Chapter 4 Troubleshooting Procedures

Activity N2: Testing

the Hardware

During the power-up sequence, the Remote Annex 2000 runs a series

of self-test diagnostics. These tests verify internal hardware functions.

The Power LED lights for a few seconds, then Unit and Active LEDs

flash during the power-up self-tests. After the self-tests complete,

only the Unit and Power LEDs remain on.

Activity N3: Testing

the Network

The Remote Annex 2000 sends a short packet addressed to itself

through the transceiver to test the transceiver and its cable. After

passing this test, the Net LED flashes and remains on.

Activity N4: Looking

for the Boot File

The Load LED flashes while the Remote Annex 2000 waits for a load

server host to respond to its load request.

Activity N5:

Loading the Code

The Load LED lights while the Remote Annex 2000 loads its

operational code from a load server host.

If a port is set up for syslogging, the associated LED will ﬂash

when data is output on the port, thus interfering with the

normal LED sequence.

Activity N6:

Running the

Operational Code

The Load LED turns off when the proper image is loaded. The

operational code has control, and the Remote Annex 2000 is ready.
