Agent Greeting Card Maintenance and Troubleshooting Guide
The RS-232 port may also be used to monitor the progress of self tests.
Messages indicating the completion of each self test phase, as well as any
detected faults will be printed to this port. Support for boundary scan and
access to the boundary scan interface on the FPGAs is provided.
Status LED
A single red LED is provided on the faceplate to indicate the enabled /
disabled status of the Agent Greeting Card, as well as providing an indication
of the status of the power on self test.
The LED is OFF if:
• the port capacity of the Agent Greeting Card is non-zero.
and
• the card is in the normal mode of operation.
The LED is ON if:
• the port capacity of the Agent Greeting Card is zero.
or
• the card is in maintenance mode.
Reset Switch
A reset switch is provided on the faceplate to allow an operator to manually
reset the card without having to power down. This switch is normally used to
clear a fault condition during setup or during non-traffic periods.
!
CAUTION
Before using the Reset switch ensure that the Agent
Greeting card has been disabled in LD 32 using the DISC
command. Otherwise some of the ports may cause an
OVD error on the Meridian CPU and become disabled
when the card resets. Once the card is active again (the
Hex display has passed T:21 state) reenable the card in
LD 32 using the ENLC command.
