FIC-16FSW/FIC-16FSW-PoE/DFIC-24FSW/DFIC-24FSW-PoE 211
In addition, there is a POE LED on each card, which is provided for the
corresponding boards (FIC-16FSW-PoE and DFIC-24FSW-PoE) with the PoE
function.
nThe two GE interfaces on the DFIC-24FSW-PoE do not support the PoE function.
Interface Cable Normally, category-5 twisted pair cable is adopted to connect the 10BASE-T
/100BASE-TX Ethernet interface to the Ethernet, as shown in the following figure:
Figure 258 Ethernet cable
Ethernet cables fall into two categories: straight-through cables and crossover
cables, specifically,
■Straight-through cable: The sequences of the twisted pairs crimped by RJ-45
connectors at both ends are the same. It is used for the connection between a
terminal device (e.g., PC and router) and a Hub/LAN Switch. The cables
delivered with the Router are straight-through cables.
■Crossover cable: The sequences of the twisted pairs crimped by RJ-45
connectors at both ends are different. It is used for the connection between
terminal devices (e.g., PC and router). And it can be made by the user.
For the pinouts of straight-through Ethernet cable and crossover Ethernet cable,
see Low-End and Mid-Range Series Routers Cable Manual.
Connecting the Interface
Optic Fiber
Connecting Ethernet fiber interface cable
cCAUTION: When connecting the optical fiber, observe the following
■Do not over-bend the optical fiber. Its curvature radius must be no less than 10
cm (3.9 in).
■Ensure that the Tx and Rx ends are correctly connected.
