2.1.6. Gigabit Fiber SFP Interfaces
This product has two full-duplex 1000Base-LX single mode/ multi-mode
fiber interface, 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:
Hot-swappable SFP modules as follows:
Hot-plug procedure:
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.

2.1.7. Ethernet RJ45 Port
This product has multiple RJ45 10/100/1000Base-T Ethernet ports. Each
RJ45 port with auto-negotiation, auto MDI / MDI-X connection. Internet can be
used straight line/ cross-over cable to connect the switch to terminal equipment,
servers, hubs or other switches. Each port supports IEEE802.3x adaptive, so
the optimum transmission mode (half or full duplex) and data rate (10Mbps or
100Mbps) can be automatically selected (the connected devices must also
support this feature). If the device is connected to these ports do not support
adaptive, then the port will send the correct speed, but will default to half
duplex transmission mode.
Each RJ45 port supports 802.3af/at standard, single port maximum output
30W.

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.
2.2.5. Cable Layout
Before laying out the cables, check whether the specifications, models
and quantities of all cables are in conformity with the construction drawing
design and contract requirements;
Before laying the cable, check whether the cable is damaged, whether
there are factory records and quality assurance certificates that prove its
quality;
The specifications, quantity, routing direction, and location of the cables
to be laid should meet the design requirements of the construction drawings,
and the wiring length of each cable should be determined according to the
actual location;
The user cables and power cords are laid separately;
There must be no broken wires or joints in the middle of the laid cables;
Cables should be laid out neatly in the aisle, with even, smooth and

MISCOM7212GP Series Industrial Gigabit POE Switch
- 10 -
straight turns;
The cable should be straight in the trough, and should not go beyond
the trough to block other entry and exit holes. The cable should be tied and
fixed at the cable exit or the cable bend;
When cables, power cords, and ground wires are laid in the same slot,
the cables, power cords, and ground wires cannot be overlapped or mixed.
When the cable is too long, the cable must be neatly placed in the middle of the
cabling rack and cannot be pressed on other cables;
When laying pigtails, prevent the optical cable from knotting and
minimize the turning points, and the turning radius should not be too small. The
lashing should be moderately tight and not too tight. When laying on the cable
rack, it should be placed separately from other cables;
Both ends of the cable should have corresponding marks, and the
content of the marks is concise and 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.
