I have questions about VSP G1000 parts differences between,
1. 5559122-B and 5560156-A(QSFP), what is the major differences between this two parts?(manual "PARTS04-40")
2. HDU800-1R6FMSS and HDU800-1R6FNSS(FMD), I think difference is whether battery is installed on FDM or not. Can FMD run without battery?(manual "PARTS04-23)
thanks for help.
