Interpreting the LEDs
Interpreting
the LEDs
The LEDs give information about the status of a particular unit or
function. Each 2072 BNC Module has a set of 10 link/partition
LEDs which display port status.
In addition, there are two LEDs which represent AUI Port Link and
Partition status, and two LEDs used to indicate on which Ethernet
segment the repeater card is configured.
LEDs can be categorized into the following four groups:
❏ AUI port partition, link/receive
❏ Port-by-port partition
❏ Port-by-port link/receive
❏ Segment configuration
Table 2 lists and defines the module LEDs.
