Connection
Figure 10 Connecting the SFP Optical Module
Confirm the RX port and TX port of an SFP optical module:
1. Insert the two connectors at one end of fibers into the two interfaces of SFP module, and
then insert the two connectors at the other end of fibers into the two interfaces at the
corresponding end.
2. View the corresponding connection status LED: If the LED is on, the connection is
correct. If the LED is off, the link is not connected. This may be caused by incorrect
connection of the TX and RX ports. In this case, swap the two connectors at one end of the
fibers.
Caution:

The device uses laser to transmit signals over fiber. The laser meets the requirements of level
1 laser products. Do not look directly at the fiber port to avoid to harm to your eyes when device
is powered on.

For SFP module which transmission distance is longer than 60km, do not use a short fiber
(<20km) to connect to avoid the SFP module is brunt since the optical power is saturation.
4.4 Console Port
4.4.1 RJ45 Console Port
Connect the 9-pin serial port of a PC to the console port of the switch with a DB9-RJ45
console cable. Then you can configure, maintain, and manage the switch by running Hyper
Terminal in Windows OS.
