Physical Characteristics - IBM 990 Reference Manual

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)
