Netgear APS550W-100NES 100-240VAC Power Supply Unit (550W)

Product Overview

The NETGEAR APS550W-100NES is a 550W hot-swappable modular power supply unit built for the M4300 series PoE switch chassis. It installs into a free PSU bay on supported M4300 PoE models to add redundancy or expand the available power budget. Operating across a 100-240VAC input range, it suits North American and international AV rack deployments without configuration changes. The unit ships as a field-installable module for high-availability commercial AV and networking environments.

Product Description

This modular PSU is designed specifically as an additional or replacement power supply for the M4300-28G-PoE+ (GSM4328PA) and M4300-52G-PoE+ (GSM4352PA) switches. With a second unit installed, the switch gains 1+1 power redundancy so that a single supply failure does not interrupt connected AV-over-IP endpoints, PoE cameras, or access points. The same second supply can also raise the total PoE budget available to powered devices on supported chassis. The supply uses a standard C14 inlet and accepts 110V-240V AC input, delivering up to 575W output at 110/220V AC. As a hot-swappable module, it can be serviced without powering down the switch on chassis that support online PSU replacement. This makes it a practical spare to keep on hand for production AV racks where downtime is not acceptable.

Key Features

• 550W modular supply — Hot-swappable module rated up to 575W output at 110/220V AC for M4300 PoE switches.
• Wide AC input — Accepts 110V-240V AC through a standard C14 connector for domestic and international power.
• 1+1 redundancy — A second unit provides redundant power so a single PSU failure will not drop the switch.
• PoE budget expansion — Adding a supply increases the power available to PoE endpoints on supported chassis.
• Field serviceable — Hot-swap design allows replacement without taking the switch offline on chassis that support it.
• 5-year hardware warranty — Backed by a NETGEAR limited 5-year hardware warranty.

Typical Applications

• Redundant (1+1) power for M4300-28G-PoE+ and M4300-52G-PoE+ chassis switches
• PoE budget expansion on supported M4300 PoE switches feeding cameras, APs, and AV-over-IP endpoints
• Field PSU replacement or spares for high-availability AV racks

Frequently Asked Questions

Which switches accept the APS550W-100NES?
NETGEAR lists this PSU as an additional supply for the M4300-28G-PoE+ (GSM4328PA) and M4300-52G-PoE+ (GSM4352PA) PoE switches. Confirm your model before ordering.

Can I run two supplies for redundancy?
Yes. Installing a second supply provides 1+1 redundancy so the switch keeps running if one PSU fails, and can also expand the available PoE budget on supported chassis.

Is it hot-swappable?
It is a hot-swappable module and can be replaced without powering down the switch on chassis that support online PSU service.

What power input does it use?
It accepts 110V-240V AC through a standard C14 connector and delivers up to 575W output at 110/220V AC.

What warranty is included?
It is backed by a NETGEAR limited 5-year hardware warranty.
