Replacing a Faulty MPM/MPM+ Card
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.
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.
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/
MPM+ card.
Warning!
Once the removal sequence is initiated the process cannot be terminated and
the HS LED flashes.
