Chapter 1 PoE Configuration

1.1 PoE Overview

1.1.1 PoE on the Switch

H3C S9500 Series Routing Switches (hereinafter referred to as S9500 series) support

power-over-Ethernet (PoE). Equipped with external power supply and PoE-capable

cards, S9500 series can provide 48 VDC power for remote powered devices (PDs,

such as IP phones, WLANAPs, and Network cameras) through twisted pairs.

zThe S9500 series support LEGACY Power Supply standard. While they can also

supply power to PDs noncompliant with the standard.

The power supply of the S9500 series is administered by the SRPcard; each PoE card

on the switch can be viewed as a power sourcing equipment (PSE), which administers

the power supplying of all the ports on it independently.

The S9500 series can transmit data and supply power in the mean time through the

signal lines (1, 3, 2, and 6) of the category-3/5 twisted pairs. Using converters, they can

also supply power to the PDs that can be powered only through spare lines (4, 5, 7, and

8).

zThe S9500 series supply power through the Ethernet electrical ports on the

service cards. Each service card can supply power to up to 48 remote devices at

the maximum distance of 100 m (328 feet).

zThe maximum power that can be supplied by each Ethernet port to its PD is 16.8

zWhen supplying power to remote devices, the maximum total power that can be

provided by the S9500 series is 4500 W (220 V)/2250 W (110V). The switch

determines whether or not to supply power to the next remote PD it discovered

depending on the total power it currently supply.

Note:

zWhen a remote PD is powered by an S9500 series switch, the PD needs not have

any external power supply.

zIf the remote PD has an external power supply, the S9500 series switch and the

external power supply will be redundant with each other for the PD.

1.1.2 External PSE4500-A Power System

If PSE4500-A power system is taken as the external power supply of the switch, the

power distribution is as follows:

1) Input voltage: 110 VAC

zOne or two PSUs (power supply unit) of the PSE4500-Apower system can provide

1200 W of power.

zIf the PSE4500-A power modules work in 2+1 redundancy backup mode, then

each module provides 750 W of power.

2) Input voltage: 220 VAC

zOne or two PSUs of the PSE4500-Apower system can provide 2500 W of power.

zIf the PSE4500-A power modules are in 2+1 redundancy, then each module

provides a power of 1500 W.

1.1.3 PoE-Capable Card

The following service card of the S9500 series supports PoE:

zGV48D

1.2 PoE Configuration

The S9500 series can automatically detect any connected device that needs remote

power supply and feeds power to this device.

zDepending on your actual network requirement, you can set the maximum PoE

power totally supplied by the switch through the command line.

zYou can set the maximum PoE power supplied by a card through the command

line.

zYou can also control the PoE on each PoE port independently through the

command line. The control includes: enabling/disabling the PoE feature, and

setting the maximum PoE power, the PoE mode and the PoE priority on the port.

Note:

zBefore setting the maximum power supplied by a card, make sure the remaining

power of the switch is no less than the full power of the card, and the power you can

set for a card ranges from 37 W to 806 W.

zThe reserved power for a blank slot will be recycled automatically by the system if

you insert a PoE-incapable card into the slot.

zWhen a card is almost fully loaded and a new PD is added, the switch willrespond to

the PD according to the PoE priority set on the port.

zThe PoE priority of each port is based on its card. In other words, the switch cannot

compare the priorities of ports on different cards.

zThe sampling cycle of the power, current and voltage of ports is 1 second; the

sampling cycle of the peak power and average power of both cards and ports is 5

minutes

1.3 Comprehensive Configuration Example

I. Network requirements

zTwo PoE-capable cards are installed in slots 3 and 5 on an S9500 series routing

switch.

zGigabitEthernet3/1/1 through GigabitEthernet3/1/48 are connected with IP

phones and GigabitEthernet5/1/1 through GigabitEthernet5/1/48 are connected

with access point (AP) devices.

zThe IP phones connected to GigabitEthernet3/1/23 and GigabitEthernet3/1/24 do

not need PoE.

zGigabitEthernet3/1/48 is reserved for the use of network management, so it needs

higher priority.

zSlot 3 is provided with 400 W power and slot 5 is provided with full power.

zThe input power of the AP device connected to GigabitEhternet5/1/15 cannot be

greater than 9000 mW.
