Power On 

Plug one end of the AC power cord into the power connector of the Switch and the other end into the local power source 

outlet.  

After the Switch is powered on, the LED indicators will momentarily blink. This blinking of the LED indicators represents a 

reset of the system. 

Power Failure 

As a precaution, in the event of a power failure, unplug the Switch. When power is resumed, plug the Switch back in. 

The Optional Module 

At the rear of the DXS-3350SR resides an optional module slot. This slot may be equipped with a 2-port 10GE XFP Uplink 

Module, sold separately. Adding the DEM-420X optional module will allow the administrator to add 2 fibre-optic ports 

which will transmit information at a rate of 10 gigabits a second. These two ports are compliant with standard IEEE 

802.3ae, support full-duplex transmissions only and can be used with XFP MSA compliant transceivers. To install the 

module in the DXS-3350SR, follow the simple steps listed below. 

CAUTION: Before adding the optional module, make sure to disconnect all power 

sources connected to the Switch. Failure to do so may result in an electrical shock 

which may cause damage, not only to the individual but to the Switch as well.
