1Introduction
Overview
The Switch is a high performance multi-mode PoE switch. Provides twenty-four 10/100 Mbps Auto-
Negotiation RJ-45 ports, plus one gigabit Combo ports, it can be used to link bandwidth higher
upstream equipment. These PoE ports can automatically detect and supply power with those IEEE
802.3at compliant Powered Devices (PD) such as AP, IP Cameras or IP Phones, etc. The switch port1 and
port2 can support the 802.3bt standard, and the maximum output power can reach 60W.The switch
on the panel to stir, can be configured to automatically switch the normal working mode, port isolation
(VLAN) mode, monitoring mode, network extend mode, flexible and extensible family, office network
without power line layout restrictions; meet the small and medium-sized enterprises, intelligent
community, hotels, parks and office network network networking and access requirements.
Product Features

Mode Control:
You can select the switch mode.
Normal mode (NORMAL): Switch all ports can communicate with each other
Port isolation mode (VLAN): 1 to 24 cannot communicate with each other, but can communicate with
the uplink Combo port 17.

Monitoring mode (MONITOR): 1 to 8 ports support port priority, optimize port cache, switch all ports
can communicate with each other.
Network extend mode(EXTEND): 1 to 8 port rate down to 10 Mbps, the farthest transmission distance
of up to 250 meters, all ports can communicate with each other.
10/100 Mbps RJ-45 ports (1 to 24):
Designed to connect to the device with a bandwidth of 10 Mbps, 100 Mbps. Each has a corresponding
Link/Act and PoE indicator.
10/100/1000Mbps RJ-45 port 25:
Designed to connect to the device with a bandwidth of 10 Mbps, 100 Mbps or 1000 Mbps. Each has a
corresponding Link/Act LED.
1000Mbps SFP port 25:
Designed to install the SFP module. The Switch features one SFP transceiver slots that are shared with
one associated RJ-45 ports. A SFP port and an associated RJ-45 port are referred to as "Combo" port,
which means they cannot be used simultaneously, and only SFP port work or only RJ-45 port work at
the same time.
1.3.2 Rear Panel
The rear panel of the Switch contains one Grounding Terminal, Heat vent and AC power connector
shown as below.
Rear panel
Grounding Terminal:
Located on the left side of the power supply connector, use wire grounding to lightning protection.
Heat vent:
The Heat vent is located in the middle position of the rear panel of the switch. It is used for heat
dissipation and ventilation. Do not cover it.
AC Power Connector
:
Power is supplied through an external AC power adapter. It supports 100–240 VAC, 50/60 Hz.
Package Contents
Before installing the Switch, make sure that the following the "packing list" listed OK. If any part is lost
and damaged, please contact your local agent immediately. In addition, make sure that you have the
tools install switches and cables by your hands.
