Preparing the server for hardware maintenance
.
DANGER
Risk of electric shock
Before you begin working inside the server, do the following:
1 Power off and disconnect all peripheral devices that are
connected to the HMS 400 server.
2 Power off the server and disconnect the power cord.
For more information, see “To disconnect the power and
peripheral device cables” on page 98.
.
CAUTION
Risk of electrical damage
•
Wear an antistatic ESD wrist strap when handling cards or
boards, or when working inside the server.
• Place hardware components on an antistatic surface until
you are ready to install them.
• Do not touch the components or gold-edge connectors of
cards or boards.
.
CAUTION
Risk of equipment damage
Place the server on its side to prevent the server from
accidentally falling over. This provides greater stability. If you
attempt to work with the server in its standing position, it may
tip over when you remove or insert components.
If the server is equipped with chassis feet, do one of the
following:
• Remove the feet so that the server lays flat on the working
surface. For more information, see “To remove the chassis
feet” on page 100.
• Place stable material beneath the server to raise the feet
away from the working surface. This allows the server to
lay flat on the working surface.
• Pull the server forward so that the feet hang over the edge
of the working surface.
