3 The system downloads the Dell Networking OS image from the file 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.

b If the Dell Networking OS image versions are different, the system stores the downloaded Dell Networking OS image in local
flash memory and loads the Dell Networking OS image from flash. This process repeats until the Dell Networking OS image
versions match.
The system looks for the configuration file on the file server. If the system does not find a configuration file, the download fails. If the Dell
Networking OS image processing is successful, BMP stops. If the Dell Networking OS image download also fails, the current offer is
treated as invalid and BMP tries to send DISCOVER messages.
Reload with a DHCP Server Offer Without a DNS Server
To reload the Dell Networking OS on a switch using a pre–configuration script, the following must be true:
• BMP is enabled.
• The download of the script is from an external server and the location is specified in the DHCP offer.
• The first 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 Networking OS also supports pre–configurated scripts in Perl, Python, and Ruby.
#!/usr/pkg/bin/perl
#!/usr/pkg/bin/python
• After the first line, but before the start of the script, the script contains the signature #/DELL-NETWORKING.
• The pre–configuration script downloads instead of the configuration file.
• The pre–configuration script runs before applying the start-up configuration file.
• The pre–configuration script can use the Dell Networking OS CLI commands using the f10do utility.
• When the pre–configuration script completes, the start up configuration file automatically applies.
