Activity T1: Testing
LEDs All front panel LEDs light for a few seconds, then all but the Power
LED turn off. This sequence confirms that all LEDs are operational.
At this point, the Remote Annex 2000 is in normal mode; pressing the
button readies it for the next activity.
Activity T2: Testing
the Hardware During power-up, the Remote Annex 2000 runs self-tests that execute
CPU diagnostics, ROM and E2 ROM checksums, internal serial port
and LAN loopbacks, and RAM tests. The Unit and Active LEDs flash
during the power-up tests. After completing the power-up self-tests,
only the Unit and Power LEDs remain on.
Activity T3: Testing
the Network The Remote Annex 2000 sends a short packet addressed to itself
through the transceiver to test the transceiver and its cable. The Net
LED flashes during the test. After completing the test, the Net LED
remains on.
Activity T4: At the
Monitor Prompt When the Power, Unit, and Net LEDs are on, the console terminal
displays the ROM Monitor prompt. Enter the boot command at the
prompt. If you did not enter a file name with the command, a prompt
asks you for one.
Activity T5: Looking
for the Boot File The Load LED flashes while the Remote Annex 2000 waits for a
response to its load request from a load server host.
Activity T6: Loading
Code with the boot
Command The Load LED lights when the Remote Annex 2000 tries to load from
a load server host. The Remote Annex 2000 loads its operational code
when a host responds. The console terminal displays messages
describing the boot request and the boot process.
Activity T7: Running
Operational Code After the Remote Annex 2000 loads the proper image, the Load LED
turns off. The Remote Annex 2000 is ready.
