Rear-Panel Description
Other than the Catalyst 2950G-24-EI-DC switch and the Catalyst 2950 LRE switches, the rear panel of
a Catalyst 2950 switch has an AC power connector, an RPS connector, and an RJ-45 console port. (See
Figure 1-25 and Figure 1-26.)
The rear panel of the Catalyst 2950G-24-EI-DC switch has a DC power connector (also referred to as
the terminal block header), a DC ground lug, an RPS connector, and an RJ-45 console port. (See
Figure 1-27.)
The rear panel of the Catalyst 2950ST-8 LRE, 2950ST-24 LRE, and 2950ST-24 LRE 997 switches has
only an RPS connector. (See Figure 1-28.)
