blue HS LED on the card and the Control Unit start to flash.
3 The power off sequence for the interconnected MPM+ and RTM
ISDN cards are initiated as follows:
All participant connections on the card are disconnected.
A fault is generated on the system.
For each disconnected participant, a participant disconnection
event is written to the CDR with the disconnection cause
Disconnected by Operator.
New participant connections are blocked when the card is
removed.
If an RTM ISDN card is connected to the MPM+ card it is also
powered off and all ISDN and PSTN participants are
disconnected.
When an RTM ISDN card is removed, its resources are deducted
from the Resource Report.
A Log File entry is written indicating MPM+ card removal.
Port usage is re-calculated and the Port Gauges and Video/Voice
Port Configuration dialog box are updated.
4 When the blue HS LEDs on the MPM+, RTM ISDN and Control Unit
stop flashing and remain lit, unscrew the captive screws and move
the ejector levers to their fully open position and remove the MPM+
card.
Warning!
Once the removal sequence is initiated the process cannot be terminated and
the HS LED flashes.
