It wont fry the receiver but it could possibly damage the switch as it is rather delicate, basicly the power supply has to go to receiver port feed number one on the switch, the sat ports are labeled as 1A 1B 2A 2B 3A 3B.
1A 1B = sat 119
2A 2B = sat 110
3A 3B = any sat of your choice other than 105 and 121 fss.
Its best to use 3 legacy dual lnbfs on this switch.
