Fast Ethernet PRI Module LEDs
All network modules have an enable (EN) LED. This LED indicates that the module has
passed its self-tests and is available to the router.
All Fast Ethernet PRI modules have four LEDS for the Fast Ethernet port, and four
additional LEDs for each PRI port. Figure 5-14 shows LEDs for the 1-port Fast Ethernet
2-port channelized E1/ISDN PRI balanced (120-ohm) network module as an example.
