eight 10/100/1000M PoE+ ports, eight 10/100/1000M RJ45 ports and four Gigabit SFP slots for highly
critical PoE applications such as real time IP video surveillance, WiMAX systems and Wireless APs. All 8
PoE ports of the switch are compliant with both IEEE 802.3af PoE and IEEE 802.3at high power PoE
standards and can deliver up to 15.4W and 30W power per port to enable the high-power requiring
devices, such as Wireless APs, PTZ and dome network cameras, etc.
Ethernet Ring Protection Switching (ERPSv2)
Ring network topology ensures the reliability of the connections among all the switches in the network.
This switch supports ERPSv2 with easy to set up user interface, which allows it to recover from network
disconnection in less than 20ms with 250 switches connected in a ring network topology while
transmitting/receiving data at full network speed. Also, this switch supports multiple ERPS instances,
allowing different VLANs have their own ERPS instances.
USB Port for Save/Restore Configuration & System Log/Firmware Storage
This switch comes with a USB port for connecting a USB storage device to the industrial switch.
Configuration files, switch system log and firmware can be stored in the USB storage device for the
switch to access. When a USB storage device is connected to the switch, it will load the configuration file
in the storage device and apply all the settings, saving on-site installation time and effort.
Redundant Power Inputs & Embedded Protecting Circuit
This switch provides two power inputs that can be connected simultaneously to live DC power source. If
one of the power input fails, the other live source acts as a backup to automatically support the switch’s
power needs without compromising network service qualities. Also, it supports automatic protection
switching and load balance, while its embedded protecting circuit can protect your system from over
input/output voltages and rectifier malfunctions.
Outstanding Management and Enhanced Security
This switch provides various network control and security features to ensure the reliable and secure
network connection. To optimize the industrial network environment the switch supports advanced
network features, such as Tag VLAN, IGMP Snooping, Quality of Service (QoS), Link Aggregation Control
Protocol (LACP), Rate Control, etc. The PoE switch can be smartly configured through Web Browser,

II-3. Preparation for Telnet/SSH Interface

Both telnet and SSH (Secure Shell) are network protocols that provide a text-based command line
interface (CLI) for in-band system management. However, only SSH provides a secure channel over an
un-secured network, where all transmitted data are encrypted.
This switch support both telnet and SSH management CLI. In order to access the switch’s CLI via telnet or
SSH, both your PC and the switch must be in the same network. Before using the switch’s telnet/SSH
management CLI, please set your PC’s network environment according to the previous chapter (II-2.
Preparation for Web Interface).
Telnet interface can be accessed via Microsoft “CMD” command. However, SSH interface can only be
accessed via dedicated SSH terminal simulator. The following section will use PuTTY as an example to
demonstrate how to connect to the switch’s SSH CLI, since both telnet and SSH uses the same way
(though using different terminal simulator software) to access in-band management CLI.
Access SSH via Putty:
A “PuTTY Configuration” window will pop up after you run PuTTY.
1. Input the IP address of the switch in the “Host Name (or IP address)” field. The default IP address
of the switch is 192.168.2.1.

III-2-3. BASIC SETTINGS – IPV6 SETTINGS

Internet Protocol Version 6 (IPv6) is a solution to deal with the address space limitation of IPv4 and it is
the most recent version of Internet Protocol. It is intended to replace IPv4. IPv6 is a Layer 3 (Internet
Layer) protocol, which is used on the packet-switched networks and with connectionless communication.
There are 16 bytes (128 bits) for an IPv6 address and the address space is up to 2
The IPv6 address is usually represented in hexadecimal digits, 8 groups of 4 digits, and each group is
separated by a “:” (colon). For example, the DNS server address in IPv6 is
“2001:4860:4860:0000:0000:0000:0000:8888”.

III-2-3. BASIC SETTINGS – SYSTEM TIME

The System Time represents the date and time. The system uptime defines the passing time after the
system boots up. There is no battery on the switch and hence the system time cannot be saved in the
system. Users can configure the time zone and system time manually by synchronizing the time with the
browser or by enabling the “NTP” service to get the time from a NTP Server.
NTP
Network Time Protocol (NTP) is a clock synchronization protocol, which is used to synchronize the
system time with the NTP server. NTP is one of the oldest Internet Protocols in use from 1985 until now.
It works based on a client-server model, but it can also be used in peer-to-peer relationships. The NTP
application on the switch is follows the client-server model and the switch plays a role in the NTP Client.

III-3. Web Management – Redundancy

III-3-1. REDUNDANCY – SPANNING TREE

The Spanning-Tree Protocol is a standard protocol that is defined in IEEE 802.1D. It is used to build
a logical loop-free topology for layer-2 Networks. The basic function of the protocol is to prevent loops
and broadcast flooding around the switches. STP allows spare links in the network design to
provide backup paths when the active link fails and requires a convergence time of 30-50 seconds to
recover the topology when the topology is changed. This prompted the use of Rapid Spanning-Tree
Protocol as it provides a faster convergence when the topology is changed.
RSTP was introduced by IEEE as 802.1w. It can respond within 3 x "Hello Time" when a topology is
changed. The "Hello Time" is a configurable value and it is very important for RSTP. The default RSTP
value is 2 seconds and typically, the convergence time for RSTP is under 6 seconds. RSTP is much faster
than STP. RSTP should be used instead of STP.
The Multiple Spanning-Tree Protocol defined in the IEEE 802.1s is an extension to RSTP for Virtual LANs.
MSTP provides a better alternate path than STP/RSTP for different VLANs. It can make a group of VLANs
more systemized in the topology.

RSTP: Enable STP and run "RSTP" for redundancy. MSTP: Enable STP and run "MSTP" for redundancy. Disable: Disable STP. Users have to enable another protocol to prevent from loop.
Root Priority
•
It is used to define the "Root Bridge". The bridge with the lowest Root Priority is the "Root Bridge". If all the bridges are set to the same Root Priority value, the system will select the Root Bridge based on the MAC Addresses. The range of Root Priority is from 0 to 61440(multiple of 4096). The default Root Priority is 32768.
Hello Time
•
It is very important and used to determine the interval to send BPDU (management frame) to check the RSTP topology and status. The range of Hello Time is from 1 to 10 second(s). The default Hello Time is 2 seconds.
Forward Delay
•
A delay/timer is used to determine when to change the Path State from Learning/Listening to Forwarding. The range of Forward Delay is from 4 to 30 seconds. The default Forward Delay is 15 seconds.
