#1) that's what I was thinking, what level is the switch and is it certified for FICON, also, is the port on the switch setup for the correct protocol ? also, what device is this channel attached to , new DASD , or tape? are the LCU's defined or configured for FICON and nor fiber connected ?

The problem regards >two channels, we also changed the cable for one of them. These might be silly questions but- 1. Is the installed FOS Release on DCX a Ficon Supported and Certified Release?. 2.
