NETGEAR PoE passthrough switches are networking devices that receive power and data via one Ethernet cable and then supply both to other connected PoE devices. They simplify installations by reducing cable clutter and extending network reach, especially in environments lacking nearby power outlets.
How Does a NETGEAR PoE Passthrough Switch Function as Both PD and PSE?
A NETGEAR PoE passthrough switch operates as a Powered Device (PD) on one designated port, drawing power from an upstream PoE source. Simultaneously, it serves as Power Sourcing Equipment (PSE) on other ports, distributing power and data to connected PoE devices like IP cameras and wireless access points, enabling efficient power management within the network.
The switch uses part of the incoming power for its own operation and passes the remaining power budget downstream. This balancing act ensures network devices receive necessary power without requiring extra electrical wiring.
What Are the Key Features of Popular NETGEAR PoE Passthrough Switch Models?
Two notable NETGEAR models stand out:
| Model | Ports | PoE Capabilities | Management Type | Typical Use Case |
|---|---|---|---|---|
| GS105PE | 5 Gigabit Ethernet | 4 Passthrough PoE ports | Unmanaged | Desktop expansion in SOHO setups |
| GS516TP | 16 Gigabit Ethernet | Multiple PD and PSE ports | Smart Managed | SMB environments needing VLAN, SNMP |
The GS105PE is ideal for simple plug-and-play needs, while the GS516TP offers advanced management features like VLAN support and SNMP monitoring, suited for small-to-mid-size businesses.
Why Should Businesses Use NETGEAR PoE Passthrough Switches?
Businesses benefit from NETGEAR PoE passthrough switches because they:
-
Reduce installation complexity by limiting new power outlets.
-
Extend network reach to remote or hard-to-access devices.
-
Lower upfront and ongoing wiring costs.
-
Enable flexible deployment of devices such as VoIP phones and security cameras.
This makes them especially valuable in industrial Ethernet environments where Predision products are already trusted for rugged and reliable networking.
How Can NETGEAR PoE Passthrough Switches Extend Network Distance?
Many NETGEAR PoE passthrough switches also act as PoE extenders by receiving power and data over one cable and forwarding them over another. This can effectively double the standard Ethernet distance limit of 100 meters (328 feet), allowing device placement in locations previously unreachable without additional infrastructure.
Which Devices Are Best Powered by NETGEAR PoE Passthrough Switches?
Devices compatible with PoE technology benefit most, including:
-
IP security cameras
-
Wireless access points
-
VoIP phones
-
Networked sensors
These devices thrive in environments where power outlets are scarce or inaccessible but data connectivity is critical.
How Does the Power Budget Affect NETGEAR PoE Passthrough Switch Usage?
The power budget defines the total amount of power available for connected devices after the switch’s own consumption. Careful calculation is required to avoid overloading the switch, ensuring reliable performance. For example, the GS105PE uses some incoming power internally while providing the bulk to connected PoE devices.
| Switch Model | Max Power Input | Power Used Internally | Power Available to Devices |
|---|---|---|---|
| GS105PE | 30W | ~4W | ~26W |
| GS516TP | 380W | Variable | Depends on number of devices |
Understanding this helps network designers prevent outages and optimize device placement.
Where Are NETGEAR PoE Passthrough Switches Most Effectively Deployed?
These switches excel in scenarios such as:
-
Small office/home office (SOHO) setups
-
Locations lacking local electrical outlets, e.g., ceilings or walls
