Octel 200/300 S.4.1PB60019−01
8.1 BOOT ROM DIAGNOSTICS
When the OctelR 200/300 is loaded or reloaded (loss of power, system error, or a command), the CPU
and other system modules execute a Power−on Selftest diagnostic, or Boot ROM diagnostic. The
following describes how to access and interpret the boot ROM errors.
The CPU diagnostic displays progress messages at the default baud rate of 9600. You can use an
alternative baud rate:
When locally connected, proceed as follows:
1. Set the baud rate to any of the valid rates: 300, 600, 1200, 2400, 4800, 9600, 19200 or 38400.
2. Turn ON the power.
3. Immediately following power up, press
Enter
repeatedly to establish the baud rate. If you do not
establish the baud rate at this time the header and diagnostic messages print at 9600 baud.
Wait for the operating system to load and the diagnostic selftest to finish. If the tests were completed
successfully, the Octel 200/300 displays INITIALIZING PORTS...PORT INITIALIZATION
DONE. The word FAILED displays if one of the tests fail. A sample screen is shown below.
4. When the password prompt is displayed, enter the password, and press
Enter
.
5. The operating system @ prompt appears.
When remotely connected, proceed as follows:
Call the Octel 200/300 from a compatible modem-equipped terminal. When you hear the company
greeting, access the modem by entering
# # # 5
, or access the modem through a modem-access
mailbox, if it is used. The message server responds with a high-pitched tone. Connect your modem. The
Octel 200/300 header should appear shortly. Proceed as if directly connected.
The complete diagnostic message shown below is printed. The word FAILED displays if one of the tests
fail.
