Power On
Plug the female connector of the provided power cord into the power socket of the device and plug
the positive connector into a power outlet as the following figure shows. Make sure that the voltage
of the power supply meets the requirement of the input voltage (100-240 V~ 50/60 Hz).

Connecting to Power Supply
Note:
1. The figure is to illustrate the application and principle. The provided plug, socket and/or
module in your region may differ from the figures above.
2. Generally PWR1 takes priority over PWR2.

Initialization
After the device is powered on, it begins the Power-On Self-Test. A series of tests run automatically
to ensure the device functions properly. During this time, its LED indicators will respond in the
following order:
1. The PWR LED indicator lights on all the time. The SYS LED and the LED indicators of all the ports
keep off.
2. After about one minute, the SYS LED and LED indicators of all the ports will flash momentarily and
then turn off.
3. Several seconds later, the SYS LED indicator will flash, which represents a successful initialization.

Stack Topology
With stackable design, the switches can be stacked into one stack topology for higher reliability,
larger bandwidth, and simpler networking. To build the stack topology, you need to prepare 2-4
switches and enough SFP+/SFP28 modules/cables. For more details, see the table below:
