Gigabit Ethernet Plus Switches If the QoS mode on the switch is port-based (the default setting), the Priority field displays on the page. If the QoS mode is 802.1P/DSCP, the Priority field does not display. For information about setting rate limits for incoming and outgoing traffic, setting the port priority (if the QoS mode on the switch is port-based), setting the port speed (by default, the speed is set automatically), enabling flow control, and changing the port name label, see Manage individual port settings on page 29 Power over Ethernet You can manage Power over Ethernet (PoE) on the switch by turning the uninterrupted PoE feature on or off, and perform power cycling to reset one or more PSE ports. You can also view port status, and manage PoE settings for each Ethernet port. PoE considerations for switches that support PoE+ or PoE A switch that supports Power over Ethernet (PoE) or PoE+ prioritizes the PoE power that it supplies in ascending port order (that is, from the lowest-numbered port to the highest-numbered port), up to its total power budget. If the power requirements for the attached powered devices (PDs) exceed the total power budget of the switch, the PD on the highest-numbered port is disabled to make sure that the PDs that are connected to the higher-priority, lower numbered ports are supported first. Just because a PD is listed as an 802.3af PoE or 802.3at PoE+ powered device does not necessarily mean that it requires the maximum power limit of the specification. Many PDs require less power, allowing all PoE+ ports to be active simultaneously. PoE+ overview The PoE+ ports on model GS316EP (port 1-15) and model GS316EPP (port 1-15) support PoE+ (IEEE 802.3at) and PoE (IEEE 802.3af), and can support non-PoE devices. The maximum PoE power budget on the switch depends on the model: • Model GS316EP: The maximum PoE power budget across all active PoE+ ports is 180W. The maximum PoE power that an individual PoE+ port can supply is 30W. • Model GS316EPP: The maximum PoE power budget across all active PoE+ ports is 231W. The maximum PoE power that an individual PoE+ port can supply is 30W. Maintain and Monitor the Switch 92 User Manual

Power over Ethernet
You can manage Power over Ethernet (PoE) on the switch by turning the uninterrupted
PoE feature on or off, and perform power cycling to reset one or more PSE ports. You
can also view port status, and manage PoE settings for each Ethernet port.
PoE considerations for switches that support PoE+ or PoE
A switch that supports Power over Ethernet (PoE) or PoE+ prioritizes the PoE power that
it supplies in ascending port order (that is, from the lowest-numbered port to the
highest-numbered port), up to its total power budget.
If the power requirements for the attached powered devices (PDs) exceed the total
power budget of the switch, the PD on the highest-numbered port is disabled to make
sure that the PDs that are connected to the higher-priority, lower numbered ports are
supported first.
Just because a PD is listed as an 802.3af PoE or 802.3at PoE+ powered device does
not necessarily mean that it requires the maximum power limit of the specification. Many
PDs require less power, allowing all PoE+ ports to be active simultaneously.
PoE+ overview
The PoE+ ports on model GS316EP (port 1–15) and model GS316EPP (port 1–15) support
PoE+ (IEEE 802.3at) and PoE (IEEE 802.3af), and can support non-PoE devices.
The maximum PoE power budget on the switch depends on the model:
•
Model GS316EP
: The maximum PoE power budget across all active PoE+ ports is
180W.
The maximum PoE power that an individual PoE+ port can supply is 30W.
•
Model GS316EPP
: The maximum PoE power budget across all active PoE+ ports
is 231W.
The maximum PoE power that an individual PoE+ port can supply is 30W.
