Electrical safety Electrical safety 10 CAUTION: Electrical current from power, telephone, and communication cables can be hazardous. To avoid personal injury or equipment damage, disconnect the attached power cords, telecommunications systems, networks, and modems before you open the server covers, unless instructed otherwise in the installation and configuration procedures. For your safety, always do the following before removing the cover: 1. Turn off the server and any attached devices, such as printers, monitors, and external drives.

When reassembling your server, you must reconnect the telephone line after you plug in the power cords. 2. Unplug all the power cords from electrical outlets. 3. Disconnect all communication cables from external receptacles. 4. Disconnect all cables and power cords from the back of the server. Note: Reconnect the cables or power cords only after you reassemble the server and put the cover back on. 70 Netfinity 3000 User's Handbook
