144 CHAPTER 3: MULTIFUNCTIONAL INTERFACE MODULES
n
Ethernet interfaces on network adapters are usually medium dependent interfaces
(MDIs). Cross medium dependent interfaces (MDIXs) are another type of Ethernet
interfaces, which are usually used on hubs and LAN Switches.
Interface LEDs Figure 165 shows the XMIM-16FSW panel.

Figure 166 shows the XMIM-24FSW panel.
Figure 166 XMIM-24FSW panel
Each 10/100 Mbps Ethernet interface on the panel has two corresponding LEDs.
One is yellow and the other is green. Table 101 describes these LEDs.

XMIM-16FSW and XMIM-24FSW are both 1U (44.45 mm, namely, 1.75 in.) in
height and each occupy two slots (the upper slot and the lower slot).
Interface Cable 10BASE-T, 100BASE-TX, and gigabit Ethernet interfaces are connected to Ethernet
networks with Ethernet cables, usually category-5 twisted pair cables. Figure 167
shows the appearance of an Ethernet cable.
