Cabling for FICON
The FICON interface card used by the CNA-8000 may have 1, 2, or 4 individual FICON
interfaces built in. Each FICON interface includes a transceiver mounted on the interface
card. FICON transceivers come in short wave and long wave versions. Correct
transceivers for the customer’s environment should have been shipped with the platform.
However if the correct transceivers are not installed, it is possible to swap transceivers in
the field. Please refer to the CNA-8000 Users Guide and Maintenance Manual for
information regarding this.
You can do a visual check to compare the transceivers to your environment. Each
transceiver can be viewed from the rear of the unit and checked for color. Transceivers
with black on the bail are short wave and transceivers with blue on the bail are long
wave. Compare this with a visual inspection of the FICON cables being used. Micron
values are typically written on the cable jackets. Values of 50/125 or 62/125 are short
wave cables (usually orange). A value of 9/125 represents a long wave cable (usually
yellow).
The FICON interface card ships with a plastic plug inserted into each FICON interface,
for purposes of keeping dust from the optical leads and to help protect the connector
during shipment. The plastic plug(s) should be left in place until you are ready to attach
the FICON cable(s). When ready, remove each plastic plug and set aside in a safe place
for future use. Insert the FICON cable into the cavity vacated by the plastic plug, and
push in until you hear/feel it click into place. Be careful when handling FICON cables,
and do not bend the cables any more than necessary. The cables are fiber optics, and
bending them too tightly will cause them to break internally, and make them useless.
