Unmanaged operation
These switches require no supervisory processor to operate properly.
Flow control
These switches automatically support flow control frames on both the transmit and receive
sides.
Back-pressure flow control for half-duplex ports and pause-frame flow control for
full-duplex ports.
Forwarding
These switches support store and forward mode. They will forward messages with known
addresses out only the appropriate port. Messages with unknown addresses, broadcast
messages, and multicast messages will get forwarded out all ports except the source port.
Full / Half duplex operation
The RJ45 ports (except port 9, which is full duplex only) of these switches support both full
and half duplex flow control. The fiber optic port(s) has a settable jumper or switch, which
allows you to select the desired operation.
Illegal frames
Illegal frames as defined by IEEE 802.3 will be dropped. This includes short frames, long
frames, CRC error frames and alignment error frames.
IEEE 802.3 compliant
The Amphenol Industrial Ethernet Switch strictly abides to the IEEE 802.3 standard for
10BaseT, 100BaseTX, and 100BaseFX Ethernet communications.
Latency
The typical latency of a message at 100 Mbps is 5 microseconds or faster. The latency is
the time it takes a message to be routed internal to a switch from one port to another.
Non-blocking
This means that the switches offer the best in performance and are capability of full-wire
speed transmissions.
Plug and play
This means that most functions or features of these switches are automatic and that there
are minimal or no optional parameters that need to be set. Just plug in your Ethernet cables,
apply power, and the unit will immediately begin to operate.
Protocol independent
These switches will work with all popular Ethernet protocols and networks such as TCP/IP,
the Internet (IP), UDP, NetBEUI, and many more. It is compatible with all protocols that run
over standard Ethernet (IEEE 802.3). In fact, it will support packets of different protocols
simultaneously.
