Product overview

The Netgear M4250-40G8XF-PoE+ AV Line Managed Switch, SKU GSM4248PX-100NAS, is a 48 port managed Ethernet switch designed for environments that need a mix of powered and fiber connected devices. Classified under 48 port managed switches, it integrates 40 PoE+ ports and 8 SFP+ ports to support both copper and fiber connectivity in one platform. The 40 PoE+ ports allow consolidated power delivery to compatible endpoints, while the 8 SFP+ interfaces provide flexible uplink or aggregation options using fiber transceivers. As a managed switch, it enables more controlled network configurations compared with unmanaged alternatives, aligning with structured deployments in professional networks. Positioned in the AV Line, this model can align with audio or video over IP workflows that require a combination of high port density, power delivery, and fiber uplinks within a single rack mountable switch chassis.

Best for

AV over IP
Suitable for AV over IP deployments that need many powered endpoints, using 40 PoE+ ports for devices such as AV encoders, decoders, or displays while reserving 8 SFP+ ports for fiber uplinks to core switching.
Enterprise edge
Fits enterprise edge closets where multiple PoE+ powered devices are required, leveraging 40 PoE+ ports for access devices and 8 SFP+ ports to connect upstream distribution or core switches over fiber.
Campus networks
Supports campus building aggregation where PoE+ powered endpoints connect over the 40 PoE+ ports and the 8 SFP+ ports serve as high speed fiber uplinks between buildings or floors.
Mixed copper and fiber access
Ideal where a single managed switch must provide PoE+ copper access and fiber connectivity, combining 40 PoE+ ports with 8 SFP+ ports to simplify rack layouts and cabling.
High density PoE deployments
Useful in high density PoE deployments that require many powered endpoints on one switch, taking advantage of 40 PoE+ ports while still maintaining 8 SFP+ ports for uplink or aggregation.

Frequently asked questions

How many devices can this switch connect and power directly?

This switch is a 48 port managed Ethernet model with 40 PoE+ ports. It can connect up to 48 devices in total, and up to 40 of those can be powered directly via PoE+ if they support it. The remaining ports include 8 SFP+ interfaces, which are typically used for uplinks or fiber connected devices rather than PoE powered endpoints.

What types of uplinks are supported on the GSM4248PX-100NAS?

The GSM4248PX-100NAS includes 8 SFP+ ports in addition to 40 PoE+ ports. These 8 SFP+ ports are intended for fiber based uplinks or aggregation links when equipped with compatible SFP+ transceivers. This allows you to connect the switch to distribution or core switches over fiber while using the PoE+ ports for access devices.

Is the GSM4248PX-100NAS suitable for managed network deployments?

Yes, the GSM4248PX-100NAS is categorized as a managed Ethernet switch. As a managed device, it is designed to participate in environments where configuration and monitoring are required, such as segmented enterprise or AV networks. Its 48 port design, combining 40 PoE+ ports and 8 SFP+ ports, aligns with structured managed network deployments.

How does the port mix support AV over IP or similar applications?

The switch offers 40 PoE+ ports and 8 SFP+ ports within a 48 port managed platform. In AV over IP scenarios, the 40 PoE+ ports can connect and power AV encoders, decoders, or control devices, while the 8 SFP+ ports can be used as fiber uplinks to central switching. This port mix supports both high density endpoints and backbone connectivity.

What product identifier should be used for procurement of this switch?

For procurement purposes, the switch is identified by SKU GSM4248PX-100NAS and is described as the Netgear M4250-40G8XF-PoE+ AV Line Managed Switch. Using this exact identifier helps ensure purchasing teams order the correct 48 port managed switch with 40 PoE+ ports and 8 SFP+ ports specified in project documentation.
