Replacing a Faulty MPM/MPM+/MPMx Card
Removing the MPM/MPM+/MPMx Card from the MCU
All MPM/MPM+/MPMx cards can be installed or removed while the RMX 2000 is powered
on and operating.
Prior to removing an MPM/MPM+/MPMx card the captive screws must be unscrewed and
the ejector levers must be opened to initiate a "power down" on the card.

If applicable, loosen the captive screws and remove the slot cover.
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.
The power off sequence for the interconnected MPM/MPM+/MPMx 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+/MPMx 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
list.
— A Log File entry is written indicating MPM/MPM+/MPMx card removal.
— Port usage is re-calculated and the Port Gauges and Video/Voice Port Configuration
dialog boxes are updated.
When the blue HS LEDs on the MPM/MPM+/MPMx, 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.
Carefully slide the MPM/MPM+/MPMx card out through the front panel.
