PCICA		2	4 ports

Maximum combined FICON Express, OSA-Express, PCICA/PCIXCC fea- tures is 20

General Information:

•ESCON confi gured in 4-port increments. Up to 28 chan- nels in 2 cards, 60 channels in 4 cards, 88 channels in 6 cards, etc. up to a maximum 420 channels on 28 cards

•OSA-Express/OSA-Express2 can be Gigabit Ethernet, 1000BASE-T Ethernet or Token-Ring

•Total number of PCIXCC / PCICA is 8 per system

•If ICB-3 are required on the system, these will use up a single I/O slot for each ICB-3 to accommodate the STI-3 cards. The fi rst ICB-3 required a slot. The second to the fourth required another slot. The fi fth to the sixth required another slot. (STI-3 cards each provide two ICBs)

Channels and channel adapters no longer supported on z890

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 migrate to Ethernet as soon as possible

•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

•PCICC - replaced with PCIXCC for most functions

•ICB-2 - replace with ISC-3 links in compatibility mode.
