2.6 Wiring Fiber Ports
Small Form-factor Pluggable (SFP)
The SFP ports fulfill the SFP standard. To ensure the system reliability, it is
recommended to use the approved Gigabit SFP Transceiver. The web user
interface will show Unknown vendor type when choosing the SFP which is not
approved.
The way to connect the SFP transceiver is to Plug in SFP fiber transceiver fist.
Cross-connect the transmit channel at each end to the
receive channel at the opposite end as illustrated in the figure
below.
Note: This is a Class 1 Laser/LED product. Don’t look into the Laser/LED Beam.
2.7 Wiring Gigabit Combo Ports
The switch includes RJ-45 Gigabit Combo ports. The speed of the Gigabit
Ethernet copper port supports 10Base-T, 100Base-TX and 1000Base-TX. The
speed of the SFP port supports 1000Full Duplex.
2.8 Wiring RS-232 Console Cable
The switch attaches one RS-232 DB-9 to RJ-45 cable in the box. Connect the RJ-45
connector to the COM port of your PC, open Terminal tool and set up serial
settings to 9600, N,8,1. (Baud Rate: 9600 / Parity: None / Data Bit: 8 / Stop Bit: 1)
Then you can access the CLI interface using console cable.
Note: If you have lost the cable, please contact your local sales or follow the pin
assignment to buy/make a new one. The pin assignment spec is listed in the
appendix.
