ciscoBus Token Ring Card and Applique Installation and Upgrade Instructions 15
Installation Prerequisites
Compatibility with Other Cards
The CSC-C2CTR will interoperate with any other CSC-CCTL2-compatible ciscoBus cards (within
the limits specified in the section “ciscoBus Port Limitations” on page 10), and with any Multibus
interface card that is compatible with the current system software. However, as new features are
added with system software releases, the microcode on interface cards may need to be upgraded in
order to take advantage of the new features.
For example, the CSC-C2CTR requires a CSC-CCTL2 ciscoBus controller card and System
Software Release 9.1 or later. (See the section “System Compatibility Requirements” on page 6.) If
you are upgrading your system software and ciscoBus controller card to a CSC-CCTL2 along with
this card installation, you must upgrade the microcode on all existing ciscoBus interfaces to Version
10.0 or later and, to ensure that all the features of a software release are available, and you must
upgrade the microcode on existing Multibus interface cards to the minimum versions required for
Software Release 9.1 compatibility.
The Microcode Release Note publication (Part Number 78-1069-xx, where xx is the latest version)
provides the latest information on both the recommended and minimum required microcode versions
for using all cards with Software Releases 8.2 through 9.1. If the latest version implements features
that you are not using in your system, and you already have the minimum required version installed,
there is no requirement to update the microcode. However, new microcode versions occasionally fix
bugs and provide performance enhancements in addition to implementing new features. You will
obtain maximum performance and reliability by upgrading to the recommended version. Refer to
the latest Microcode Release Note publication for current microcode requirements and
recommendations and for a microcode revision history for each card.
Note
To order upgrades or to obtain additional upgrade or compatibility information, contact a
customer service representative as described in the section “Cisco Information Online” on page 35.
To display the current microcode on any interface card, use the show controller command with
appropriate variables (cbus, token, serial, or ethernet). To display the current CSC-ENVM
microcode, use the show environment command (available with Software Release 9.0 and later).
An example of the show controller cbus command is shown on page 7. The following partial
sample display of the show controller mci command shows a CSC-MCI with Microcode
Version 1.10 installed.
router# show cont mci
MCI 1, controller type 1.1, microcode version 1.10
(additional display text omitted from example)
The following partial sample display shows a CSC-ENVM with Microcode Version 2.2 installed.
router# show env
Environmental controller firmware version 2.2
(additional display text omitted from example)
With the required microcode versions installed, the CSC-C2CTR is compatible with the
followingthree currently available Token Ring Multibus interface cards:
•
CSC-2R dual-port 4/16-Mbps Token Ring card
•
CSC-1R single-port 4/16-Mbps Token Ring card
•
CSC-R16M single-port 4/16-Mbps Token Ring card
