Front Panel Indicators; Table 4-1 Bni Front Panel Status Indicators - Cisco BPX-BXM-155-8DX Installation And Configuration Manual

Broadband Network Interface Cards (BNI-T3 and BNI-E3)
•
When a trunk has been assigned to a BNI card but is not yet activated (upped), it is put in a loopback
mode and a diagnostic test is continuously performed. This loopback is disruptive so it cannot be
performed on a card that has an active trunk. This diagnostic test checks the data path through the BNI
out to the BCC, through the switch matrix, and back to the BNI.
Active trunks are constantly checked by the Communications Fail test routine which is part of system
software.

Front Panel Indicators

The lower section of the BNI front panel (see Figure 4-3) has a three-section, multicolored LED to
indicate the card status. The card status LED is color-coded as indicated in Table 4-1.
At the upper portion of the front panel, there is a three-section multicolored LED to indicate the status
of the three ports on the BNI. Types of failures are indicated by various combinations of the card status
indicators as indicated in Table 4-2.
