The Cisco 1600 LEDs

BRI 0
SYSTEM LAN
WIC
B1
OK PWR
ACT COL
CD
B2 ACT


You should understand what each indicator means, as explained in the following list:
System PWR The green System power LED illuminates to show that the system is on and
receiving power.
System OK The green System OK LED blinks during the boot cycle. After the boot cycle is
complete, this LED is steady.
BRI0 B1 and BRI0 B2 These LEDs display active connections on the BRI0 B1 and B2 channels,
respectively. BRI 0 is the first ISDN BRI interface on the router.
WIC CD This LED denotes a connection on the WAN Interface Card. This indication can be
helpful when troubleshooting DSU/CSU issues.
WIC ACT The WAN Interface Card activity LED can be used to indicate circuit use,
although it is helpful to use the command-line interface to see the direction and characteristics
of the traffic itself.
LAN ACT The LAN activity LED is similar to the WIC activity LED, but it represents traffic
on the Ethernet interface.
LAN COL The LAN collision LED indicates a collision on the Ethernet segment. It is yellow,
unlike the other LEDs, which are all green.
