80 Getting Started with the McDATA Intrepid FICON Director

Intrepid port numbering

For the Intrepid (6064 and 6140) FICON Directors, the physical port numbers are the same

as the

port addresses. The Hardware Configuration Definition (HCD) and Input Output

Configuration Program (IOCP) use port address information to define control unit link

addresses. The

physical port number is indicated either by a decimal or hexadecimal value,

which can be found in the ECF Manager logs as identification for a given port. See Figure B-1

for physical port number and port address mapping information.

Figure B-1 Port numbering

This example shows a decimal port number of 45 (x’2D’) and the port address is 31, which is

the address used for HCD and IOCP definitions.

Intrepid 6064 port address mapping

Figure B-2 on page 81 shows the port layout for Intrepid 64-port FICON Director with the

assigned port ranges. Port numbering starts at the left, and continues to the right of the

Director. Notice that the counting of ports starts in slot 0 from the bottom of the card.

Note: A port number may have a different port address assigned if a port swap was

performed.
