Product Features

  • Add reliability to critical networks and systems with a compact 2U Gang Switch system.
  • Monitor and control access to networks remotely
  • Gang switch all ports or switch individual ports
  • Automate the backup of individual connections or entire networks based on port failure or time of day.
  • Daisy-chained system of racks is limited to 255 switch cards


The Pro Switching System 2U is an intelligent ganged switching system consisting of an ultra-compact 2U 18-slot chassis and a selection of A/B switching, controller, and power supply cards.

Controller Cards take up only one slot, and Power Cards take up one slot or two slots for redundancy, leaving you with 13 - 15 slots for A/B Switch Cards. All occupy one slot, except for the DB25 Cards, which require three slots.

Local and remote control
The advanced design of this system gives incredible operational flexibility and performance. Switch one card individually or switch the entire chassis through a Controller Card. You will 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.

You can choose an RS-232 Only Controller Card, which enables you to gang switch via the manual toggle switch or with serial commands, as well as an RS-232/Ethernet (SNMP) Controller Card, which enables you to switch the chassis from anywhere via an RS-232 or IP connection.

If you want to extend RS-232/IP control to a second daisy-chained Pro Switching System chassis, order the SNMP Expansion Controller Card. 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.

Secure and fallback switching.
For fail-safe operation, all the cards (except those noted) use proprietary latching or micro-mirror relay switching technology - which means data can continue to pass through even if the power has been cut off. Because the cards perform Layer 1 switching, the system operates independently of data rates, protocols, formats, or signal levels.

The non-latching fiber cards fall back to a Port C (chassis) to Port A connection when the power fails. When power is restored, the non-latching switch card reconnects Port C to the originally selected port (A or B). These types of cards are typical when you want a fallback or failover connection during power outages.

Each chassis also has a keyed switch so you can enable/disable manual switching from the front-panel toggle switches.

Control power.
To power your chassis, order one or two external power supplies, and the power adapter card. For backup power, add a Redundant Power Supply Card.
