Poe; Poe Global Configuration - NETGEAR GS752TP Software Administration Manual

GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches

PoE

A Power over Ethernet (PoE) device is power sourcing equipment (PSE) that delivers
electrical power to connected powered devices (PDs) over existing copper cables without
interfering with the network traffic, updating the physical network, or modifying the network
infrastructure.
The switches support both IEEE802.3 at and af, as follows:
• GS728TP. Ports 1–8 support both IEEE802.3 at and af, and ports 9–24 support
IEEE802.3af. The maximum power budget is 192 Watts.
• GS728TPP. Ports 1–24 support both IEEE802.3 at and af. The maximum power budget is
384 Watts for AC mode and 720 Watts for DC mode or AC+DC mode when you are using
external power supply RPS4000.
• GS752TP. Ports 1–8 support both IEEE802.3 at and af, and ports 9–48 support
IEEE802.3af. The maximum power budget is 384 Watts.
The power limit of a port is set to the minimum between the class and the configured max
power limit.
You can configure per-port priority settings, timers, and power limits to manage the power
supplied to the connected powered devices (PDs) and to ensure that the power budget is
used effectively.
From the PoE menu under the System tab, you can view and configure PoE settings for the
switch.
PoE features are described in the following sections:
•

PoE Global Configuration

• PoE Port Configuration
• Timer Global Configuration
PoE Global Configuration
The PoE feature can be globally configured to generate the traps. If this feature is enabled,
the following traps are generated:
• Trap per port. Generated when the device begins or stops supplying power.
• Global. Generated when the device is using 95% of the threshold power.
