Rear-Panel Description
Other than the Catalyst 3550-24-DC switch, the switch rear panels have an AC
power connector, an RPS connector, and an RJ-45 console port, which are shown
in Figure 2-9 and described in this section.
The rear panel of the 3550-24-DC switch has a DC power connector (also referred
to as the terminal block header), an RJ-45 console port, and a ground lug. The
switch is shipped with a terminal block plug in the DC power connector.
Note Figure 2-9 shows the Catalyst 3550-12T switch as an example. All the Catalyst
switches have similar components.
