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.
