3.2. Gigabit ethernet ports
– support PoE
Power over Ethernet (PoE) support means that the operating power is applied from a power source over
the LAN infrastructure, to power devices, which are connected to ports.
The R043 switch provides eight PoE ports which can be used to easily build a powered and centrally
controlled camera system, IP monitor system, or Internet-on-board system on vessels. Cameras or IP
sensors (e.g., temperature, humidity, leak, motion sensors can be easily installed for surveillance or
monitoring purposes. Without a power socket limitation, the R043 switch makes the installation of
surveillance and sensing equipment easier and more efficient.
All these RJ-45 type PoE ports are auto-negotiating. The ports can detect and adjust to the optimum
Ethernet speed (10/100/1000 Mbps) and duplex mode (full duplex or half duplex) of the connected
device.
3.3. Optical fibre SFP ports
The R043 features two optical fibre SFP slots, providing a high-speed and reliable connection option
between devices through fibre optic cables. They are a great option for networking due to no
electromagnetic interference, which can cause data transmission errors and affect network performance.
4. Status LEDs
The R043 features indicator LEDs which show power, system, Ethernet status. It helps monitor and
troubleshoot when needed.
