Cajun A500 Diagnostics
The first step in any diagnostic procedure involving the A500 is to identify the
OC-3 ports on the A500 that have S8700 Multi-Connect port networks attached.
■ Be aware that customers may use other ports on the A500 for applications
unrelated to S8700 Multi-Connect (for example, LAN traffic or multimedia
applications).
■ These other applications may manifest themselves in the output of the
troubleshooting commands you run on the A500. S8700 Multi-Connect
port networks must be identified by their A500 port numbers.
NOTE:
The following examples show S8700 Multi-Connect port networks
connected to A500 ports A1.1 and A1.2.
Diagnostics
Has the A500 been installed and configured correctly?
■ Is the A500 powered up?
■ If you are administering the A500 through a locally attached console, is
there a local console terminal connected to the console port on the A500
switch processor board with the correctly pinned RS232 serial cable?
■ If you are administering the A500 through Telnet over the Ethernet, is there
an 10BaseT Ethernet drop plugged into the Ethernet port on the A500
switch processor board? (Note that a few A500 commands are only
permitted over the local console terminal.)
■ Has the A500 been booted using either the recessed reset button or by
turning the power off, then on again?
■ Did the A500 go through a normal power-up sequence, including testing
every LED?
■ Are any A500 amber fault LEDs lit?
■ Are the remaining A500 LEDs in a normal state (Table 4-5 on page 4-29)?
■ Can you log into the A500 console using the diagnostic account root from
the local console terminal or through Telnet? (See Figure 4-7 on page
4-32.)
