AT-FS232 and AT-FS232/x Series Installation Guide

Note

MissingLink and Smart MissingLink are disabled when you perform a

link test. Consequently, to ensure that MissingLink or Smart

MissingLink is enabled on the bridging converter, always set the Mode

Selection button so that the ML or SML LED is green during normal

network operations.

Smart MissingLink

The Smart MissingLink feature performs exactly the same function as

MissingLink with one additional feature. When a link is lost on a port, the

LNK LED of the port which still has a valid connection to its end-node starts

to blink. This allows you to quickly determine which port still has a valid

connection (LNK LED blinking) and which port has lost its connection (LNK

LED off).

For example, if the network twisted pair cable to the 10Base-T/100Base-TX

port on the bridging converter were to fail, the LNK LED on the 100Base-FX

fiber optic port will blink, indicating a failed connection on the twisted pair

port. If the failure had started with the fiber optic cabling, the LNK LED on

the twisted pair port would blink.

The value to this type of network monitoring and fault notification is so that

you can quickly see which port has failed and troubleshoot your network

accordingly.

Bridging Converter Performance

The bridging converters perform at:

❑ 148,800 pps for 100 Mbps and 14,880 pps for 10 Mbps for full wire

speed forwarding and filtering

❑ 200 Mbps maximum throughput in 100 Mbps, full-duplex mode

❑ 20 Mbps maximum throughput in 10 Mbps, full-duplex mode

❑ Storage for up to 4,000 MAC addresses

❑ 280 KB (per port) packet buffer

❑ Low latency 14.3 µs (64-byte packet, 100 Mbps full-duplex)
