A G450 gateway will draw a maximum of 133W fully loaded.

Default G450 Power Specifications

I need to get data on the following for the G450 with Dual Redundant Power Supplies (400W each):

1. Max Input VA (or Watts & Power Factor)
2. Max Output VA (or Watts & Power Factor)
3. Max BTU's Dissipated
4. The application will be 208 VAC (Nominal)

The power supplies are rated for 400 Watts, but this is typically what the output of the power supply is. I need to know the maximum input power that will be required for the power supplies in the configuration identified above. Additionally, it would be very helpful to get a reference for an Avaya document that contains this information so it can be included in our files.

We have purchased around $1MM dollars worth of equipment for our site wide phone switch upgrade (from Nortel SL-100), but the IT folks don't have the technical information for the electrical installation. The information you supply will help to provide this.

I can be called at 361-972-8639 if necessary. Thanks in advance for your assistance in this matter.

Hello. Found this old topic. I have the same task. There will be four G450 fully equiped with MM716 modules. I also saw in documentation for G450 Power rating - 522 W Max Current - 7A. I need to calculate the amount and characteristics of batteries. They must supply one hour working for these gateways. As far as I understood, power rating of 522 W is the power that can be delivered by the source to it`s output (to gateway modules). How to calculate the maximum power that PSU can consume from AC or from batteries.
