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.
