Your Nighthawk switch has a power saving mode that enables IEEE 802.3az Energy Efficient Ethernet (EEE) function, cable length power saving, and link-up and link-down power saving:
- EEE. EEE is a standard that allows physical layer transmitters to consume less power during periods of low data activity by going into Low Power Idle (LPI) mode.
Your switch might respond more slowly than usual when waking from LPI mode. - Short cable power saving. Some amount of power is always wasted when it is sent over a cable. More power is wasted over longer cable lengths, so devices must request more power than they need in order to make up for the potential shortfall. With short cable power saving, the switch dynamically detects connected cable length and reduces power consumption for shorter cable lengths.
- Link-down power saving. The switch reduces its power consumption when the network cable (uplink) is disconnected. When the network cable is reconnected, the switch detects an incoming signal and restores normal power.
Power saving mode is disabled by default because it slows your switch’s initial response time. If you need the best possible response time, do not enable power saving mode. If you do not care about slightly slower response time, power saving mode can help to reduce your energy usage.
To manage the power saving mode on the switch:
- Open a web browser from a computer that is connected to the same network as the switch or is connected to the switch directly through an Ethernet cable.
- Enter the IP address that is assigned to the switch.
The login page opens. - Enter the switch password.
The home page displays. - From the menu at the top of the page, to the right of NETGEAR, click the icon with three dots and select Power Saving.
- Enable or disable power saving mode by clicking the slider.
When the power saving mode is enabled, the slider displays blue. When the power saving mode is disabled, the slider displays white.
