BUILDING NETWORK ADAPTER BNA-1C/2CS/2DN
Shows the actual LAN traffic using 4 LEDs.
Col | Collision indicator |
|
| (Red) | |
| If this LED is on, then two or more | ||||
| devices on the network are | ||||
| transmitting at the same time. This is | ||||
| not a fault, but a normal occurrence | ||||
| on an Ethernet network. However, | ||||
| when the Collision LED remains on | ||||
| for all transmission attempts, it may | ||||
| indicate an abnormal condition such | ||||
| as an open | ||||
Rx | Receive indicator |
| (Green) | ||
| on means that data is received by the | ||||
| BNA over the Ethernet. |
|
| ||
Tx | Transmit indicator |
| (Green) | ||
| If this LED is lit up, then the BNA | ||||
| device sends data to the Ethernet. | ||||
| When data is transmitted, the Rx | ||||
| indication | LED | is | lit | up |
| simultaneously. |

Lnk | Link indicator |
|
| (Green) | |
| shall always be on when the BNA is | ||||
| connected via the RJ45 connector to | ||||
| the Ethernet. If this LED is off under | ||||
| this circumstance, then it will not be | ||||
| possible to send or receive any data. | ||||
| If an AUI transceiver is used to hook | ||||
| up the BNA to the network, then this | ||||
| LED will be off in most cases because | ||||
