The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The N3K-C3548P-10GX is not supported below 6.0(2)A6(1) per the release notes for 6.0(2)A6(1). Currently, CCO's software download section does not delineate the PID between the 3548 and the 3548X. There is always a possibility of a image downgrade due to user error or other reasons.
A sanity check for compatible hardware (3548X/3524X) was added in 6.0(2)A6(3) which will prevent accidental downgrade to unsupported releases (pre 6.0(2)A6(1) )
For scenarios where the software running on the 3548X or 3524X is prior to 6.0(2)A6(3) and a downgrade is executed, you will see the following errors when the chassis is reloaded
POST is completed WARNING! WARNING! WARNING! ************* ####### BKPLANE SPROM CARDID NOT PROGRAMMED ######### This kickstart image is not compatible with * the current hardware platform * Rebooting system * WARNING! WARNING! WARNING! *************
The switch may also drop into a infinite stack trace after reload.
Using the standard break procedure of Ctrl - ] does not work. Ctrl - c does work but loads the invalid kickstart image and breaks into the boot prompt.
In order to recover from this situation, reload the switch and use the key sequence Ctrl - L to interrupt the bios. At this point you should get the loader prompt. Boot and load a compatible kickstart/system image.
