Connecting through an AUX cable
You need an AUX cable when configuring a router using a remote dial-up modem.
An AUX cable is an 8-core shielded cable. At one end of the cable is an RJ-45 connector. At the
other end is a DB-9 (male) connector. An AUX cable is the same as a console cable. For more
information, see
To connect the AUX port:
Plug the RJ-45 connector of the AUX cable into the AUX port of the router.
1.
Plug the DB-9 (male) connector at the other end into the serial port of the modem.
2.
Connecting through an Ethernet twisted pair cable
The 10/100/1000Base-T copper ports of the router support MDI/MDI-X autosensing. They are
connected to the network through Category 5 (or higher) twisted pairs equipped with RJ-45
connectors.
No Ethernet twisted pair cables are shipped with the router. Prepare them yourself.
To connect a 10/100/1000Base-T port:
Plug one end of an Ethernet twisted pair cable into the copper Ethernet port (RJ-45 port) to be
1.
connected on the router.
Plug the other end of the cable into the RJ-45 port of the peer device.
2.
Connecting through an optical fiber
Use an optical fiber to connect an optical fiber port (for example, XFP fiber port or SFP fiber port) on
the router to the network. You must install a transceiver module to the router, and then insert the fiber
connector into the module.
This section describes only the LC connector.
Figure 25 LC connector
Follow these precautionary steps:
When selecting a fiber network facility, make sure the type of the connector and the fiber match
1.
the adopted optical port.
Install the dust cover if the optical port is not connected to a fiber connector.
2.
Never stare at the optical port directly. Invisible rays may be emitted from the optical port if the
3.
optical port is not connected to a fiber connector or the dust cover is removed.
Never bend or curve a fiber when connecting it.
