Chapter 1 Maintenance
Cleaning the server
Wipe the external surfaces of the server with a dry soft cloth. Follow the steps below if stains remain on the
surfaces.
Important Do not use thinner and benzene, and other volatile solvents to clean the
server.
The power outlet, cables, connectors on the rear panel of the server, and
the inside of the server must be kept dry.
1. Confirm that the power is OFF (POWER LED is OFF).
2. Unplug the power cord of the server from a power outlet.
3. Wipe off dust from the power cord plug with a dry cloth.
4. Soak a soft cloth in neutral detergent that is diluted with cold or lukewarm water, and squeeze it firmly.
