VLAN.  Otherwise, you can lose network access to the ioSafe R4 and you 
may need to perform a firmware re-installation to disable the VLAN setting.

PERFORMANCE SETTING 
The 
Enable jumbo frames
 option allows you to optimize the ioSafe R4 for large data transfers 
such as multiple streams of video playback.  Select this option if your NIC and your gigabit switch 
support jumbo frames. 
Note 
The ioSafe R4 supports a 7936 byte frame size, so for optimal performance, 
a switch capable of this frame size or larger should also be used. 
Your ioSafe R4 device comes with multiple Ethernet interfaces, you will see a separate configuration 
tab for each interface.
