Triple Speed Functionality and Switching
The Moxa EtherDevice Switch’s 10/100/1000 Mbps switched RJ45 port
auto negotiates with the connected device for the fastest data
transmission rate supported by both devices. All models of Moxa
EtherDevice Switch are plug-and-play devices, so that software
configuration is not required at installation, or during maintenance. The
half/full duplex mode for the switched RJ45 ports is user dependent and
changes (by auto-negotiation) to full or half duplex, depending on which
transmission speed is supported by the attached device.
Jumbo Frame
The EDS-G205A-4PoE series supports Ethernet jumbo frames up to 10k,
which is with more than 1500 bytes of payload. This function is by default
disabled and can be enabled by turning on the DIP switch labeled “Jumbo”
on the top cover. This is commonly used for large packet size applications
such as video surveillance.
Broadcast Storm Protection
The EDS-G205A-4PoE Series has a built-in algorithm for limiting the
amount of broadcast packets through the switch. This function is by
default disabled and can be enabled by turning on the DIP switch labeled
“BSP” on the top cover. If the broadcast storm protection algorithm
detects more than 2k broadcast frames per second, then the switch will
be suppressed from receiving broadcast frames for a period of 2 ms to
prevent any further flooding.
Total Power Budget
For the total power budget, the EDS-G205A-4PoE will provide 62 W at 12
to 17 VDC input, 120 W at 18 to 35 VDC input, and 144 W at 36 to 57 VDC
input. The total power budget is the total amount of reserved PoE power
based on the PoE class of the PoE device. If a newly connected PoE device
causes the total reserved power to exceed the total power budget, the
newly connected PoE device will be denied power.
