Symbol Access Port Poe Limits; Configuring The Switch Policy - Symbol ES3000 Manual

4-4 ES3000 Advanced Concept Guide
• Limit (W): The maximum power the switch will supply to the port. The Limit parameter can
be set within the range of 3W to 16.5W. Under the web interface, the menu used to set the
power limit shows the Symbol recommended power limits for Symbol Access Ports.
Do not set this value based on the Power display. This displays power currently provided to
the device. The powered devices power requirements can fluctuate above or below the level
currently displayed in the Power parameter, and service will be dropped if power
requirements exceed the limit for the port. The default is 16.5W.
• Power (W): The power currently provided to the device in watts.
• Voltage (V): The voltage currently provided to the device in volts.
• Current (A): The current currently provided to the device in amps.

4.2.2.1 Symbol Access Port PoE Limits

The following table shows the Symbol recommended power limits for some typical Symbol Access
Port configurations.
Under normal operating conditions, actual power use may be less than half of the recommended limit.
The margin is important to allow for rises in power use from high bandwidth usage, exceptional
operating conditions, and manufacturing variation. A reasonable guess for the power limit for a non-
Symbol powered device is twice the actual power draw under typical conditions.

4.2.3 Configuring the Switch Policy

Use the PoE Global Configuration page (Ports > Power Over Ethernet > PoE Global Config.) to set policy
decisions that apply to the switch as a whole, including powered device detection method, power
management method, and power usage threshold.
