Nortel Proprietary
9.3 Factory Test Features
Factory test features include the HEX Display, Status LED and Reset Switch.
HEX Display
The Nortel Remote Agent Observe base card includes a HEX LED display on the
faceplate to provide status information during maintenance operations. During
power-up and diagnostic tests, this display provides a visual progress indication,
and information on the first failure detected. The HEX LED display codes are
indicated in Table 13.

Table 13 HEX Display codes during boot-up
If the internal RAM test, ALU test, address mode test, boot ROM test, timer test, or
external RAM test fails, the pack goes into a maintenance loop as no further
processing is possible.
If a test fails, "F:XX" shows on the hex display for three seconds after the "T:13"
message, with the number represented by "XX" indicating the test that failed. For
example, if the 8051 co-processor test failed, "F:05" shows. If more than one test
fails, the message indicates the first failure.
