When operating in FIPS (Federal Information Processing Standard) Mode, the SonicWALL 
security appliance supports FIPS 140-2 Compliant security. Among the FIPS-compliant 
features of the SonicWALL security appliance include PRNG based on SHA-1 and only FIPS-
approved algorithms are supported (DES, 3DES, and AES with SHA-1).

Select Enable FIPS Mode to enable the SonicWALL security appliance to comply with FIPS. 
When you check this setting, a dialog box is displayed with the following message: Warning! 
Modifying the FIPS mode will disconnect all users and restart the device. Click OK to 
proceed. 

Click OK to reboot the security appliance in FIPS mode. A second warning displays. Click Yes 
to continue rebooting. To return to normal operation, uncheck the Enable FIPS Mode check 
box and reboot the SonicWALL security appliance into non-FIPS mode.

When using the SonicWALL security appliance for FIPS-compliant operation, the tamper-
evident sticker that is affixed to the SonicWALL security appliance must remain in place and 
untouched.
