Startup Self-test Results
The results of the startup self-test that was done when the routing switcher started up the last
time can be displayed using the diagnostics screen in terminal protocol. Enter “D” to display this
screen Refer to Terminal Protocol section for more information. A startup self-test result code will
be displayed as an 8-bit number: ABCDEFGH. Bits that are 1 indicate failures. These failures bits
are interpreted as follows:
In addition, the diagnostics screen shows the last several errors detected by the software and
stored in non-volatile member. Currently, the only error that is detectable is a startup self-test
failure, and this is shown as “StartupTests ABCDEFGH”, where ABCDEFGH have the same
interpretation as described above. If for example the regular RAM byte test failed five different
times during startup, the message “StartupTests 01000000” would be displayed five times.
