6.7 PoE

Note: The PoE function and the following screens are available for models ending in “HP”

only.

The Switch supports both the IEEE 802.3af Power over Ethernet (PoE) and IEEE 802.3at High Power

over Ethernet (PoE) standards. The Switch is Power Sourcing Equipment (PSE) because it provides

a source of power via its Ethernet ports, and each device that receives power through an Ethernet

port is a Powered Device (PD).

In the figure below, the IP camera and IP phone get their power directly from the Switch. Aside

from minimizing the need for cables and wires, PoE removes the hassle of trying to find a nearby

electric outlet to power up devices.

Figure 26 Powered Device Examples

You can also set priorities so that the Switch is able to reserve and allocate power to certain PDs.

BPDU Control Configure the way to treat BPDUs received on this port. You must activate bridging control

protocol transparency in the Switch Setup screen first.

Select Peer to process any BPDU (Bridge Protocol Data Units) received on this port.

Select Tunnel to forward BPDUs received on this port.

Select Discard to drop any BPDU received on this port.

Select Network to process a BPDU with no VLAN tag and forward a tagged BPDU.

Media Type On the Switch that has a 10 Gigabit interface, such as the SFP+ slot, you can insert either

an SFP+ transceiver or an SFP+ Direct Attach Copper (DAC). An SFP+ Direct Attach Copper

(DAC) is an SFP+ housing that has no optical module but uses a fixed-length passive copper

cable assembly, which reduces cost and power significantly.

Select the media type (sfp_plus or dac10g) of the SFP+ module that is attached to the 10

Gigabit interface.

Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these

changes if it is turned off or loses power, so use the Save link on the top navigation panel to

save your changes to the non-volatile memory when you are done configuring.

Cancel Click Cancel to begin configuring this screen afresh.
