IPS DMR Modular Chassis (MC)

There are 2 types of MODULAR CHASSIS; "Physical MODULAR CHASSIS" and "Virtual MODULAR CHASSIS ". The Physical MODULAR CHASSIS is a “hardware MODULAR CHASSIS” and is used to accommodate an MP, IP PADs, legacy LT/AP cards, and power supply units. The IPS DMR can consist of one or two MODULAR CHASSIS depending on the system configuration. The Physical MODULAR CHASSIS provides 56 LT ports in hardware slots and provides 64 ports in software port allocation (56LT ports and 8 virtual ports). The Virtual MODULAR CHASSIS is a “software MODULAR CHASSIS” with a port capacity of 64 ports. A maximum of two Virtual MODULAR CHASSIS can be assigned per remote site for a total of 128 ports used to accommodate IP stations by system data programming. The maximum number of Remote Sites is 30. This system allocates the maximum of 64 FP/AP cards per system, at multiple Remote Sites. The number of FP/AP cards accommodated at one Remote Site should be a maximum of eight including the MP with built-in FP. If more than eight FP/APs are assigned, the system does not operate normally.

The following illustration shows MODULAR CHASSIS hardware configurations, software port allocation, face layout and rear view of MODULAR CHASSIS for IPS DMR.
