Flashing TRW SFP modules for an HP v1910-24G: matching serial numbers and checksums, or let the supplier reflash
The poster wanted to flash four TRW-1310-1.25C-3 and TRW-1550-1.25C-3 SFP modules to work with an HP v1910-24G (JE006A) and asked about a programmer. The difficulty was finding the right firmware and matching serial numbers within one switch while keeping checksums valid. Hardware involved: HP v1910-24G JE006A, TRW-1310-1.25C-3, TRW-1550-1.25C-3.

A firmware generator resource (sfpdb.freetime.su) was suggested, aolng with rearranging serial-number bytes while keeping checksums valid.
The supplier agreed to reprogram the modules at no chrge, which resolved it.
