Avaya G450 R2 400W Gateway Power Supply

This unit provides 400W of AC power for Avaya G450 R2 gateway systems. It fits into dedicated slots on the gateway chassis and supports commercial AC as the primary input source. The part number 700507394 identifies this specific replacement module.

Dual-Range AC Input 100–240V

The power supply accepts nominal ranges of 100 to 120 VAC and 200 to 240 VAC, both at 50 or 60 Hz. This wide input range allows operation on standard mains voltages worldwide without manual switching. Both slot 0 and slot 15 have dedicated AC input connections on the gateway.

Slide-In Module With Backplane DC Backup

Installation is a simple slide-in action into the designated power supply bay on the G450 R2 chassis. A single -48VDC input on the G650 backplane distributes backup power through the backplane to each supply. No cable routing to individual units is required for DC redundancy. Buyers needing hot-swap capability or front-panel status LEDs should verify those features separately.
