ciscoBus Configuration
Before installing a new CSC-C2CTR, ensure that all ciscoBus interface cards are the C2 type (all
have Microcode Version 10.0 or later installed), that any new ciscoBus cards you are installing will
not exceed the maximum port limits for ciscoBus interfaces, and that the ciscoBus cards will be
placed in the correct order of priority in the ciscoBus slots. The following sections describe how to
determine all of these requirements.
ciscoBus Controller Compatibility
All ciscoBus interface cards, which are listed in Table 1, contain card-specific microcode that
determines whether the card is compatible with the first- or second-generation ciscoBus controller
card. Following are compatibility guidelines:

1. Only CSC-C2MEC Revision 5.1 or later is compatible with the CSC-CCTL2.
The C2 designator added to the name of a ciscoBus interface card indicates that the card is running
Microcode Version 10.0 or later and is, therefore, compatible with the second-generation ciscoBus
controller card, the CSC-CCTL2. With the exception of a Revision 5.0 CSC-MEC (see Note
following), the first- and second-generation ciscoBus interface cards are otherwise the same. For
example, you can upgrade a revision 5.1 CSC-MEC to a CSC-C2MEC by replacing the microcode
with Version 10.0 or later. When you upgrade the microcode on the revision 5.1 CSC-MEC to
Version 10.0, the name of the card also changes from CSC-MEC to CSC-C2MEC to indicate that it

If your system software, ciscoBus controller, or other interface cards in your system do not
ciscoBus cards with microcode versions earlier than Version 10.0 are compatible only with the
first-generation ciscoBus controller card (CSC-CCTL).
ciscoBus cards with Microcode Version 10.0 or later are compatible only with the
second-generation ciscoBus controller card (CSC-CCTL2).
The CSC-C2CTR and CSC-C2FCIT are compatible only with the CSC-CCTL2. The initial
release of both cards contained Microcode Version 10.0.
