If all LEDs on Catalyst 2950-12, 2950-24, 2950C-24, 2950SX-24, and 2950T-24
switches are green (no amber showing), the switch is using 50 percent or more of
the total bandwidth. If the far-right LED is off, the switch is using more than 25
but less than 50 percent of the total bandwidth, and so on. If only the far-left LED
is green, the switch isp using less than 0.0488 percent of the total bandwidth. (See
Figure 1-16.)
If all LEDs on Catalyst 2950G-12-EI switches are green (no amber showing), the
switch is using 50 percent or more of the total bandwidth. If the LED for GBIC
module slot 2 is off, the switch is using more than 25 but less than 50 percent of
the total bandwidth. If LEDs for both GBIC module slots are off, the switch is
using less than 25 percent of the total bandwidth, and so on. (See
If all LEDs on Catalyst 2950G-24-EI and 2950G-24-EI-DC switches are green
(no amber showing), the switch is using 50 percent or more of the total bandwidth.
If the LED for GBIC module slot 2 is off, the switch is using more than 25 but less
than 50 percent of the total bandwidth. If LEDs for both GBIC module slots are
off, the switch is using less than 25 percent of the total bandwidth, and so on. (See
Figure 1-18.)
