Hi Pete,

Hope all is well my friend!

This type of error can be caused when combining the 2.iso files. Check that the "final" filename is correct :) This example is for 7.0(2) but I'm sure that you get the idea.

Because of its size, the UCSInstall iso file, UCOS_7.0.2.20000-5.sgn.iso, comprises two parts:

• UCSInstall_UCOS_7.0.2.20000-5.sgn.iso_part1of2

• UCSInstall_UCOS_7.0.2.20000-5.sgn.iso_part2of2

Procedure

Step 1 From www.cisco.com, download the two UCSInstall files.

Step 2 To reunite the two parts of the file, execute one of the following command.

Note Because the 7.0.2.20000-5 build is a nonbootable ISO, it proves useful only for upgrades. You cannot use it for new installations.

a. If you have a Unix/Linux system, cut and paste the following command from this document into the CLI to combine the two parts:

cat UCSInstall_UCOS_7.0.2.20000-5.sgn.iso_part1of2 UCSInstall_UCOS_7.0.2.20000-5.sgn.iso_part2of2 > UCSInstall_UCOS_7.0.2.20000-5.sgn.iso

b. If you have a Windows system, cut and paste the following command from this document into the

command prompt (cmd.exe) to combine the two parts:

COPY /B UCSInstall_UCOS_7.0.2.20000-5.sgn.iso_part1of2+UCSInstall_UCOS_7.0.2.20000-5.sgn.iso_part2of2 UCSInstall_UCOS_7.0.2.20000-5.sgn.iso

Step 3 Use an md5sum utility to verify that the MD5 sum of the final file is correct.

Hope this helps!
