Component Replacement

The RMX 4000 is designed with ease of maintenance in mind. Most components are swappable and are accessible directly via the front panel

or the rear panel.

The MPM+, RTM ISDN, power supplies and Fan tray are Hot Swappable. The Fan tray must be replaced immediately or the temperature spike in the RMX shall initiate a shutdown. The RTM-IP 4000, RTM LAN, Fabric Switch Module (FSM) 4000 and the CTNL 4000 are not Hot Swappable. System shutdown is required when replacing the RTM-IP 4000, RTM LAN, FSM 4000 and the CTNL 4000.
