I tried this bat file STGN.bat for AOC-STGN-I2S. But after running it asked LANMAC1\2 SANMAC1\2.
LANMAC1\2 - are macs of port 1 and 2, I guess, And i have no clue what is SANMAC1 and 2
On your AOC-STGN-I2S card, you should see both the LAN MAC1 &2 and SAN MAC1&2 labeled. Please first write them down carefully and accurately (or take a picture), before you proceed the FW update process. Then follow the on-screen instructions to enter the LAN MAC 1, 2 and SAN MAC 1, 2 accurately.
