Channels and channel adapters no longer supported on z990

The following channels and/or channel adapters are no longer supported:

Parallel channels - an ESCON converter is required; IBM 9034 or Optica 34600 FXBT

OSA-2 adapters - use equivalent OSA-Express adapt- ers, for FDDI use 1000BASE-T or Gigabit Ethernet with appropriate multi-protocol switch or router

OSA-Express ATM - use 1000BASE-T or Gigabit Ether- net with appropriate multi-protocol switch or router

4-Port ESCON cards - will be replaced with 16-port ESCON cards during upgrade

FICON (pre FICON Express) - will be replaced with FICON Express during upgrade

PCICC - replaced with PCIXCC for most functions

The fi rst ICB-2 or 3 required a slot. The second to the fourth required another slot. The fi fth to the sixth required another slot. (STI - 2/3 cards each supports two ICBs)
