Safety considerations
Before performing service procedures, review all the safety information.
Preventing electrostatic discharge
To prevent damaging the system, be aware of the precautions you need to follow
when setting up the system or handling parts. A discharge of static electricity
from a finger or other conductor may damage system boards or other staticsensitive devices. This type of damage may reduce the life expectancy of the
device.
To prevent electrostatic damage:
• Avoid hand contact by transporting and storing products in static-safe
containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-
free workstations.
• Place parts on a grounded surface before removing them from their
containers.
• Avoid touching pins, leads, or circuitry.
• Always be properly grounded when touching a static-sensitive component or
assembly.
Server warnings and cautions
Before installing a server, be sure that you understand the following warnings
and cautions.
WARNING: To reduce the risk of electric shock or damage to
the equipment:
Removal and replacement procedures 13
• 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.
• Unplug the power cord from the power supply to disconnect
power to the equipment.
• Do not route the power cord where it can be walked on or
pinched by items placed against it. Pay particular attention to
the plug, electrical outlet, and the point where the cord extends
from the server.
WARNING: To reduce the risk of personal injury from hot
surfaces, allow the drives and the internal system components to
cool before touching them.
CAUTION: Do not operate the server for long periods with the
access panel open or removed. Operating the server in this manner
results in improper airflow and improper cooling that can lead to thermal
damage.
Warnings and cautions
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 stabilizing feet are attached to the rack if it is a single-rack
installation.
• The racks are coupled together in multiple-rack installations.
• Only one component is extended at a time. A rack may become
unstable if more than one component is extended for any
reason.
WARNING: To reduce the risk of personal injury or equipment
damage when unloading a rack:
14 HP ProLiant ML310 Generation 2 Server Maintenance and Service Guide
• At least two people are needed to safely unload the rack from
the pallet. An empty 42U rack can weigh as much as 115 kg
(253 lb), can stand more than 2.1 m (7 ft) tall, and may become
unstable when being moved on its casters.
• Never stand in front of the rack when it is rolling down the ramp
from the pallet. Always handle the rack from both sides.
WARNING: When installing a server in a telco rack, be sure
that the rack frame is adequately secured to the top and bottom of
the building structure.
WARNING: This server is very heavy. To reduce the risk of
personal injury or damage to the equipment:
• Observe local occupational health and safety requirements and
guidelines for manual material handling.
• Get help to lift and stabilize the product during installation or
removal, especially when the product is not fastened to the
rails. When the server weighs more than 22.5 kg (50 lb), at least
two people must lift the server into the rack together. A third
person may be required to help align the server if the server is
installed higher than chest level.
• Use caution when installing the server in or removing the
server from the rack; it is unstable when not fastened to the
rails.
WARNING: To reduce the risk of personal injury from hot
surfaces, allow the drives and the internal system components to
cool before touching them.
WARNING: To reduce the risk of personal injury, electric
shock, or damage to the equipment, remove the power cord to
remove power from the server. The front panel Power On/Standby
button does not completely shut off system power. Portions of the
power supply and some internal circuitry remain active until AC
power is removed.
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 15
CAUTION: Do not operate the server for long periods with the
access panel open or removed. Operating the server in this manner
results in improper airflow and improper cooling that can lead to thermal
damage.

To replace the component, reverse the removal procedure.
For DIMM configuration information, refer to DIMM installation guidelines (on
page 24
).
24 HP ProLiant ML310 Generation 2 Server Maintenance and Service Guide
DIMM installation guidelines
Observe the following guidelines when installing additional memory:
• DIMMs installed in the server must be Unbuffered DDR DRAM, 2.5 volts,
64 bits wide, and ECC.
• If only a single DIMM is installed, it must be installed in slot 1A.
• All DIMMs installed must be the same speed.
BIOS detects the DIMM population and sets the system as follows:
• Single-channel mode: DIMMs installed in one channel only.
• Dual-channel asymmetric mode: DIMMs installed in both channels but of
unequal capacities per channel.
• Dual-channel interleaved mode: DIMMs installed in both channels with
equal channel capacities.
The following table lists some, but not all, possible configurations. For best
performance, HP recommends dual-channel interleaved mode configurations.
