Remote Annex 6300 Hardware Installation Guide

Chapter 4 Troubleshooting Procedures

4-6

Activity N2: Testing

the Hardware

During the power-up sequence, the Remote Annex 6300 runs a series

of self-test diagnostics. These diagnostics test internal hardware

functions. If a test fails, the ATTN and STAT LEDs flash and an error

message is displayed on the console port. The Ethernet LED (Link

LED) lights for a few seconds, then the TRAF LED flashes during the

power-up self-tests. After the self-tests complete, only the STAT and

Ethernet Link LED remain on.

Normal Mode Error Sequence

Table 4-3 shows the state of the LEDs when an error occurs at various

stages of the start-up process. If the Remote Annex 6300 fails during

the hardware-test state (N2), the error condition is hardware failure

NE2. A description of possible causes and solutions for each error

condition is in the following paragraphs.
