Frequently asked questions
Will the QJ71C24-R2 drop into a panel specified for the LJ71C24-R2 without rewiring?
No. The QJ71C24-R2 is designed for the Mitsubishi Q-series backplane, while the LJ71C24-R2 is for the L-series. The form factor, bus interface, and mechanical mounting differ. A panel built for an L-series module cannot accept a Q-series module without changing the rack and power supply.
