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
periodically to check link pulses. This mode reduces power consumption on
the port when no link partner is present. Energy Detect is proprietary and
operates independently from EEE.
Energy Efficient Ethernet
Dell EMC Networking switches support IEEE 802.3az Energy Efficient
Ethernet (EEE) Lower Power Idle Mode on front panel copper ports, which
enables both the send and receive sides of the link to disable some
functionality for power savings when the link is lightly loaded. EEE is
standardized by the IEEE and operates independently of Energy Detect. EEE
requires auto-negotiation to be enabled. Setting a port to a forced speed
disables EEE.
EEE and Energy Detect are supported on the Dell EMC Networking N1100-
ON, N2000, N2100-ON, N3000E-ON, N3100-ON, and N3200-ON Series 1G
copper ports. EEE is supported on Gigabit Ethernet ports 1-8 on the N1108
Series switches, on Gigabit Ethernet ports 5-20 on the N1124 Series switches,
and Gigabit Ethernet ports 9-24 and 29-44 on the N1148 Series switches.
EEE is supported on Gigabit Ethernet ports 1-17 on the N1524 and Gigabit
Ethernet ports 9-41 on the N1548. Energy detect is supported on all Gigabit
Ethernet ports on the N1100 and N1500 Series switches.
EEE and Energy Detect are enabled by default on the N-Series copper ports.
Neither Energy Detect nor EEE are supported on out-of-band, 2.5G or 5G
NBASE-T ports.
