Managing Power-Over-Ethernet Devices; Defining Poe System Information - Alcatel OS-LS-6224 User Manual

Managing Power-over-Ethernet Devices

Power-over-Ethernet (PoE) provides power to devices over existing LAN cabling,
without updating or modifying the network infrastructure. Power-over-Ethernet
removes the necessity of placing network devices next to power sources.
Power-over-Ethernet can be used in the following applications:
• IP Phones
• Wireless Access Points
• IP Gateways
• PDAs
• Audio and video remote monitoring
Powered Devices are devices which receive power from the device power supplies,
for example IP phones. Powered Devices are connected to the device via Ethernet
ports.
Guard Band protects the device from exceeding the maximum power level. For
example, if 400W is maximum power level, and the Guard Band is 20W, if the total
system power consumption exceeds 380W no additional PoE components can be
added. The accumulated PoE components power consumption is rounded down for
display purposes, therefore remove value after decimal point.
Note:
Due do hardware limitations, the power measurement accuracy is 4%.

Defining PoE System Information

The Properties Page contains system PoE information for enabling PoE on the
device, monitoring the current power usage, and enabling PoE traps.
Command Attributes
• Unit — Indicates the stacking member for which the PoE information is displayed.
• Power Status — Indicates the inline power source status.
• On — Indicates that the power supply unit is functioning.
• Off — Indicates that the power supply unit is not functioning.
• Faulty — Indicates that the power supply unit is functioning, but an error has
occurred. For example, a power overload or a short circuit.
• Nominal Power — Indicates the actual amount of power the device can supply.
The field value is displayed in Watts.
• Consumed Power — Indicates the amount of the power used by the device. The
field value is displayed in Watts.
• System Usage Threshold — Indicates the percentage of power consumed before
an alarm is generated. The field value is 1-99 percent. The default is 95 percent.
• Traps — Indicate if PoE device traps are enabled. The possible field values are:
• Enable — Enables PoE traps on the device.
• Disable — Disables PoE traps on the device.This is the default value.
