"HW version is V"

My company has been having a few issues recently where SG300-28A switches 'go dead' to field locations. When they arrive back to us we take a look at them and are prompted for the MAC address, serial number, and hardware version. After a lot of fighting we get it to accept the MAC and serial number in some cases, however the hardware version prompts for a xx.xx.xx format. When I look at the other switches we have they are a mix of 'V01' and 'V02'. If I enter either of these the HW version ends up being accepted as 'V'. If I leave it blank it says the HW version has not been changed and it also says HW version is V.

I have a few questions:

1) Does having the HW version as V create any issues? I would call this the most important question.

2) Is there any way for me to determine the HW version from looking at labels on the exterior of the switch? Obviously the switch no longer knows what it is so I can't pull it from there.

3) Assuming I am able to determine what the original HW version was, is there any way for me to revise it back to the correct version after it has the above mentioned identity crisis?

Thank you in advance for any assistance.
