Product Features

  • Ethernet port for SNMP, telnet, or web browser remote access for individual card switching, Rack switching, and System Gang Switching
  • Supports individual card switching, Rack switching, and System Gang Switching using the front panel push-button switches
  • Supports Gang Switching using an external +12 VDC signal or external remote contact switches.
  • A key lock switch on the rack allows the user to enable or disable manual switching
  • Supports RS-232 communications on the Gang-In and Gang-Out connectors.
  • Allows racks to be addressed, and individual Switch Cards within the rack to be switched with serial commands
  • There can only be one SNMP style Controller Card in a daisy chained system of racks.


  • If you plan to daisy-chain multiple chassis, the Controller Card in the first chassis controls the entire system.

The advanced design of the Pro Switching System, 2U (SM260A) gives incredible operational flexibility and performance. Switch one card individually or switch the entire chassis through a Controller Card. You'll need one Controller Card per rack chassis. If you plan to daisy-chain multiple chassis, the Controller Card in the first chassis controls the entire system.

This card enables you to switch the chassis from anywhere via an RS-232 or IP connection.

We also offer an RS-232 Only Controller Card (SM263A), which enables you to gang switch via the manual toggle switch or with serial commands.

Or if you want to extend RS-232/IP control to a second daisy-chained Pro Switching System chassis, order the SNMP Expansion Controller Card (SM264A). This enables you to send hardware control signals and control the daisy-chained system with RS-232 messages through the RS-232/Ethernet (SNMP) Controller Card (SM262A).
