Verify either hardware or software switch-over
To verify either hardware or software switch-over.
1.
Connect a NULL modem cable (GE Energy part number 977-0529) to the RS-232
connector on the front panel of the D20MX designated as CCU B, which was originally
the Standby unit.
2.
Attach the other end of the cable to the serial communications port of the PC or
terminal.
3.
Login to WESMAINT II+ through the emulator you are using.
Result: The WESMAINT Main Menu appears.
4.
If you can login to WESMAINT II+, this indicates that CCU B is the Active CCU.
Results: Fail over has occurred.
NOTE
If the previously Active A CCU powers-up after a fail-over from CCU A to CCU B, then
STNDBY appears at top left when you login to WESMAINT II+ on CCU B. This can take
up to a minute to occur.
NOTE
If you cannot login to WESMAINT II+ on a CCU, then the unit is most likely powered down.
Verify that the RDY LED is flashing and verify that the serial cable is connected correctly.
