Cleaning the Keyboard and Mouse
IMPORTANT:
A keyboard and a mouse use USB interface. Therefore it is not necessary to
power off the server when connecting or disconnecting them.
Disconnect the keyboard from the server while the devices in the system (the server and the
peripheral devices) remain turned on. Wipe the keyboard surface with a dry cloth. Then connect the
keyboard to the server.
The mouse operation depends on the degree of smoothness of the internal ball rotation. To keep the
mouse ball clean, use the mouse in a place with little dust. Follow the steps below to clean the
mouse regularly:
1.
Disconnect the mouse from the USB hub of the keyboard while the server remains
powered on.
2.
Turn the mouse upside down, and rotate the mouse ball
cover counterclockwise to remove it. Take out the ball
from the mouse.
