Installation safety recommendations
To avoid bodily injury or damage to the server, read the following information carefully before you
operate the server.
General operating safety
To avoid bodily injury or damage to the server, follow these guidelines when you operate the server:
•
Only H3C authorized or professional server engineers are allowed to install, service, repair,
operate, or upgrade the server.
•
Make sure all cables are correctly connected before you power on the server.
•
Place the server on a clean, stable table or floor for servicing.
•
To avoid being burnt, allow the server and its internal modules to cool before touching them.
Electrical safety
WARNING!
If you put the server in standby mode (system LED in amber) with the power on/standby button on
the front panel, the power supplies continue to supply power to some circuits in the server. To
remove all power for servicing safety, you must first press the button until the system enters standby
mode, and then remove all power cords from the server.
To avoid bodily injury or damage to the server, follow these guidelines:
•
Always use the power cords that came with the server.
•
Do not use the power cords that came with the server for any other devices.
•
Power off the server when installing or removing any components that are not hot swappable.
Rack mounting recommendations
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 blanking panels to fill
empty rack units.
