Installation Prerequisites
ciscoBus Configuration Considerations
Before installing the CSC-MEC in the card cage, ensure that you have the correct type of ciscoBus
controller installed (CSC-CCTL or CSC-CCTL2) and that the ciscoBus interface cards will be
placed in the correct slots per the slot priority requirements described in "Slot Priority," on page 11.
ciscoBus Controller Compatibility
All ciscoBus interface cards, which are listed in Table 3, contain card-specific firmware (microcode),
which determines whether the card is compatible with the first- or second-generation ciscoBus
controller, as follows:
•
•
•
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 CSC-CCTL2. With the
exception of a revision 5.0 CSC-MEC card (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 CSC-MEC card to Version 10.0, the name of the card also changes
from CSC-MEC to CSC-C2MEC to indicate that it is CCTL2-compatible. When you replace a
CSC-CCTL ciscoBus controller with a CSC-CCTL2 ciscoBus controller, you must upgrade the
microcode on all ciscoBus interface cards to Microcode Version 10.0 or later and replace the
CSC-CCTL with a CSC-CCTL2.
Note Only Revision 5.1 or later CSC-MEC cards can be upgraded to a CSC-C2MEC. If you have
a Revision 5.0 CSC-MEC, contact a customer service representative.
You can display a description of the current ciscoBus controller and ciscoBus interface cards with
the EXEC command show controller cbus, an example of which is described on page 8.

1. The C2 designator indicates that these cards are compatible with the CSC-CCTL2 ciscoBus
controller card. The CSC-C2CTR and CSC-C2FCIT cards are shipped (by default) with
Microcode Version 10.0 or later.
2. Only CSC-MEC card revision 5.1 or later is compatible with the CSC-CCTL2
10 Installing the CSC-MEC and CSC-C2MEC Multiport Ethernet Controller Cards
ciscoBus cards with microcode versions earlier than 10.0 are compatible only with the
first-generation ciscoBus controller (CSC-CCTL, controller type 3.0).
ciscoBus cards with Microcode Version 10.0 or later are compatible only with the
second-generation ciscoBus controller (CSC-CCTL2, controller type 6.0).
The CSC-C2CTR and CSC-C2FCIT are compatible only with the CSC-CCTL2. The initial
release of both cards contains Microcode Version 10.0.
