Disconnecting cables and removing the side cover Attention The presence of 5 V ac standby power might result in damage to the hardware unless you disconnect the power cord from the electrical outlet before you open the server. 1. Remove any media (diskettes or CDs) from the drives; then, power-off all attached devices and the server. Caution The Power Control button on the front of the server does not turn off the electrical current supplied to the server. The server also might have more than one power cord. To remove all electrical current from the server, ensure that all power cords are disconnected from the power source. 2. Touch the rear of the bare metal frame to dissipate any static electricity from your body. 3. Before disconnecting cables, be sure to note where they attach, so that you can correctly reattach them later. Note If you are in the United Kingdom, you must perform step 5 before step 4. 4. Unplug all power cords (cables) from electrical outlets. 5. If you have a modem or fax machine attached to the server, disconnect the telephone line from the wall outlet and the server. 6. Note the location of the remaining cables and cords. 84 Netfinity Server HMM
