both) RTM ISDN/RTM LAN card(s). In order for an MPM+ card to
function (i.e. video) one of the RTM boards, either a LAN or ISDN card
MUST be present in a rear panel slot opposite to an MPM+ card.
A single RTM-IP 4000 card must also be located on slot 17 in the rear of
the RMX 4000. In addition, the rear panel houses the main AC power
switch, AC Power Entry Modules (PEMs) or DC Power Rail Modules
