shock, fire, or damage to the equipment,
do not plug telecommunications or
telephone connectors into the network
interface card (NIC) (labeled as an Ethernet
connector).
2 Reconnect the modem/telephone cable and all
other cables (such as the keyboard, mouse, and
monitor) and external devices.

lift it off the unit.

the chassis.
Replacing the Side Panel
