3 The system downloads the Dell EMC Networking OS image from the le server.
4 The system compares the current local build image to the downloaded build image as follows:
a If the build image versions match, the system does not try to load any image and comes up with the Dell prompt.
00:02:55: %STKUNIT0-M:CP %BMP-5-BMP_RELEASE_HEADER_INFO:

b If the Dell EMC Networking OS image versions are dierent, the system stores the downloaded Dell EMC Networking OS image
in local ash memory and loads the Dell EMC Networking OS image from ash. This process repeats until the Dell EMC
Networking OS image versions match.
The system looks for the conguration le on the le server. If the system does not nd a conguration le, the download fails. If the Dell
EMC Networking OS image processing is successful, BMP stops. If the Dell EMC Networking OS image download also fails, the current
oer is treated as invalid and BMP tries to send DISCOVER messages.
Reload with a DHCP Server Oer Without a DNS Server
To reload the Dell EMC Networking OS on a switch using a pre–conguration script, the following must be true:
• BMP is enabled.
• The download of the script is from an external server and the location is specied in the DHCP oer.
• The rst line of the script contains one of the following:
#!/usr/bin/expect
#!/usr/bin/tclsh
#!/usr/bin/zsh
• If you installed the SmartScripts package, the Dell EMC Networking OS also supports pre–congurated scripts in Perl, Python, and
Ruby.
#!/usr/pkg/bin/perl
#!/usr/pkg/bin/python
• After the rst line, but before the start of the script, the script contains the signature #/DELL-NETWORKING.
• The pre–conguration script downloads instead of the conguration le.
• The pre–conguration script runs before applying the start-up conguration le.
• The pre–conguration script can use the Dell EMC Networking OS CLI commands using the f10do utility.
• When the pre–conguration script completes, the start up conguration le automatically applies.
