Gigabit fiber SFP interfaces
This product has two full-duplex 1000Base-LX single mode / multimode
fiber interface, the port number for the G1 and G2, using hot-swappable SFP
during the optical interface using LC connectors. Optical interface to be used in
pairs (TX and RX as a pair), TX mouth to light the originator, the remote switch
connected to another optical interface of the light receiving end RX; RX ports
for the light receiving end, to connect with a remote switch with an optical
interface light originator TX. The use of two redundant 1000Base-LX optical
interface fiber optic redundant ring network can be formed in the system failure
redundant ring switching time less than 20ms, can effectively improve network
reliability.
SFP optical module shown in the figure :

2.2. Hardware Installation
2.2.1. Installation notice
The Industrial Ethernet switch is used standard 35mm DIN-Rail
install.Please make sure a suitable work environment, including power
requirements, enough space, connect equipment and other equipment status.
Please confirm the following installation requirements:
Power supply: Standard DC24V power supply
Environmental requirements: Temperature -40°C ~ 70°C, relative
humidity 0 ~ 95% (no condensation).
Grounding resistance requirement:<5
Configuration requirements under the contract, check the cable is in
place, fiber optic connectors is appropriate.
Avoid direct sunlight and awayfrom heat sources or areas with strong
electromagnetic interference.
Standard 35mm DIN-rail installation. Check for suitable cables and
connectors.
Attention
Before installing or connecting Ethernet switch please make ensure that
disconnect the power line. Do not exceed Max. current. If exceeds the
maximum current, make the wire overheat, causing serious damage to the
equipment.
Separate the power cable and other cables, if the two paths must cross,
must ensure that the intersection of these lines are vertical.
Grounding and cabling can effectively suppress the noise caused by
electromagnetic interference. Before connect the switch with equipment
please connect GND first. Connected to the grounding screw from the
ground surface.

2.2.2. Installation
This series equipment back panel have fixed well DIN rail-way connection
seat. If need installation, please check DIN rail way condition .
2.2.3. Cable connection
After install Ethernet switch , please correct install cable. The switch
10/100/1000Base-TX RJ45 interface ports, use the crossover cable direct
connect with terminal equipment , use cross wire connect network equipment .
2.2.4. Fiber connection
This switch use 1000Base-LX single mode or multi-mode fiber connector.
When use fiber cable port, remove port cover; When it finish work,
please put the plastic cover to protect the fiber optic head, keep clean.
Check the fiber optic cable head whether it clean or not. If it not clean,
will effect port and communication quality.
One fiber optic head connect with Ethernet switch optic port, the other
fiber head connect with another equipment fiber optic interface equipment.
After connection, please check switch the front interface’s LNK/ACT LED
lights. If lights on, connection is available.
Hot-swappable SFP modules as follows:
Hot-plug procedure:

MISCOM7212G Series Industrial Ethernet Switch
- 9 -
1.SFP during the observation of a finger end of the PCB.
2.the finger end into the SFP metal shielding cage, hear a click sound
indicates that the device has been inserted in place, then the SFP plug handle,
into the interface parallel to the normal position, you can use.
Hot drawing steps:
1.first unplug the SFP's plug handle perpendicular to the interface, this
time the device should be shielded with SPF cage mount hook disengaged.
2.parallel to pull the SFP module.
2.2.5. Cable Layout
Laying of cable should as following conditions:
Before laying cable please checking whether suitable for project.
Before laying cable laying please checking quantity, route to, location an
other related , construction design whether suitable. Separate users cable and
power supply cables.
Please check the cable do not broken or other connector.
Fiber optic cable should be straight in the aisles neatly inside, turning
uniform, smooth and straight.
cable in the channel, it should be straight, not close to channel, blocking
the other inlet and outlet holes in the cable channel out of the corner site or
cable should be binding and fixed.
Do not mix cable, power cable, GND cable. Do not overlap.
If cable is too long, it must be structured cable support rail site on the
middle, do not pressure the cable.
It is necessary to prevent the cable too tie and turns should be minimized,
turning radius should be suitable. Banding should be appropriately tight, not
too tight.
Cable should be the appropriate identity, easy to maintain.
Attention:
Laying cable, it is necessary to prevent the cable tie and turns should be
minimized, and the turning radius is not too small, the turning radius is too
small will lead to a serious loss of optical signal link. The quality of
communication.
2.3. Simple Testing guide
2.3.1. Self-examination
When connection equipment, the front panel power supply indicator light
will blinking once, it means working well. After a while Power supply indicator
light is on. Run indicator light (system status LED) will blink interval.

2.3.2. RJ45 port testing
As picture show, the power port by any two straight lines and two test
networked computers connected to the network port, send a Ping command to
each other, both sides were able to correctly Ping to each other without loss.
That tested the hardware working properly the two power ports.
2.3.3. Fiber optic port testing
Composed of two devices as shown in the optical chain network. Each
device port by any one power line and testing of computer networking directly
connected to each other and send the Ping command, both to each other and
do not correctly Ping packet loss. While the corresponding optical port Link /
Act LED should be lit. Two optical ports that the hardware is tested working
properly. Another way to test using the same optical port.
