Pro Switching System, 2U

The Pro Switching System 2U is an intelligent ganged switching system consisting if an ultra-compact 2U 18-slot chassis and a selection of A/B switching, controller and power supply cords.
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'll need one Controller Card per rack chassis. If you plan to daisychain 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 daisychained Pro Switching System chassis, order the SNMP Expansion Controller Card. This enables you to send hardware control signals and control the daisychained system with RS-232 messages through the RS-232/Ethernet (SNMP) Controller Card.
Pick a card, any card
A/B Switch Cards are available for RS-232, video, fibre optic, and CAT5e/CAT6 connections.Use the system for both new and legacy applications. You can add cards for fast CAT6 10-Gb E networking while keeping connections for older RS-232 and 75-ohm video connections.
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 fibre 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.
