Implementing PoE

The IEEE 802.3af standard, which is the IEEE standard for PoE, describes two

methods for implementing PoE over twisted pair cabling. One method uses the

same strands that carry the network traffic and the other the spare strands.

The PoE implementation on the AT-8624PoE switch transmits power over the

same strands that carry the network traffic (strands 1, 2, 3 and 6). The power

transfer does not interfere with the network traffic. The power and the network

traffic can coexist on the same strands simultaneously.

Powered devices that comply with the IEEE 802.3af standard support both

methods of power delivery. As long as a powered device is compliant with the

standard, it should be able to receive its power from the switch.

LEDs

The following tables outline how the switch and expansion modules report

faults and operational activities. Expansion modules are optional and can be

purchased separately. Contact an authorised Allied Telesis distributor or

reseller, or visit www.alliedtelesis.com for more information on expansion

modules.

System LEDs

Use the Mode Select button to toggle the Mode LEDs to the desired state.

Toggling the Mode Selection button does not affect the normal switch

operations.

LED State Description

FAULT Off Switch operation is normal.

Red The switch or management software is malfunctioning.

1 flash A switch fan has failed.

3 flashes The main PSU has failed and the RPS is now providing

power.

4 flashes The RPS Monitor is set to ON, and the RPS is not

functioning, either because it has failed or has been

switched off.

5 flashes The RPS Monitor is set to ON, but the RPS is not

connected.

7 flashes For the AT-8624T/2M and AT-8624PoE switches: An

expansion module has been inserted or removed while

the switch is powered on.

MASTER Off This LED is not supported.

RPS Green An optional redundant power supply is connected to the

switch.

OFF There is no optional redundant power supply connected

to the switch.

PWR Green The switch is receiving power and the voltage is within

the acceptable range.

Off The switch is not receiving power.

Green The end node is a powered device and the port

is providing power to it.

Amber The port is experiencing a problem providing

PoE to the end node.

Flashing

Amber

The port is connected to a powered device but

providing power to it would exceed the

maximum PoE power budget of the switch.
