Black Box Pro Switching System Multi Switch Card, CAT5e, Dual 2-to-1 - expa

The Controller Card is the key to the Pro Switching System Multi. One is required for each 18-slot chassis, and it takes up two card slots. The Controller Card enables you to individually switch any port from the front panel, or gang switch the entire system. With the intelligent card, you can also switch using SNMP or an RJ-45 or CAT5e connection.
