xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch 
Multiple Image Services 
The Multiple Image Services folder allows users of the Switch to configure and view information regarding firmware located on 
the Switch. The Switch allows two firmware images to be stored in its memory and either can be configured to be the boot up 
firmware for the Switch. For information regarding firmware images located on the Switch, open the Firmware Information link. 
The default setting for the Switch’s firmware will have the boot up firmware stored in Image 1, but the user may set either 
firmware stored to be the boot up firmware by using the Config Firmware Image menu.
