# Quasar Power Supply Configuration

## Scope

This document applies the Power Supply configuration for the Quasar console frames only.

## Description

Quasar power supply modules (PSU) have a built-in load-sharing mechanism. This means that every PSU module constantly contributes power to the surface. No switching ever takes place if one should fail. This ends up being a much smarter way to handle redundancy.

Quasar can be configured with **UP TO** four power supply units per frame, depending on the frame size and the user requirements in terms of power redundancy.

> [!WARNING]
> The console frames always come standard with a **non-redundant** PSU configuration.

The following table describes the number of supplies as standard and the number of optional supplies.

|  | **Frame Size** | **PSU Configuration** | **PSU Quantity** |
| --- | --- | --- | --- |
| **Standard** | from 2.5U to 5.5U | NON-redundant PSU operation | 1x PSU Module per frame |
| **Optional** | from 3.5U to 5.5U | Redundant PSU operation | 2x PSU Modules per frame |
| **Standard** | from 6.5U to 8.5U | NON-redundant PSU operation | 2x PSU Modules per frame |
| **Optional** | from 6.5U to 8.5U | PSU operation with single hot-spare | 3x PSU Modules per frame |
| **Optional** | from 6.5U to 8.5U | Fully redundant PSU operation (example, 2x PSU each to a separate AC mains supply. | 4x PSU Modules per frame |

> [!WARNING]
> NOTE - It is not possible to fit two PSUs in the 2.5U frame.
