Enhanced Flexibility – Extends the System Freely

Improved Maintainability –

Keeps the System Running

System Extension Structure

The length of extension cables between each AH500 local extension rack can reach a maximum of 100m, greatly

enhancing wiring exibility. In addition, the AH500 provides modularized backplanes and modules applicable for

not only CPU racks but also for remote I/O racks. This feature improves the exibility of system planning and

reduces the additional cost that might be generated by preparing two different types of spare backplanes and

modules.

The hot-swap function provided for AIO and DIO modules increases maintainability when I/O modules fail.

Users can replace modules without stopping the operation of the CPU module, preventing a possible loss

due to a pause in the system's operation.
