Green Technology Features
For information about configuring Green Technology features, see
"Configuring Port Characteristics" on page 483.
Energy Detect Mode
When the Energy Detect mode is enabled and the port link is down, the PHY
automatically goes down for short period of time and then wakes up to check
link pulses. This mode reduces power consumption on the port when no link
partner is present.
Energy Efficient Ethernet
The switch supports the IEEE 802.3az Energy Efficient Ethernet (EEE)
Lower Power Mode, which enables both the send and receive sides of the link
to disable some functionality for power savings when the link is lightly loaded.
Power Utilization Reporting
The switch displays the current power consumption of the power supply (or
power supplies). This information is available from the management
interface.
Power over Ethernet (PoE) Plus Features
For information about configuring PoE Plus features, see "Managing General
System Settings" on page 271."
Power Over Ethernet (PoE) Plus Configuration
The PowerConnect 7024P and 7048P switches support PoE Plus
configuration for power threshold, power priority, SNMP traps, and PoE
legacy device support. PoE can be administratively enabled or disabled on a
per-port basis. Power can also be limited on a per-port basis.
NOTE:
The PowerConnect 7024P and 7048P switches support PoE Plus. The PoE
Plus features do not apply to the other models in the PowerConnect 7000 Series.
