Chapter 2- Component Replacement

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 

—

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.
