to process traffic. The loop status (that is, port blocking and LED blinking) is cleared if
the switch does not detect the loop for a period of about 16 seconds.
To enable loop prevention:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired network connection, or connect directly to a switch that
is off-network using an Ethernet cable.
2. Launch a web browser.
3.
In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Access the switch using a web
browser on page 7.

Manage power saving options
You can manage the IEEE 802.3az Energy Efficient Ethernet (EEE) function, cable length
power saving, or link-up and link-down power saving, or a combination of these features:
•
Short Cable Power Saving. Dynamically detects and adjusts power that is required
for the detected cable length.
•
Link-Down Power Saving. Reduces the power consumption considerably when
the network cable is disconnected. When the network cable is reconnected, the
switch detects an incoming signal and restores normal power.
•
EEE. Combines the Energy Efficient Ethernet (EEE) 802.3 MAC sublayer with the
100BASE-TX and 1000BASE-T physical layers to support operation in Low Power
Idle (LPI) mode. When LPI mode is enabled, systems on both sides of the link can
