Fibre Channel Gateway LEDs
Fibre Channel Gateway Card Status LEDs
Each Fibre Channel gateway card includes two LEDs (one green and one yellow) as shown in
Figure 5-2
.
These indicators describe the Fibre Channel card status. The OK label is for the green LED, and
the ! label is for the yellow LED.
Table 5-4
describes the Fibre Channel gateway card LED indicators.
Fibre Channel Gateway Port Status LEDs
Two LEDs are provided for each Fibre Channel port on each Fibre Channel gateway card. The LEDs
indicate status/activity and speed (see
Figure 5-2
).
Table 5-5
describes the Fibre Channel port status
LED indicators. The Link status indicator is a green LED, and the Fault indicator is a yellow LED.
