You can validate yourself that correct EoL dates for Cisco WS-C3750G-24TS-E1U are there in the database.
The EoL datafile can be found on your NCM server in C:\ProgramData\Solarwinds\Cirrus\Eos. Open it in an appropriate tool (e.g. SQL Compact Query Analyzer) and run the following query:
select * from Eos where Id in (select EosId from PartNumbers where PartNumber='WS-C3750G-24TS-E1U')
You can see that we have the right data for the above part number:
