If applicable, loosen the captive screws and remove the slot cover.

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.

The power off sequence for the interconnected 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+/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+/MPMx card

removal.

—

Port usage is re-calculated and the Port Gauges and Video/Voice

Port Configuration dialog box are updated.

When the blue HS LEDs on the 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+/MPMx card.

Warning!
Once the removal sequence is initiated the process cannot be terminated and
the HS LED flashes.
