PoE Power over Ethernet

Chapter 1 Configuration

1.1 Introduction

With the advent and rapid spread of IP telephony based on Ethernet Interfaces, a mechanism to supply power to net-
work devices over existing infrastructures has become necessary. At the same time, devices that are able to provide
backup mechanisms and centrally manage the power supplied to these network devices are also needed.

Thanks to the IEEE. 802.3af Power Over Ethernet (PoE) standard, up to 15.4 watts of DC power can be delivered
over the Ethernet copper cable. This allows for new network powered devices to be integrated on existing LAN infra-
structures, without having to resort to more cabling or power supplies.

In addition, the IEEE PoE standard allows power sourcing equipment (PSE) and the powered device (PD) to signal
one another. This way, the power source can identify the device and determine the amount of power required (thus
enabling efficient management of the power provided).

We have developed some modules that are capable of providing PSE functionality to certain devices with switch
functionality. They all share the configuration and monitoring described in this manual.

1.2 Installation

The external power source of routers with this functionality must be connected to the PSE connector before the
device is switched on.

Each Switch port has two LEDs. One of them is yellow and indicates the status of the port at the delivered power
level:

1.3 Configuration Commands

This chapter describes the power sourcing equipment (PSE) configuration commands and is divided into the follow-
ing sections:

• Viewing the PSE configuration prompt.

• PSE configuration commands.

1.4 Viewing the PSE configuration prompt

To access the configuration environment, do the following:

(1)

At the GESTCON (*) prompt, enter PROCESS 4 (or P 4) or CONFIG.

(2)

At the configuration prompt (Config>), enter NETWORK <interface_name> (interface_name is the name of
the Ethernet interface on which the PSE functionality can be used).

(3)

To set specific POE parameters, use the available commands from the PSE configuration menu described in
this chapter. To access the menu corresponding to the specific parameters, enter the POWER-
SOURCING-EQUIPMENT command once inside the interface configuration.

used after a specific command to list the available options.

1.5.2 AVAILABLE-POWER

This command allows you to set a deliverable power limit for all devices powered by the switch. Default is 120000.

The indicated value is in milliwatts.

Use the NO command to restore the default value.

For the equipment to function correctly, the value configured in this parameter must always be equal to (or lower
than) the actual value of the source connected to the router.

Syntax:

ethernet0/0 PSE config>available-power ?

<120000..245000>

milliWatts

Example:

ethernet0/0 PSE config>available-power 140000

1.5.3 DEFAULT-PORT-CONSUMPTION

Allows you to set the computed consumption value for each device connected to the switch.

The value is 0 by default, corresponding to the NO value.

The indicated value is in milliwatts.

The following strategy is used when calculating the power delivered to the devices:

• If a value has been configured for this parameter, it will be used as the consumption value for each connected

device.

By programming this parameter, you do not need to be overly restrictive with the devices that show high consump-
tion levels during detection (automatically assigned to the default class when incapable of implementing class detec-
tion) but end up not consuming as much.

Note

Programmers are responsible for assigning values that match the actual parameters of the devices to
be connected.

• If a value has not been configured, the consumption value for each device will correspond to the value configured

for the port (when in forced power mode) or to the value of the class detected for this device. In this case, the
power is:

Power delivered by default: 15400 mW.
Default class for devices that do not implement detection.

“Low Power PD” devices

Power delivered by default: 4000 mW.
