ISC-3 reference
ISC-3 links provide Parallel Sysplex
production systems using z/OS
in peer mode (connection between z10 EC, z10 BC, z9 EC, z9 BC,z990, or z890
systems) at un-repeated distances up to 10 kilometers (6.2 miles).
The table below describes the ISC-3 feature.
Feature Code
Description
FC 0218
2-Port ISC-3
v ISC-3 links are comprised of:
– FC 0218 - A "daughter" adapter card with two ISC-3 ports per card.
– FC 0217 - A "mother" card into which can be plugged two "daughter" cards.
– FC 0219 - LMC that activates the ports on a "daughter" card. Each port on a
"daughter" card is activated individually.
– The "mother" card, two "daughter" cards, and the individual port LMC can
combine to provide up to four ports per ISC-3 adapter.
Note: On an initial system order, any request for more than two ISC-3 ports
automatically generates a minimum of two FCs 0217. This ensures
maximum ISC-3 availability and efficiency.
v The system configuration tool places the ISC-3 feature port LMC across an
appropriate number of cards for high availability.
v See Planning for Fiber Optic Links (ESCON, FICON, Coupling Links, and Open
System Adapters), GA23-0367, for information about link distances and light loss
budget.
The following illustration shows the ISC-3 feature, the links on the daughter cards,
and the type of fiber optic connector that plugs into the transceivers.
