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 1-9 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 1-9 shows the Catalyst 3550-12T switch as an example. All the Catalyst switches have similar
components.
