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.

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+/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 Report.

— 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 box are updated.

4 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.

Warning!

Once the removal sequence is initiated the process cannot be terminated and

the HS LED flashes.
