SW-2GT-2SFP
4-Port Gigabit Switch
USER MANUAL
Brief introduction
SW-2GT-2SFP is a 4 port Gigabit Ethernet Switch with 2 10/100/1000M
Ethernet ports and 2 SFP 1.25G SFP slots. End users can use different SFP
modules such as 1000Base-T, 1000Base-SX, 1000Base-LX etc. The switch supports
IEEE802.3U IEEE802.3z 1000Base-Tx/Fx protocol, as well as full duplex and half
duplex mode.
For optical SFP transceivers, this switch supports any third-party standard SFP
modules from any SFP vendors.

Installation
1. Interface
RJ-45 interface
The transmission media adopts CAT5 twisted-pair with typical length of 100 meters. It
features the function of automatically identifying the through line and cross wires. Fiber
interface LC is of duplex mode type, including two interfaces, namely TX and RX.
When the two sets of optical transceivers are interfaced or connected to switch, the fiber
is in cross connection, namely "TX-RX", "RX-TX" (direct butting for single optical
fiber).
2. Connection
The network device (work station, hub or switch) with RJ-45 interface is connected to
RJ-45 jack through twisted-pair.And the multi/single mode fiber is connected to SFP
module LC fiber connector. Then optical transceiver works and the corresponding LED
is ON for correct connection. (See the table below for the LED indicators:)
Explanation for LED indicators
LED indicators serve as device monitoring and trouble display. The following is the

explanation for each LED indicator.
LED
Status
Explanation
Link/Act
On
Connection status display for link.
“ON”indicates that link is in correct connection.
Blink
Active status display of fiber port or RJ45 port
“Blink”indicates packet goes through switch correctly.
PWR
On
Power is On and normal.
1000M
On
Transfer rate of electric interface is 1000Mbps.
Notice:
VLAN: TP 1 and TP2 port isolation mode
NORMAL:All port switching mode

Cautions:
1. This product is suitable for indoor application.
2. Put on the dust cover of fiber interface when not used.
3. It is forbidden to stare at the TX fiber-transfer end with naked eyes.
4. Single optical fiber or WDM transceiver must be used in pair..
Trouble shooting:
1. Device is not matched. Please select the corresponding network device according to the transfer rate
of the product (10Mbps or 100Mbps, 1000Mbps) when connected to other network devices (network
card, hub, switch).
2. Line loss is excessive during the fiber wiring. Excessive loss in connector plug-in and fiber soldering
and excessive intermediate nodes may cause excessive loss rate or abnormal operation.
