The back panel consists of 2 DC power inputs, 1 AC Input, 1 Relay Output.

2.2 Wiring Power Inputs

The switch provides two types power input, AC power input and DC power input. It

also provides redundant or aggregated power inputs, depending on the voltage of

power input. If there are over two power inputs are connected with different

voltages, it will be powered from the highest connected voltage (redundant power).

If the voltages of power inputs are the same, the total power output will be

aggregated (aggregaged power).

AC Power Input

Connect the attached power cord to the AC power input connector, the available AC

power input is range from 90-264VAC.

High Voltage Power Input

The power input support both 90-264VAC and 127-370VDC power input. Connect

the power cord to the PE for Protective Earth, L / V+ for LINE or V+, N/V- for Neutral

or V-. For high power input, tighten the wire-clamp screws to prevent DC wires from

being loosened is must.

DC Power Inputs

The range of the available DC power input is from 46-57VDC. In the IEEE802.3at

mode, the PoE power output is 50~57 VDC, 0.6A, therefore, the suggested DC power

input ranges is 52~57V. In the IEEE802.3af mode, the PoE power output is 44~57

VDC, 0.35A, therefore, the suggested DC power input is 46~57VDC.

If the DC power input is 53V, the unit will aggregate the power with the AC power

2.6 Wiring Fast Ethernet Ports

The switch includes up to 24 RJ-45 Fast Ethernet ports. The Fast Ethernet ports

support 10Base-T and 100Base-TX, full or half duplex modes. All the Fast

Ethernet ports will auto-detect the signal from connected devices to negotiate

the link speed and duplex mode. Auto MDI/MDIX allows users to connect

another switch, hub or workstation without changing straight through or

crossover cables.

Note that crossover cables simply cross-connect the transmit lines at each end

to the received lines at the opposite end.

Note that Ethernet cables use pins 1, 2, 3, and 6 of an 8-pin RJ-45 connector. The

signals of these pins are converted by the automatic MDI-X function, as shown in

the table below:

Connect one side of an Ethernet cable into any switch port and connect the

other side to your attached device. The LNK LED will light up when the cable is

correctly connected. Refer to the LED Indicators section for descriptions of each

LED indicator. Always make sure that the cables between the switches and

attached devices (e.g. switch, hub, or workstation) are less than 100 meters (328

feet).

The wiring cable types are as below.

10Base-T : 2-pair UTP/STP Cat. 3, 4, 5 cable, EIA/TIA-568 100-ohm (100m)

100Base-TX: 2-pair UTP/STP Cat. 5 cable, EIA/TIA-568 100-ohm (100m)

4.2.3 IP Configuration

This function allows users to configure the switch’s IP address settings.

DHCP Client: You can select to Enable or Disable DHCP Client function. When

DHCP Client function is enabled, an IP address will be assigned to the switch from

the network’s DHCP server. In this mode, the default IP address will therefore be

replaced by the one assigned by DHCP server. If DHCP Client is disabled, then the

IP address that you specified will be used instead.

IP Address: You can assign the IP address reserved by your network for your

switch. If DHCP Client function is enabled, you don’t need to assign an IP address

to the switch, as it will be overwritten by DHCP server and shown here. The default

IP is 192.168.2.200.

Subnet Mask: You can assign the subnet mask for the IP address here. If DHCP

Client function is enabled, you don’t need to assign the subnet mask. The default

Subnet Mask is 255.255.255.0.

Note: In the CLI, we use the enabled bit of the subnet mask to represent the

number displayed in web UI. For example, 8 stands for 255.0.0.0; 16 stands for

255.255.0.0; 24 stands for 255.255.255.0.

Default Gateway: You can assign the gateway for the switch here. Note: In CLI, we

use 0.0.0.0/0 to represent for the default gateway.

Once you finish configuring the settings, click on Apply to apply your configuration.

IPv6 Configuration –An IPv6 address is represented as eight groups of four

hexadecimal digits, each group representing 16 bits (two octets). The groups are

separated by colons (:), and the length of IPv6 address is 128bits.

An example of an IPv6 address is: 2001:0db8:85a3:0000:0000:8a2e:0370:7334.

The default IP address of Managed Switch is fe80:0:0:0:212:77ff:fe60:ca90, and

the Leading zeroes in a group may be omitted. Thus, the example address may be

written as: fe80::212:77ff:fe60:ca90.

IPv6 Address field: typing new IPv6 address in this field.

Prefix: the size of subnet or netwok, and it equivalent to the subnetmask, but

writtenin different.The default subnet mask length is 64bits, and writen in

decimal value -64.

Add: after add new IPv6 address and prefix, don’t forget click icon-“Add”to apply

new address to system.

Remove: select existed IPv6 address and click icon-“Remove”to delete IP address.

Reload: refresh and reload IPv6 address listing.

IPv6 Default Gateway: assign the IPv6 default gateway here.Type IPv6 address of

the gateway then click “Apply”. Note: In CLI, we user ::/0 to represent for the IPv6

default gateway.

IPv6Neighbor Table: showsthe IPv6 address of neighbor, connected interface,

MAC address of remote IPv6 device, and current state of neighbor device.

The system will update IPv6 Neighbor Table automatically, and user also can click

the icon “Reload” to refresh the tabale.

4.2.4 Time Setting
