Troubleshooting
A.1.2 Check Self-Test (Automatically Performed)
During a system boot, the ATM adapter automatically performs a self-test of
the hardware, running a low-level diagnostic which checks memory
read/write capability. Upon completion of the self-test, a message is printed
to the console of the workstation indicating whether or not the hardware
failed.
If the self-test is successful, proceed to the instructions regarding the firmware
download as described in the next subsection.
If the self-test fails, reseat the board by performing the following steps to
ensure that failure was not due to improper insertion of the board:
1. Halt the system, being sure to follow the procedures outlined in
Chapter 2 of the User’s Manual for the adapter.
2. Open the computer as shown in Chapter 2 of the User’s Manual
for the adapter, and reseat the board.
3. Reboot the system.
If the board still fails after a reseat, then it should be returned for repair. Call
Cabletron Systems’ Technical Support for further assistance.
A.1.3 Firmware Download (Automatically Performed)
Before operating as an ATM interface, the firmware is automatically down-
loaded from the system RAM to the onboard i960 processor during host sys-
tem boot. A message similar to: “XXX-200 initializing...” is displayed on the
console, indicating that the board is being initialized. When the initialization
is complete, success is indicated with the message “done” and failure is indi-
cated with the message “failed”.
If the download is successful, check to see if the hardware has been detected
by the driver as described in the next subsection.
If the firmware failed to download, then there is most likely a hardware prob-
lem. Call Cabletron Systems’ Technical Support for further assistance.
