displayed changes the router start-up process as described in the following
table.
During the start-up process the router generates four different types of
messages. All messages are preceded by one of the words INFO, PASS, FAIL,
or ERROR. The meaning of these words in the context of the messages is
shown in the following table.
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, 65536k bytes found.
The RAM test passed, and the indicated amount of memory was found
and will be used in the router.
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 distributor or reseller immediately.
INFO: BBR tests beginning.
The BBR tests are about to begin.
PASS: BBR test. Battery OK.
The BBR battery test passed.
