Product mounting

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

Figure 4-4 Connecting Grounding Terminal

Note: The grounding bar and the ground cable are not provided with our

product. If needed, please self-purchase them.

Grounding Terminal

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

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.
