Black Box Pro Switching System Plus SNMP/RS-232/Manual Switching - expansion module

Switch one card, the entire gang switch or an entire daisy chained system using Ethernet. The Controller Card is the key to the Pro Switching System Plus. 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 RS-232 connection.
