24 10/100 Mbps RJ45 connector interfaces on the DMIM-24FSW module

2 10/100/1000 Mbps (gigabit) RJ45 connector electrical interfaces on the DMIM-24FSW module

2 SFP fiber interfaces (Fiber interfaces and gigabit electrical interfaces share the MAC layer) on the DMIM-24FSW module

The interface cards support:

100 meters (328.1 ft.) of transmission distance over the category-5 twisted-pair cable

100 meters (328.1 ft.) of transmission distance between any interfaces over the category-5 twisted-pair cable

Operation at 100 Mbps and 10 Mbps, autosensing

Full duplex and half-duplex, with the former in common use

24FSW provides two Combo interfaces as shown in Table 86. By default, the electrical interfaces take effect.

n MDI stands for Media Dependent Interface of the Ethernet. Normally, the interfaces on the network cards belong to this type. MDIX stands for Cross Media Dependent Interface, which is usually adopted on hubs or LAN switches.
