3.2 Mounting Modes and Steps
The series switches support rack mounting by front/rear panel. The following uses mounting
by front panel as an example to describe mounting steps. The steps for mounting by rear
panel are similar to those for mounting by front panel. Before installation, make sure that the
following requirements are met.
1) Environment: temperature (-20℃to 60℃), ambient relative humidity (5% to 95%,
non-condensing)
2) Power requirement: The power input is within the voltage range of the switch.
3) Grounding resistance: <5
4) No direct sunlight, distant from heat source and areas with strong electromagnetic
interference.
5) Devices are to be installed in an authority certified enclosure and accessible only by the
use of a tool.
6) Devices should be installed and accessed by service personnel or users who have been
instructed about the reasons for the restrictions applied to the location and about any
precautions that shall be taken.
Installing Mounting Brackets
The mounting brackets for this series switches support two mounting positions, as indicated
by the two dashed boxes in the following figure. You can select either of the mounting
positions as needed.

brackets. If there are screws inserted in the screw holes, remove the screws and keep them
for future use.
As shown in the following figure, use four screws to secure two mounting brackets to the
switch respectively.

Mounting
Step 1: Select the mounting position for the switch and guarantee adequate space and heat
dissipation (house dimensions: 440mm×44mm×325mm).
Step 2: Move the switch in direction 1 until the screw holes for securing the mounting
brackets to rack posts are in alignment with the corresponding holes in the rack
posts. Then use four screws and supporting captive nuts to secure the mounting
brackets to the rack posts.
Dismounting
Step 1: Remove the four screws and supporting captive nuts securing the mounting brackets
to the rack posts.
Step 2: Remove the switch from the rack posts. Then unscrew the mounting brackets to
complete dismounting.
Caution:
Cut off the power and disconnect all cables before mounting, dismounting or moving the
equipment.

The mounting brackets can only fix the switch and can not bear the load. Please
select a rack with a tray or rail for installation.
In a high vibration environment, the front and rear panels of the device are
secured to the rack at the same time to ensure safe use. Only two mounting
brackets are available. Additional mounting flanges are optional.

used in pairs. For example, modules 7 and 8 are single-mode and LC-interface modules with a
transmission distance of 20 km. For the central wavelength of module 7, the transmitting end is
1310 nm and the receiving end is 1550 nm. For the central wavelength of module 8, the
transmitting end is 1550 nm and the receiving end is 1310 nm. Therefore, modules 7 and 8 can be
used in a pair.
Figure 8 Gigabit SFP Optical Module
An SFP optical module is equipped with LC connector, and each port consists of a TX
(transmit) port and an RX (receive) port. To enable communication between Device A and
Device B, connect the TX port of Device A to the RX port of Device B, and the RX port of
Device A to the TX port of Device B, as shown in the following figure.
Figure 9 Fiber Connection of an SFP Optical Module
How to Connect the SFP Optical Module
Insert the SFP optical module into the SFP slot in the switch, and then insert the fibers into
the TX port and RX port of the SFP module.
Figure 10 Connecting the SFP Optical Module

Connection
13
Identify the RX port and TX port of an SFP optical module:
1. Insert the two connectors in one end of two fibers into the SFP module, and those in the
other end into the peer module.
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, swop the two
connectors at one end of the fibers.
Caution:
The device uses laser to transmit signals in fibers. The laser meets the requirements of level 1
laser products. Routine operation is not harmful to your eyes, but do not look directly at the
fiber port when the device is powered on.
If the defined transmission distance of an SFP module is longer than 60km, do not use a short
fiber (<20km) for connection. If such a short fiber is used, the module will be burned.
4.3 1000Base-X, 10/100/1000Base-T(X) Combo port
As shown in following table, the 1000Base-X, 10/100/1000Base-T(X)Combo port consists of
one 1000Base-X port(GX) and one 10/100/1000Base-T(X) Ethernet port, and only one of
the two ports can be used at one time, and the 1000Base-X port has priority over
10/100/1000Base-T(X) port. Plug the optical fiber and the twisted pair into GX and GE
respectively; GX can communicate normally and the GE will be disabled automatically.
The following table lists the relation of Gigabit SFP ports of Combo port and the
corresponding 10/100/1000 Base-T(X) Ethernet port.

4.6 Grounding
Grounding protects the switch from lightning and interference. Therefore, you must ground
the switch properly. You need to ground the switch before it is powered on and disconnect
the grounding cable after the switch is powered off.
The switch provides a grounding screw(see Figure 2) on the rear panel for chassis
grounding. After crimping one end of the grounding cable to a cold pressed terminal, secure
the end to the grounding screw and connect the other end to the earth firmly.
Note：
Cross-sectional area of the chassis grounding cable>2.5mm2; grounding resistance<5.

4.7 Power Terminal Block
There is a power terminal block on the rear panel of the device. You need to connect the
power wires to the terminal block to provide power to the device. The device supports single
(PWR1) and redundant (PWR1 and PWR2) power supply with a 5-pin 5.08mm-spacing
plug-in terminal block. When the redundant power supply is used and one power input is
faulty, the device can continue operating properly, thereby improving network reliability.
Note：
0.75mm2<Cross-sectional area of the power wire<2.5mm2; grounding resistance<5.
