You can also run remote diagnostic tests (by entering remote
diagnostics mode), without traveling to a customer site. By
initiating the tests along with your customer at the customer site, the
test program can reboot the customerÕs system and send data back
through an external modem to a PC at your site, where you can
quickly analyze the data.
Refer to Chapter 3, ÒUsing the Diagnostic Menus,Ó in the
Concorde¥4500 AdministratorÕs Guide, for instructions on running any
of the diagnostic tests, including information on how to enter the
remote diagnostics mode mentioned above.
The power-on self-tests check the hardware and verify the presence
of system boards, cameras, and the wired keypad.
If the system does not power on, if you see no video, or if
you hear no audio, refer to ÒBasic Troubleshooting
ProceduresÓ on page 4-6.
When a test cycle for a board completes, a
message appears next to the board on the screen listing. If a board
fails a test, the remaining tests in the cycle for that board are then
abandoned, and the diagnostics continue with the next board test
cycle in an attempt to power on the system. After all of the boards
have been tested, if any of the boards failed, a message appears
asking you to press any key to continue system startup.
In addition, if a test or tests fail, the red LED on the failed board is lit
instead of the green LED.
When you run the power-on self test you can see the slot
F.Y.I.
number for each board listed next to the board name.
