Chapter 1 Safety Precautions for Maintenance 1-3
1.2 Server Precautions
When maintaining the server, observe the following precautions for your protection.
■
Follow all cautions, warnings, and instructions marked on the server.
Caution –
Do not insert any object in an opening of the server. If any object comes
into contact with a high-voltage part or short-circuits a component, fire or electric
shock might result.
■
Refer servicing of the server to the service engineer.
1.2.1 Electrical Safety Precautions
■
Ensure that the voltage and frequency of the AC power source to be used matches
the electrical rating labels on the server.
■
Wear antistatic wrist straps when handling hard disk drives, motherboard units,
or other printed circuit boards.
■
Use grounded power outlets as described in the SPARC Enterprise M3000 Server
Installation Guide .
Caution – Do not make mechanical or electrical modifications. We are not
responsible for regulatory compliance of modified servers.
1.2.2 Equipment Rack Safety Precautions
■
The equipment racks must be anchored to the floor, ceiling, or to adjacent frames.
■
Some equipment racks are supplied with a stabilizer feature, which supports the
weight of the server when it is extended on its slide rails. This prevents the
equipment from toppling over during installation or maintenance.
■
In the following cases, a safety evaluation must be conducted by the service
engineer prior to installation or maintenance work.
■
When no stabilizers are attached and the equipment rack is not anchored to the
floor, ensure safety by confirming that the server does not fall over when it is
pulled out from the slide rails.
