Applying Chassis Power
Checking Power Supply
and Module Status
Check the LED indicators and alphanumeric display to determine if
the power supply and module are operating properly.
The alphanumeric display should cycle through the following states:
“TEST - PASS - OK - REV x.x,” where “x.x” is the module’s firmware
revision. The display then alternates between “OK” and the module’s
default BOOTP address.
If the alphanumeric display and LED indicators do not produce the
expected states refer to Appendix A for help in troubleshooting your
module.
