Installing an MPM+/MPMx Card on the RMX 4000
1If applicable, loosen the captive screws and remove the slot cover.
2On the card to be installed, move the ejector levers to their full open
position.
3Insert the card into the slot until the ejector levers touch the front
edge of the card cage.
4Push the ejector levers to their closed position and tighten the captive
screws on each side of the card, securing the MPM+/MPMx card to
the RMX.
The blue HS LEDs on the MPM+/MPMx card and the Control Unit
start flashing and the power on cycle for the card is initiated:
—The card’s resources are added to the system resources list
—The number of available ports on the RMX is increased to the
current CFS license level
—Port usage is re-calculated and the Port Gauges and Video/Voice
Port Configuration are updated
When the power on cycle of the MPM+/MPMx card is completed,
the blue HS LEDs will turn OFF. The green RDY LED on the MPM+/
MPMx card switches on and remains lit.
Replacing the RTM ISDN Card
1Ensure that the power switch/circuit switch on the RMX 4000 is
turned OFF (O).
2Remove the cables connected to the card.
3Unscrew the captive screws that fasten the card to the MCU.
4Remove the RTM ISDN card. Use the metal ejector levers to pull the
RTM ISDN card out of its slot in the backplane.
5Carefully slide the RTM ISDN card out through the front panel.
On the RMX 4000 when upgrading from MPM/MPM+ to MPMx on the RTM-IP
4000 all connections require Ferrite cables.
