hubs or LAN switches. A standard network cable is shipped with the Router
5012.
■
Crossover cable — The wire sequences of the twisted pair cable are terminated
by RJ-45 connectors that are different at either end. This type of cable can
connect terminal equipment, such as PCs and routers, to other terminal
equipment. You can create this kind of cable yourself, if necessary.
The 1-port 10/100 BASE-T SIC ships with the interface cables. While preparing
network cables, use the shielded cable first to ensure electromagnetic
compatibility.
To connect the Ethernet cable:
1
Power off the router.
2
If the Ethernet cable is a standard, straight-through cable, plug one end of the
cable into the Ethernet port of the 1-port 10/100 BASE-T SIC and the other end
into the hub or LAN switch.
3
Check the SLOT2 LED on the front panel of the router after you power on the
router. If the LED is on, the interface card has passed the power-on self-test
(POST). If the LED is off, the POST failed and you should contact your Service
representative.
4
Check the status of LINK LED on the 1-port 10/100 BASE-T SIC panel. If the LED is
on, the link is connected. If it is off, the link is not connected. Check the cables
and the connections.
1-Port Serial SIC
The main functions of the 1-Port Serial SIC are:
■
Transmisson and processing of synchronous or asynchronous serial data
streams
■
Operation in different modes, such as DTE/DCE, depending on the applications
■
Automatic detection of the type of external cable without manual
configuration
■
Local loop and remote loopback to facilitate fault testing and locating.
In different operating modes, a serial port supports different signal standards and
baud rates. The maximum transmission distance of the signals is related to the
baud rate setting. Table 13 lists the relations between cable type, baud rate setting
and signal transmission distance.
