3.2 Physical port layout
Before installing the FICON Director, consider where to connect your FICON channels from
the server and the control unit ports, as well as the ISLs (if applicable), based on your
requirements.
Distribute the channels among different FPM/UPM cards.
If two channels are defined to access the same CU, plug both fiber optic cables into
different FPM/UPM cards in the Director.
Distribute the CU ports among different FPM/UPM cards.
If two paths are defined to attach the CU to the server via a Director, connect both fiber
optic cables to ports on different FPM/UPM cards.
Distribute the ISLs across different FPM/UPM cards.
If two or more ISLs are to be attached between the Directors, then connect the fiber optic
cables to ports on different FPM/UPM cards.
Following these simple rules will assure that there is always one path available between the
server and the CU in case of a defective FPM/UPM card in the Director.
Refer to Appendix B., “Port location and mapping” on page 79 for physical port locations, and
port numbering and port addresses on the FPM/UPM cards.
In Appendix C, “FICON Director configuration worksheet” on page 85, you will find a
worksheet to help with documenting the physical layout of your FICON Director(s).
3.3 IP addressing and connectivity
For controlling and maintaining the McDATA FICON Director, both CTP cards in each Director
have connectivity to the EFC Sever via an Ethernet LAN, known as the service LAN. An
Ethernet hub is installed in each cabinet, which is used to connect all the CTP cards and the
EFC Manager workstation.
Although two CTP cards are installed in each Director, only one IP address is required for
both CTP cards. The Ethernet port on the
backup CTP card is deactivated, and only the port
on the currently
active CTP card is activated. In case of a failure of the active CTP card, the
Ethernet port of the backup CTP is automatically activated.
The default IP address for the CTP card is 10.1.1.10, and for the EFC Manager it is 10.1.1.1
with a default subnet mask of 255.0.0.0. The default gateway address is 0.0.0.0.
If the Director and the EFC Sever are to be connected to a corporate network instead of the
service LAN, then their IP addresses and subnetwork mask have to conform to the IP
addressing standard used in the corporate network.
A minimum of two IP addresses are required; one address for the CTP cards, and one
address for the EFC Sever.
If it is required to alter the IP address and/or subnetwork mask of a Director, for example,
when multiple Directors are on the same service LAN, refer to Appendix , “Altering an IP
address in a CTP card” on page 74.
The recommended network configuration for the Director, the EFC Sever, and client
workstation is shown in Figure 3-1.
