Attention
In order to avoid improper use of equipment damage and personal injury,
please note the following:
1. During the installation, the power supply remains closed, while wearing
anti-static wrist, and ensure that anti-static wrist and skin good contact,
to avoid potential safety hidden danger;
2. The switch can work normally under the correct power supply. Please
confirm that the supply voltage is consistent with the voltage indicated
by the switch;
3. Before the switch is switched on, please confirm that it will not cause
overload of the power circuit, so as not to affect the normal operation of
the switch or even cause unnecessary damage;
4. In order to avoid the risk of electric shock, switch work should not open
the shell, even in the case of no electricity, do not open on its own;
5. Before cleaning the switch, the switch power plug should be pulled out,
please do not wipe with wet fabric, please don't use liquid cleaning;
6. Install the equipment rack generally from the bottom, avoid overload
installation;
7. The switch surface to avoid placing other heavy objects, so as to avoid
accidents.

Mounting Switch
Rack Mounting
1. Check the grounding and stability of the rack.
2. Secure the supplied rack-mounting brackets to each side of the device
with supplied screws, as illustrated in the following figure.
3. After the brackets are attached to the device, use suitable screws (not
provided) to secure the brackets to the rack, as illustrated in the
following figure.
Figure 2-1 Bracket Installation
Figure 2-2 Rack Installation
Desktop mounting
1. To install the device on the desktop, please follow the steps:
2. Set the device on a flat surface strong enough to support the entire
weight of the device with all fittings.
3. Remove the adhesive backing papers from the rubber feet.
4. Turnover the device and attach the supplied rubber feet to the recessed
areas on the bottom at each corner of the device.

Connect Port
Connect Ethernet port
Connect an Ethernet port of the switch to the device by RJ45 cable as the
following figure shows
Figure 3-1 Connect Ethernet port
Connect SFP port
The optical fiber module is grabbed from the side and inserted smoothly
along the switch SFP slot until the optical module is in close contact with
the switch.
Note: to avoid improper operation cause damage to equipment or personal
injury, please pay attention to the following matters
 Excessive bending of optical fibers is not allowed, and the radius of
curvature should not be less than 10cm.
 Ensure the cleanliness at the end of the fiber.
 Please do not look directly at the optical fiber connector; otherwise it
may cause damage to your eyes.
Remarks: it is recommended to adopt straight line -568B international
standard connection method, as the following figure shows
Power supply socket specification
Switch power line single-phase three wire power socket, the middle foot to
ground, and the left foot on the right foot for the zero line and FireWire,
please check before the operation.

Connecting to the Ground
The grounding cable is important to protect the switch from electrical
interference. It is advised to use the grounding cable; if your power is
ungrounded which could damage the switch or its functionality

Check after installation
Please check the following items after installation:
 check whether there is enough space for heat exchange, air circulation is
smooth
 check the power supply socket power supply switch is in accordance
with the specifications
 check the power supply, switchboard, rack and other equipment have
been properly grounded
Login the Device
The machine-default IP address is 192.168.2.11, subnet mask is
255.255.255.0. So when you log on to the switch, make sure the IP address
of the computer network card and the IP of the switch in the same network
segment: 192.168.2. *** (1 <*** <255, *** is not equal to 11).
Please enter user name: guest, password: guest, then you can use the web
browser-based configuration to manage switch.
