Hi priteshth,
In order for you to have connectivity from two 5548UP's to one 2148T, you will have to be running vPC. If you do not do this only one N5K will be able to talk to the N2K.
I do not see a problem with this setup on the current version you are running. Just keep in mind that you will need to be running vPC and it will need to be configured on both N5K's.
Here is a link to a vPC configuration guide:
