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.
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+/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.
