Summary of the features for PoE on TZ 300P and TZ 600P:

Features	TZ 600P	TZ 300P
External Power Supply Max	180 Watts	65 Watts
Max PoE Power Output Partition (Total for all PoE Port Power)	140 Watts	35 Watts
Number of PoE Ports	4 (X6 through X9)	2 (X3 and X4)
Number of Devices powered ON simultaneously	4 AF Devices or 4 AT Devices Max	2 AF Devices or 1 AT Device Max
Sequence of Devices powered ON	Based on Port Priority	Based on Port Priority
Front Panel PoE LED Colour	Blue - AT Device Connected Yellow - AF Device Connected Grey - No Device Connected	Blue - AT Device Connected Yellow - AF Device Connected Grey - No Device Connected

Features:

Ability to Detect, Classify, and Power ON/OFF, AF or AT devices.
Ability to change High and Low Power Mode.
Ability to Power ON based on Port Priority.
Ability to Administratively Enable / Disable PoE support on Ethernet Ports.
Ability to change Max Power Threshold for PoE PSE(Power Sourcing Equipment) ports - defaults is 100%.

Detection and Classification of PD (Powered Devices):

Automatically detects a PD device based on signature presented to PSE Appliance

Powers ON if PD Power Requirement is within Max Threshold Power value.
AT Device (Supports up to 30W at PSE)
AF Device (Supports up to 15.4W at PSE)

Power Modes:

Default Power Modes based on signature detection and classification:

AF Devices are powered ON in Low Power Mode always
AT Devices are powered ON in High Power Mode; they can be overridden by User configured Power Modes.

Two User Configurable Power Modes:

Low: AF Power (supplies up to 15.4 Watts)
High: AT Power (supplies up to 30 Watts)

Ability to change Power Mode:

Power Mode for AT devices can be changed to 802.3 AT (High) or 802.3 AF Low
Power mode for AF devices is always 802.3 AF (Low)

Mode changes are allowed:

Always, except it defaults to 802.3 AF (Low Power) when AF device is connected.
Power Mode can be changed even when no device is connected.
Configurations in Step 2 can be used for Provisioning other PoE Boxes.

NOTE: Though an AT device can be configured for Low Power Mode, at any point, if the device draws more than AF Power, Port Power will be cut off.

Priority based Port Powering:

Higher Port Number has Highest Priority in Powering ON
Ports with same Priorities, Highest Port Number has the Highest Priority
The priority of Ports can be changed from SonicOS UI

Enabling PoE:

Navigate to MANAGE | System Setup | Network | PoE Settings.
Click ENABLE POE. The Page expands. Click on the enable check-box, you can change the 'Max threshold Power' and then say OK.
The Network | PoE Settings page has two sections:
a) PoE Status: Provides graphical visualization by displaying:
Status indicator,
with the PoE interfaces (ports) designated by a circle icon and different colours.

These ports are also shown in PoE Monitor table.

Circle Color on Port symbol in PoE Settings | PoE Status reflects:

Blue: AT Device
Green: AF Device
Red: Port Disabled
Grey: Port OFF or OPEN

Real-time power consumption monitor showing the total power available, the maximum power threshold percentage, and the percentage of power consumed.

Clicking the Information icon displays more information about the ports.

b) PoE Monitor - lists the ports, and for each port, the power mode, priority, power allocations (mW), power consumption, whether it supports PoE, and an Edit icon for the PoE ports.

Configuring Power Settings for a Port:

Navigate to MANAGE | System Setup | Network | PoE Settings.
Scroll to the PoE Monitor section.
Select a port on which to configure the power settings.
Click the Edit icon for the port and the PoE port settings dialog will show up.
To enable power on the port, select Power Enable.
Choose Power mode from Power mode options.

802.3 AT (default)
802.3 AF
Select the priority using Port priority level radio button.

High
Low (default)
Click OK.

Event logging:

The logs show the detection, classification and state change of the port in logs.

Limitations on TZ 300P to look out for:

If an AF and AT device is connected simultaneously to the TZ 300P PoE ports, it will power ON only one of them base on port priority, It will indicate those errors in red and hovering over those tool tips will provide you more info.
If two AT devices are connected simultaneously to the TZ 300P PoE ports, it will power ON only one of them base on port priority, It will indicate those errors in red and hovering over those tool tips will provide you more info.
