Diagnostics
The switch software includes a set of diagnostic programs. These programs
perform basic level checks of all system components. They do not run in
conjunction with the normal operating code, and require that the system be
totally dedicated to their use. A detailed knowledge of the way the switch
hardware functions is necessary if diagnostics are to be used effectively.
Note The switch will not perform switching operations if diagnostics are
running.
Warning This section is not intended as a guide to the diagnostics software.
Diagnostics are designed to be run by service personnel only. For more
information, contact your authorised distributor or reseller.
How to enable diagnostics mode:
1. Connect a terminal to the RS-232 Terminal Port (ASYN0).
Use a terminal cable to connect a terminal to the RS-232 Port (ASYN0) on
the switch. For more information on terminal cables see “Useful Cables” on
page 19.
Set the terminal communication parameters to:
• Baud rate: 9600
• Data bits: 8
•Parity: None
•Stop bits: 1
• Flow control: Hardware
2. Restart the switch.
To restart the switch use a small diameter pin to operate the recessed Reset
button on the switch’s front panel, or use the terminal to log in and enter
the command:
