Cleaning the Interior
CAUTION
Only a qualified service representative can only install or remove the
components described in this subsection. To avoid personal injury or electrical
shock, contact your service representative when you need to install/remove the
internal components.
One of the most important items of a good maintenance program is a regular and thorough cleaning of the inside of the
server, especially around the base board.
Dust buildup inside the server can lead to several problems. As dust acts as a thermal insulator, a buildup can prevent
proper system cooling. Excessive heat will shorten the life of the server components. The dust may also contain
conductive or corrosive materials that can cause short circuits or corrosion of the electrical contacts.
The frequency at which you should clean the inside of the server depends on the environment in which it is located. For
most office environments, every 12 months is probably sufficient. For more severe environments, clean the inside every
6 months.
Cleaning the interior of the server implies powering off the server and removing the left side cover. You will need a
small vacuum cleaner (with a plastic tipped nozzle and electrostatic protection), computer grade canned air, and a small
brush.
Follow the procedure below to clean the inside of the server.
WARNING
Unplug all power cords.
Unplug all power cords before performing any maintenance. Voltage is present
inside the server and display unit even after the power is turned off. All voltage
is removed only when the power cord is unplugged.
IMPORTANT: Do not use a brush made of chemical fabric, or cleaning materials that can
generate electrostatic electricity.
1. Turn off the server and unplug all power cables.
2. Remove the left side cover. (See Chapter 9.)
3. Remove the dust accumulated on the air inlet of the front and the rear fan.
4. Use a small brush to loosen any dust and debris on the base board.
5. Use computer grade canned air to blow dust off components on the base board.
6. Use a small vacuum cleaner with a plastic tip to vacuum out the dust and debris from the inside of the server.
7. Reinstall the left side cover. (See Chapter 9.)
8. Reconnect all the power cables and power on the server.
