MIM/DMIM/XMIM

For the modular MSR series routers, a wide range of optional MIM/DMIMs are available, which provide
abundant interfaces, such as synchronous/asynchronous serial interface, Ethernet interface, E1/T1,
ISDN BRI/PRI, audio interface, Layer 2 switching interface, and so on.

Among the Layer 2 switching interface modules, neither the XMIM-16FSW nor the XMIM-24FSW
supports the PoE function, while the MIM-16FSW and the DMIM-24FSW support the PoE function to
provide -48 VDC power to remote PDs (such as IP phone, WLAN AP, network camera) through
straight-through network cables as long as installed in a PoE router.

Introduction

DMIM-48FSW is a 48-port Ethernet Layer 2 switching MIM interface module, which can be installed on
the MSR 30 series. Each DMIM-48FSW provides 46 ordinary 10/100 Mbps RJ-45 connector interfaces
and two 10/100/1000 Mbps RJ-45 connector electrical interfaces. DMIM-48FSW is suitable for a small
enterprise network to serve as a switching & routing device, which can be directly connected to PCs and
network devices of the enterprise. DMIM-48FSW supports the following functions:

z

A transmission distance of 100 m (328.08 ft.) when connected with a category-5 twisted pair cable
(crossover or straight-through cable).

z

Wire-speed forwarding between any ports when connected with a category-5 twisted pair cable
(crossover or straight-through cable).

z

Auto-sensing at a rate of 10/100/1000 Mbps of the two GE interfaces.

z

Auto-sensing at a rate of 10/100 Mbps of the 46 FE interfaces.

z

Full duplex and half duplex, of which full duplex is common.
