Chapter 1- Hardware Description
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.
1If applicable, loosen the captive screws and remove the slot cover.
2Power 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.
3The 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
4When 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.
