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
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.
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.
5
Carefully slide the MPM/MPM+/MPMx card out through the front panel.
Warning!
Once the removal sequence is initiated the process cannot be terminated and the
HS
LED flashes.
