Quidway Eudemon 200 Firewall Chapter 7 Interface Module

z Crossover cable: The wire sequences of the twisted pairs crimped in the RJ-45
connectors at both ends are different. It is used for connecting two terminal
devices (e.g., PC and router). Users can make it as needed.
For the pinouts of straight-through Ethernet cable and crossover Ethernet cable, please
refer to Appendix A.
Note:
When preparing network cables, please use shielded twisted-pair (STP) cables so long they are available
for the sake of electromagnetic compatibility.
7.4.5 Connect Interface Cable
Step 1: If the Ethernet cable is a straight-through cable, plug one end of the cable into
an Ethernet port on the FE card, and another end to a HUB or LAN Switch.
Step 2: Power on the firewall and check the status of the LINK LED on the FE panel.
ON means that the link has been connected and OFF means that the link is not
connected. In the latter case, check the line.
Caution:
You must connect a cable to the interface with the appropriate mark. Misplugging is prone to impair the
interface card and even damage the router mainframe.
7.5 1MFX/1SFX
7.5.1 Introduction
1MFX provides one 100Mbps Ethernet multi-mode fiber interface.
1SFX provides one 100Mbps Ethernet single-mode fiber interface.
The high reliability and sound transmission quality intrinsic to optical fibers enable
1MFX and 1SFX to easily accomplish the communications between the firewall and a
LAN. The interface can work in megabit full-duplex mode.
