the Power
On/Standby switch, is amber and that the fan noise stops.
3. Disconnect all AC power cords from the AC outlet, then from the server.
4. Disconnect all external peripheral devices from the server.
5. For stability and safety, properly positioning the server is critical. If the server is mounted
in a rack, remove the rack model server from the rack and place it on a sturdy table or
workbench. Refer to the ProLiant ML370 Servers Setup and Installation Guide for
instructions.
Rack Warnings
WARNING: To reduce the risk of personal injury, make sure that the rack is adequately
stabilized before extending a component outside the rack. A rack may become unstable if more
than one component is extended for any reason. Extend only one component at a time.
WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:
■ The leveling jacks are extended to the floor.
■ The full weight of the rack rests on the leveling jacks.
■ The stabilizers are attached to the rack if it is a single rack installation.
■ The racks are coupled together in multiple rack installations.
Server Warnings and Precautions
WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.
WARNING: To reduce the risk of electric shock or damage to the equipment:
■ Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
■ Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at
all times.
■ Install the power supply before connecting the power cord to the power supply.
■ Unplug the power cord before removing the power supply from the server.
■ Disconnect power from the server by unplugging the power cord from either the electrical
outlet or the server. If the system has multiple power supplies, disconnect power from the
system by unplugging all power cords from the power supplies.
CAUTION: Protect the server from power fluctuations and temporary interruptions with a
regulating uninterruptible power supply (UPS). This device protects the hardware from damage
caused by power surges and voltage spikes and keeps the system in operation during a power
failure.
Removal and Replacement Procedures 2-5
CAUTION: ProLiant ML370 Servers must always be operated with the system unit cover on.
Proper cooling will not be achieved if the system unit cover is removed.
