2.15.5 Connecting the Interface Cable
Caution:
When connecting the optical fiber, observe the following:
z
Do not over-bend the optical fiber. Its curvature radius must be no less than 10 cm
(3.9 in).
z
Ensure that the Tx and Rx ends are correctly connected.
z
Ensure that the fiber ends are clean.
Warning:
Laser danger: Invisible laser radiation may be emitted from the fiber-optic ports which
are connected to lasers. To protect your eyes against radiation harm, never stare into
an open fiber-optic port.
Step 1: Insert the SFP optical module into its corresponding slot.
Step 2: Locate the Rx and Tx ports of the SIC-1FEF interface. Connect them to another
device with two optical fibers: Rx to Tx and Tx to Rx.
Step 3: Power on the router and check the behavior of the LINK LED on the SIC-1FEF
panel. ON means an Rx link is present and OFF means the opposite. In the latter case,
check the line status.
2.16 SIC-8AS
2.16.1 Introduction
SIC-8AS, the 8-port asynchronous serial interface card, is mainly used to transceive
and process the asynchronous data streams.
SIC-8AS has these features:
z
Each asynchronous serial port provides a rate up to 115.2 Kbps.
z
Supports the terminal access service and asynchronous dedicated line.
z
Serves as the small-/medium-sized ISP dial-up access server when an
asynchronous serial port is used for dial-up.
