Installing an MPM+/MPMx Card on the RMX 4000
1 If applicable, loosen the captive screws and remove the slot cover.
2 On the card to be installed, move the ejector levers to their full open
position.
3 Insert the card into the slot until the ejector levers touch the front
edge of the card cage.
4 Push 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
1 Ensure that the power switch/circuit switch on the RMX 4000 is
turned OFF (O).
2 Remove the cables connected to the card.
3 Unscrew the captive screws that fasten the card to the MCU.
4 Remove the RTM ISDN card. Use the metal ejector levers to pull the
RTM ISDN card out of its slot in the backplane.
5 Carefully 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.
