Front-Panel Description
For more information about GBIC LEDs, refer to your GBIC module
documentation.
Figure 2-18 to Figure 2-22 show the bandwidth utilization percentages displayed
by the right-most LEDs.
Note The Catalyst 2950 LRE switch LEDs do not give utilization status.
If all LEDs on a Catalyst 2950-12, 2950-24, 2950C-24, 2950SX-24, or 2950T-24
switch 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 is using less than 0.0488 percent of the total bandwidth. (See
Figure 2-18 and Figure 2-19.)
