Replacing a Faulty MPM+ Card
Removing the MPM+ Card from the MCU
All MPM+ cards can be installed or removed while the RMX 4000 is
powered on and operating.
Prior to removing an MPM+ 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.
It is recommended that the air filter be replaced or cleaned every six months.
