1 SFP fiber interface (Fiber interfaces and gigabit electrical interfaces share the
MAC layer) on the FIC-16FSW module
DFIC-24FSW/DFIC-24FSW-PoE provides:
24 10/100 Mbps RJ45 connector interfaces on the DFIC-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. By default, the electrical interfaces
take effect.
The modules 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
Interface Attributes The interface attributes of the FIC-16FSW/DFIC-24FSW are given in the following
table:

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.
Interface LEDs FIC-16FSW/FIC-16FSW-PoE panel is shown in the following figure:
