PoE Overview

Power over Ethernet (PoE) means that power sourcing equipment (PSE) supplies power to powered devices (PD) such as IP telephone, wireless LAN access point, and web camera from Ethernet interfaces through twisted pair cables.

Networking and Configuration Requirements

The switch supplies power to a PD through a PoE interface.

l          GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 are connected to IP telephones.

l          GigabitEthernet 1/0/11 and GigabitEthernet 1/0/12 are connected to access point (AP) devices.

l          The power priority of GigabitEthernet 1/0/2 is critical. No power will be supplied to a new PD if the PSE power is overloaded, that is, the default policy of PD power management is adopted.

l          The power of the AP device connected to GigabitEthernet 1/0/11 does not exceed 9,000 milliwatts.

Networking and Configuration Requirements

The switch supplies power to a PD through a PoE interface.

l          The device is equipped with two PoE-supporting cards, which are inserted in Slot 3 and Slot 5 respectively. The PSE IDs are 10 and 16.

l          Allocate 400 watts to PSE 10, provided the default maximum power to PSE 16 can meet the requirements.

l          GigabitEthernet 3/0/1 and GigabitEthernet 3/0/2 are connected to IP telephones.

l          GigabitEthernet 5/0/1 and GigabitEthernet 5/0/2 are connected to access point (AP) devices.

l          The power priority of GigabitEthernet 3/0/2 is critical. No power will be supplied to the new PD if the PSE power is overloaded, that is, the default policy of PD power management is adopted.

l          The power of the AP device connected to GigabitEthernet 5/0/1 does not exceed 9,000 milliwatts.

Configuration Guidelines

To provide PoE supply to attached devices, the S7500E series require appropriate PoE power modules. PoE power modules fall into external and internal types.

1)        The S7502E requires both internal power modules for its own power feed and an appropriate external PoE power module, PSE2500-A3 for example, to provide PoE supply.

2)        The S7503E, S7506E, S7506E-V, and S7510E require only internal PoE power modules, PSR1400-D for example, for both their own power feed and PoE supply to attached devices.

For the details, refer to H3C S7500E Series Ethernet Switches  Installation Manual.
