Figure 1-21 Bandwidth Utilization on Catalyst 2950-24, 2950C-24, 2950SX-24, and 2950T-24 Switches
If all LEDs on a Catalyst 2950G-12-EI switch 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 1-22.)
Figure 1-22 Bandwidth Utilization on Catalyst 2950G-12-EI Switches
If all LEDs on a Catalyst 2950G-24-EI or 2950G-24-EI-DC switch 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 1-23.)
Figure 1-23 Bandwidth Utilization on Catalyst 2950G-24-EI and 2950G-24-EI-DC Switches
If all LEDs on a Catalyst 2950G-48-EI, 2950SX-48-SI, or 2950T-48-SI switch are green, 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 1-24.)
