Normal LED Indications (Front)
Light |
Status |
Description & Suggested Action (Likely Failures in Bold) |
| SYSTEM PWR |
Green (Solid) |
Power is being supplied to the Router. |
| SYSTEM OK |
Green (Solid) |
The Router is connected to your local Ethernet network through the ETHERNET 10 Base-T
Port. |

Blinking means that there is network traffic on your local Ethernet network. |
Normal LED Indications (Back)
Light |
Status |
Description & Suggested Action (Likely Failures in Bold) |
| LNK |
Green (Solid) |
When the LED is on, the Router is connected to your local Ethernet network through the ETHERNET 10 Base-T
Port. |
| CARRIER |
Green (Solid) |
On means that the cable is correctly connected and the Router can communicate across the WAN. |
| ALARM |
LIT |
If CARRIER is green and ALARM is lit, you are getting either framed
or unframed all ones, more than likely. This is either a problem with
the carrier not cross connecting your circuit to something useful or
equally likely, a problem with the TX pair going between you and the
SmartJack. // Checking the SmartJack for a local alarm would tell you the
difference. |
| LOOPBACK |
LIT |
Your circuit is in loopback. // You can typically clear this
loopback by powercycling the equipment or hitting the loopback button on
the WIC with an ink pen. (If you just reported an issue, your Carrier may
be testing your circuit and you don't want to do this.) |
| FLASH PC CARD |
Green (Solid) |
On means that the Flash PC card is correctly installed. |
