Removing the MPM/MPM+ Card from the MCU

All MPM/MPM+ cards can be installed or removed while the RMX 2000
is powered on and operating.
Prior to removing an MPM/MPM+ card the captive screws must be
unscrewed and the ejector levers must be opened to initiate a "power
down" on the card.
1
If applicable, loosen the captive screws and remove the slot cover.
2
Power down the card by partially opening the ejector levers until the
blue HS LED on the card and the Control Unit start to flash.
Warning!
Once the removal sequence is initiated the process cannot be terminated and
the HS LED flashes.
3
The power off sequence for the interconnected MPM/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/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/MPM+ card removal.
— Port usage is re-calculated and the Port Gauges and Video/Voice
Port Configuration dialog box are updated.

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/
MPM+ card.
