Figure 1-12 Bandwidth Utilization for the Catalyst 3548 XL
If all port status LEDs on the Catalyst 3548 XL are green, the switch is using 50% or more
of its total bandwidth capacity. If all 10/100 port status LEDs are green and the lower GBIC
LED is amber, the switch is using between 25% and 50% of its total bandwidth. If all
10/100 port status LEDs are green and if both the GBIC LEDs are amber, the switch is
using less than 25% of its total capacity, and so on.
Rear-Panel Description
Switch rear panels have an AC power connector, an RPS connector, and an RJ-45 console
port (see Figure 1-13, Figure 1-14, and Figure 1-15). These components are described in
this section.
Power Connectors
You can provide power to the switch either by using the internal power supply or by
connecting the Cisco RPS to the switch RPS connector. The internal power supply is an
autoranging unit that supports input voltages between 100 and 240 VAC. If you plan to use
the internal power supply, use the supplied AC power cord to connect the AC power
connector to an AC power outlet.
