Electrostatic Discharge Information
An electrostatic discharge (ESD) 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 workstations with approved static-dissipating material. Use a wrist strap connected
to the work surface, and properly grounded (earthed) tools and equipment.
Keep work area free of nonconductive materials, such as ordinary plastic assembly aids
•
and foam packing.
Make sure that you are always properly grounded (earthed) when touching a
•
static-sensitive component or assembly.
Avoid touching pins, leads, or circuitry.
•
Always place drives with the Printed Circuit Board (PCB) assembly-side down.
•
Use conductive field service tools.

Removal and Replacement Procedures
HP ProLiant ML350 Generation 3 Server Maintenance and Service Guide 2-3
Removal and Replacement Procedures
Preparation Procedures
WARNING: Only authorized technicians trained by HP should attempt to repair this
equipment. Because of the complexity of the individual boards and subassemblies, no
one should attempt to make repairs at the component level or to make modifications to
any printed wiring board. Improper repairs can create a safety hazard.
CAUTION: Electrostatic discharge (ESD) can damage electronic components. Be sure that
you are properly grounded (earthed) before beginning any installation procedure. Refer to
“Electrostatic Discharge Information” earlier in this chapter for more information.
Before removing any serviceable parts, determine whether the part is hot-pluggable or
non-hot-pluggable.
Non-Hot-Pluggable Device
If the device is non-hot-pluggable, the server must be powered down. Non-hot-pluggable
devices in the server include the processor, all boards, memory modules, fans, PCI option
cards and drive cages.
Powering Down the Server
The server does not completely power down when the front panel power button is pressed.
The button toggles between On and Standby. The standby position removes power from most
electronics and the drives, but some internal circuitry remains active. To completely remove
all power from the system, disconnect all power cords from the server.
WARNING: To reduce the risk of injury from electric shock, disconnect all power cords
to completely remove power from the system.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal
system components to cool before touching them.
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.
CAUTION: The server must always be operated with system unit covers on. Proper cooling is
not achieved when the system unit covers are removed.
2-4 HP ProLiant ML350 Generation 3 Server Maintenance and Service Guide
To power down the server:
1. Press the power button to toggle to Standby. This places the server in standby mode,
disabling the main power supply output and providing auxiliary power to the server.
Standby does not completely disable or remove power from the system.
2. Be sure that the system LED closest to the right on the front panel is amber and that the
fan noise has stopped.
3. Disconnect the AC power cord from the AC outlet, and then from the server.
4. Disconnect all external peripheral devices from the server.
Rack Stability Warning
For stability and safety, properly positioning the server is critical.
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 connected to the rack if it is a single-rack installation.
• The racks are coupled together in multiple-rack installations.
Removal and Replacement Procedures
• Only one component is extended at a time. A rack may become unstable if more
than one component is extended for any reason.
