Battery Safety; Safety Precautions; Esd Prevention; Preventing Electrostatic Discharge - H3C UniServer R3950 G6 Manual

Battery safety

The server's system board contains a system battery, which is designed with a lifespan of 3 to 5
years.
If the server no longer automatically displays the correct date and time, you might need to replace
the battery. When you replace the battery, follow these safety guidelines:
•
Do not attempt to recharge the battery.
•
Do not expose the battery to a temperature higher than 60°C (140°F).
•
Do not disassemble, crush, puncture, short external contacts, or dispose of the battery in fire or
water.
•
Dispose of the battery at a designated facility. Do not throw the battery away together with other
wastes.

Safety precautions

NOTE:
Power instability or outage might cause data loss, service disruption, or damage to the server in the
worst case. To protect the server from unstable power or power outage, use uninterrupted power
supplies (UPSs) to provide power for the server.
To avoid bodily injury or damage to the equipment, follow these guidelines when you rack mount a
server:
•
Mount the server in a standard 19-inch rack.
•
Make sure the leveling jacks are extended to the floor and the full weight of the rack rests on the
leveling jacks.
•
Couple the racks together in multi-rack installations.
•
Load the rack from the bottom to the top, with the heaviest hardware unit at the bottom of the
rack.
•
Get help to lift and stabilize the server during installation or removal, especially when the server
is not fastened to the rails. As a best practice, a minimum of two people are required to safely
load or unload a rack. A third person might be required to help align the server if the server is
installed higher than check level.
•
For rack stability, make sure only one unit is extended at a time. A rack might get unstable if
more than one server unit is extended.
•
Make sure the rack is stable when you operate a server in the rack.
•
To maintain correct airflow and avoid thermal damage to the server, use blank panels to fill
empty rack units.

ESD prevention

Preventing electrostatic discharge

Electrostatic charges that build up on people and tools might damage or shorten the lifespan of the
system board and electrostatic-sensitive components.
To prevent electrostatic damage, follow these guidelines:
•
Transport or store the server with the components in antistatic bags.
