I'm afraid that you won't "found" (or find?) something like "firmware 3.30" anywhere...
(SCNR, I'm not a native speaker myself
But you can actually find the latest firmware update package for D2616 on FTS's download pages, choosing any PRIMERGY server product that optionally shipped with this controller, e.g. in RX300s8 under this link
Please check the notes which list
FW 2.130.403-4660BIOS 3.30.
EFI driver 6060A0500
Please also follow the additional hint to upgrade with an intermediate step, if the currently installed PACKAGE version is older than 12.9.0-0051, so check ALL&EVERY displayed version information!
