Pressing selected keys on the terminal immediately after the “Force EPROM
download” message is displayed will change the switch start-up process
(Table 1).
During the start-up process the switch will generate four different types of
messages. All messages are preceded by one of the words INFO, PASS, FAIL,
or ERROR. The significance of these words is shown in Table 2.
The possible messages and their meanings are:
INFO: Self tests beginning.
The code loader tests are about to begin.
INFO: RAM test beginning.
The RAM tests are about to begin.
PASS: RAM test, 32768k bytes found.
The RAM test passed, and the indicated amount of memory was found
and will be used in the switch.
ERROR: RAM test 5. Error address = 00345678.
A RAM test failed, at the given address. In the example, it was the fifth
test run. The RAM test repeats until it passes, so a number of messages
like this may appear. This fault means that the memory system is faulty.
If the fault continues, contact your Authorised Allied Telesis distributor
or reseller immediately.
INFO: Self tests complete.
The start-up tests have finished.
INFO: Downloading switch software.
The process of downloading the switch software and vector table from
ROM is about to begin.
