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
Figure 4 Mounting Bracket
You can select the screw holes for front or rear panel mounting to install the mounting
brackets. There is a group of screw holes on the front and rear panels on both sides of the
device respectively. In each group of screw holes, three large screw holes (M4) are used to

install the mounting brackets, other small screw holes (M3) are used to fasten gaskets. If
there are screws inserted in screw holes (M4), remove the screws and keep them for future
use.
As shown in the following figure, use three screws to secure two mounting brackets to the
switch respectively.
Figure 5 Installing Mounting Brackets
Mounting
Step 1: Select the mounting position for the device and guarantee adequate space and heat
dissipation for it (dimensions: 440mm×88mm×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.

Figure 9 Gigabit SFP Optical Module
Gigabit 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 (transmit) port of Device A to the RX (receive) port of Device B,
and the RX (receive) port of Device A to the TX (transmit) port of Device B. The following
figure shows the cable connection of the Gigabit SFP optical module.
Figure 10 Cable Connection of Gigabit SFP Optical Module
How to Connect the SFP Optical Module
Insert the SFP optical module into the SFP slot in the switch, and then plug the optical fiber
into the TX port and RX port of the SFP module.
Figure 11 Connecting the Gigabit SFP Optical Module
How to Determine the RX Port and TX Port of Gigabit SFP Optical Module
1. Insert the two connectors in one end of optical fiber into the gigabit SFP module, and
those in the other end of the optical fiber into the SFP module of another switch.
2. View the corresponding port connection status LED in the front panel: If the LED blinks,
the link is connected. 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 in the
one end of the optical fiber.
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 SFP 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 SFP port has priority over
10/100/1000Base-T(X) Ethernet 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.

4.5 Console Port
There is a Console port on the front panel of the switch, as shown in Figure 12. Connect the
9-pin serial port of a PC to the console port of the switch with a DB9-RJ45 console cable.
You can configure, maintain, and manage the switch by running Hyper Terminal in the
Windows OS of a computer.

4.6 Grounding
Grounding protects the device from lightning and interference. Therefore, you must ground
the device properly. You need to ground the device before it is powered on and disconnect
the grounding cable after the device is powered off.
There is a grounding screw(see Figure 2) on the top panel of the device. The screw is for
chassis grounding. After crimping one end of the grounding cable to a cold pressed terminal,
secure the end to the grounding screw and firmly connect the other end to ground.
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 switch. You need to connect the
power cable to the terminal block to provide power for the switch.
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 supply is faulty, the switch can continue operating properly, thereby improving
network reliability.

not use pins 4 and 5.
Wiring and mounting
Step 1: Ground the switch properly according to section 4.6.
Step 2: Remove the power terminal block from the switch.

Step 3: Insert the power cable into the power terminal block according to Table 9 to fix the
power cable.
Step 4: Insert the terminal with the connected cable into the terminal block on the device.
Step 5: Connect one end of the power cable to an external power supply system (with the
allowed power range). If the power LED on the front panel of the switch turns on, the
power supply is connected properly.
Caution:
Before connecting the device to power supply, make sure that the power input meets the power
requirement. If connected to an incorrect power input, the device may be damaged.
Warning:
Do not touch any exposed conducting wire, terminal, or component with a voltage warning
sign, because it may cause personal injury.
Do not remove any part or plug in or out any connector when the device is powered on.
4.8 Alarm Terminal Block
The alarm terminal block is used for alarm output. When the switch works properly, the
normally-open contacts of the alarm relay are closed and the normally-closed contacts are
open. When an alarm occurs, the normally-open contacts are open and the normally-closed
contacts are closed. The alarm is outputted through a 3-pin 5.08mm spacing terminal block,
as shown in Figure 15.
