Activity N1: Testing
LEDs
All front panel LEDs light for a few seconds, then all but the Power
LED turn off, confirming that all LEDs are operational.
Activity N2: Testing
the Hardware
During the power-up sequence, the Remote Annex 4000 runs a series
of self-test diagnostics. These diagnostics test internal hardware
functions. The Power LED lights for a few seconds, then the 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 4000 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 4000 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 4000 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 4000 is ready.
