Avaya 4524GT, Configuration Manual

Page: 61 / 362

For example, assume the following scenario:
• Ports 1 to 40 are configured as low priority.
• Port 41 is configured as high priority.
• Ports 1 to 40 are connected to powered devices.
The devices connected to the ports consume the available Avaya Ethernet Routing Switch
4500 Series 4550T-PWR,4548GT-PWR, 4526T-PWR and 4526GTX-PWR switch power.
The device connected to port 41 requests power from the Avaya Ethernet Routing Switch
4550T–PWR or the Avaya Ethernet Routing Switch 4548GT–PWR. The switch provides the
required power as port 41 is configured as high priority. However, to maintain the power budget,
the switch drops one of the ports configured as low priority. In this case, the switch drops power
to port 40 and provides power to port 41. If another port drops power, the system automatically
reinstates power to port 40.
Viewing PoE ports using EDM
The front panel view of Enterprise Device Manager (EDM) provides additional information for
PoE ports on the Avaya Ethernet Routing Switch 4548GT–PWR. This additional information
is in the form of a colored P that appears inside the graphic representation of the port. This
colored P represents the current power aspect of the PoE port.
Table 9: Power Aspect color codes on page 61 explains the different colors displayed by the
power aspect.
Table 9: Power Aspect color codes
Color Description
Green The port is currently delivering power.
Red The power and detection mechanism for the port is
disabled.
Orange The power and detection mechanism for the port is
enabled. The port is not currently delivering power.
White/Gray The power and detection mechanism for the port is
unknown.
Important:
The data and power aspect coloring schemes are independent of each other. You can view
the initial status for both data and power aspect for the port. To refresh the power status,
right-click the unit, and select Refresh PoE Status from the shortcut menu.
