MIM-16FSW/MIM-16FSW-PoE/DMIM-24FSW/DMIM-24FSW-PoE
Introduction
The 16/24-port 10/100 Mbps Ethernet Layer 2 switching MIM interface modules
(MIM-16FSW/MIM-16FSW-PoE and DMIM-24FSW/DMIM-24FSW-PoE) are applicable to MSR 30
series routers. A router installed with MIM-16FSW or DMIM-24FSW can work as a switching/routing
integrated device on a small-sized enterprise network to connect PCs and network devices inside the
network directly. MIM-16FSW-PoE/DMIM-24FSW-PoE can supply power to PDs through PoE.
The interfaces provided on the MIM-16FSW and DMIM-24FSW module are as follows:
z
16 × 10/100 Mbps RJ-45 connector interfaces on the MIM-16FSW module
z
24 × 10/100 Mbps RJ-45 connector interfaces on the DMIM-24FSW module
z
2 × 10/100/1000 Mbps (gigabit) RJ-45 connector electrical interfaces on the DMIM-24FSW module
z
2 × SFP fiber interfaces (Fiber interfaces and gigabit electrical interfaces share the MAC layer) on
the DMIM-24FSW module
The interface modules support:
z
100 meters (328.1 ft.) of transmission distance over the category-5 twisted-pair cable
z
100 meters (328.1 ft.) of transmission distance between any interfaces over the category-5
twisted-pair cable
z
Operation at 100 Mbps and 10 Mbps, autosensing
z
Full duplex and half-duplex, with the former in common use
z
24FSW provides two Combo interfaces as shown in Table 3-6 . By default, the electrical interfaces
take effect.
