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 2-23 and Figure 2-24.)
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 2-25.)
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 2-26.)
