Service Manual

NOTE: In the pre–configuration script, the DHCP IP address is released after the script executes.
9 The system applies the configuration. The system is now up and running and you can manage it as usual.
10 SHA256/MD5 hash verifies the integrity of the files BMP downloads. For each file, the relevant
filename.sha256 or filename.md5 must be present in the same location as the Dell Networking OS
image – script or configuration file.
a When you disable FCoE initialization protocol (FIPs) mode:
• If both filename.sha256 and filename.md5 are not present, the image is downloaded
without validation.
• If both filename.sha256 and filename.md5 are present, SHA256 validation has a higher
priority compared with MD5 validation.
• If filename.sha256 or filename.md5 alone is present, the corresponding type of validation
is completed.
b When you enable FIPs mode:
• MD5 validation is not used. BMP checks only for the filename.sha256 and not
filename.md5.
• If filename.sha256 is present, it uses SHA256 validation or the image downloads without
SHA256 validation.
• Syslog for SHA256VALIDATION success on downloading an image file and configuration/
pre-script file:
00:03:07: %STKUNIT0-M:CP %BMP-5-BMP_SHA256_VALIDATE_SUCCESS: The

00:01:15: %STKUNIT0-M:CP %BMP-5-BMP_SHA256_VALIDATE_SUCCESS: The

• Syslog for SHA256VALIDATION failure on downloading an image file and configuration/
pre-script file:
