What's the difference between J4859D and the replacement?

Optical and electrical specs follow the same MSA standard; the difference is the EEPROM, which we code as ARUBA before shipping

Does this affect the switch warranty?

The manufacturer cannot void the switch warranty merely because a third-party module is used, unless the module is proven to have caused the damage
