NOTE:
1. This product is a PoE Passthrough Switch, designed to operate by connecting its PoE IN port to a PoE-enabled switch or PoE injector. When connected, it works without the need for an external power adapter.
2. Since most users power this device via PoE, no power adapter is included in the package.
If you plan to use the DC input and require PoE output on LAN1-4 ports, please use a compatible DC 48V-57V power adapter with the following specifications:
DC port: 5.5mmx2.1mm
DC Input Polarity: Positive inside (+), Negative outside (-).

Features
The PoE Extender/Switch requires no local power supply and is powered by the uplink port PoE input.
It also supports DC power input: DC 12V-57V, 5.5x2.1 mm DC ports*.
Supports PoE++ (802.3bt) power input with a maximum input power of 90 watts and a total output power of 72 watts for LAN1-LAN4 PoE.
LAN1-LAN4 supports PoE+ (802.3at) output.
LAN1-LAN4 Extended Mode: Maximum cable length is up to 250 meters, Ethernet speed: 10 Mbps**
LAN1-LAN4 LAN mode: Maximum cable length up to 100 meters, Ethernet speed: 1000 Mbps
Automatically detects and protects PoE devices from damage.

Supports IEEE 802.3af/802.3at/802.3bt (up to 90 watts) Power over Ethernet (PoE) switches
Supports DC 48V-57V passive Power over Ethernet PoE switches
Supports DC 48V-57V passive Power over Ethernet PoE injectors

The PoE Extender/Switch has five 10/100/1000 Mbps PoE ports, with the Uplink port for PoE input (IEEE 802.3bt/802.3at/802.3af compliant) and LAN1-LAN4 ports for PoE output (IEEE 802.3at/802.3af compliant). All ports are 10/100/1000BASE-TX compliant.
The PoE Extender extends the transmission distance to 100-250 meters over Cat5E/6E UTP cables. This provides great flexibility in extending PoE distances.**

*When the DC interface input voltage is lower than DC 40V, PoE output on LAN1-LAN4 is disabled. If PoE functionality is required, it is recommended to use a DC 48V-57V power supply.
**Ext mode Note:
1. When Ext mode is enabled, the maximum bandwidth for LAN1-LAN4 network ports is reduced to 10 Mbps per port. Please check your IP camera's bit rate settings. We recommend that the bit rate does not exceed 8 Mbps (8192 Kbps).
2. When Ext mode is enabled, Isolates LAN ports from each other while maintaining uplink access, reducing broadcast storms and improving network stability.
