General Information:
• ESCON confi gured in 4-port increments. Up to a maxi-
mum 69 cards, 1024 channels.
• OSA-Express2 can be Gigabit Ethernet (GbE),
1000BASE-T Ethernet or 10 GbE.
• OSA-Express can be Gigabit Ethernet (GbE),
1000BASE-T Ethernet or Fast Ethernet.
• If ICB-3 is required on the system, it will use up a single
I/O slot for every 2 ICB-3 to accommodate the STI-3
card.
Note: In the fi rst and second I/O cage, the last domain in
the I/O cage is normally used for ISC-3 and ICB-3 links.
When the fi rst 6 domains in an I/O cage are full, additional
I/O cards will be installed in the next I/O cage. When all
the fi rst 6 domains in all I/O cages are full and no Coupling
link or PSC cards are required, the last domain in the I/O
cage will be used for other I/O cards making a total of 28
per cage.
