Question 1: do i need another Firmwareversion instead of 10.06.2270.00 for MAC?
Answer : VTRAK E610f is a legacy product and no longer under active development. Hence there are no more further updates after 10.06.2270.00 and no other firmware version needed.
Question 2: is it possible to install Non-Mac related Firmware on these Controller Models anyway?
No ,You cannot install Non-Mac related Firmware on those controllers as they are Controller Firmware for Apple. VTrak E610f has two variation controller firmware based on the units (VTrak E610F channel version and VTrak E610f for Apple ) . Both Channel and Mac Firmware version for both controllers are different and we do not recommend mixing different controllers firmware on specific VTrak E610F channel version and VTrak E610f for Apple
Question 3: Installed are CU based SFP for FC. I plan to use LFL. Are there special PROMISE reccomended LWL SFP Models available?
Kindly see below link of the VTrak E610F compatibility list. Attached list are tested and certified by PROMISE. If you do not see the SFPs that you wanted, PROMISE has not tested as well as certified it and we cannot guarantee whether it will work or not.
