Installation Prerequisites

System Compatibility

Following are the physical requirements and limitations that you must consider before installing new
FDDI components in your system. For example, to obtain optimum performance, you must ensure
that the new components are compatible with the existing system configuration and that you place
interface cards in the proper card-cage slots.
Your AGS+ must meet the following general compatibility requirements before you install a
C2FCIT card and associated appliques:
•
•
•
•
•

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) is a discharge of stored static electricity that can damage equipment
and impair electrical circuitry. It occurs when electronic components are improperly handled and can
result in complete or intermittent failures.
Following are guidelines for preventing ESD damage:

8 Installing and Upgrading the CSC-C2FCIT FDDI Card and Appliques
Your AGS+ has a CSC/3 (or later) processor card running Software Release 9.1 or later.
An applique card cage (Product Number MAS-CCG) is installed in the chassis with at least one
empty slot available, or you received a new card cage in which the FDDI applique is already
installed.
The currently installed ciscoBus cards meet the rules provided in the section "Slot Priority" on
page 9.
You have a second-generation ciscoBus card (CSC- CCTL2) installed; the first-generation
ciscoBus (CCTL) card is not compatible with the C2FCIT card.
Your C2FCIT and CCTL2 cards must have Microcode Version 10.0 or later.
Use the show version command to verify the type of processor card and software release and the
show controller cbus command to verify the microcode versions.
Your site must have the appropriate network interface wiring with which you will connect the
router to your FDDI ring(s).
To operate with the CCTL2 card, all other ciscoBus cards in the AGS+ must have Microcode
Version 10.0 or later (C2FCI, C2HSCI, and C2MEC, and so forth).
The power budget of your chassis will not be exceeded by adding more C2FCIT cards. Current
draw for the C2FCIT and applique is 6.9A (7.7A with any traffic), and the power dissipation is
36W.
Microcode upgrades—If you are upgrading to C2FCIT Microcode Version 10.3, your system
software must be Software Release 9.1(1) or later. For additional information, refer to the section
"Upgrading Microcode" on page 28.
If your current system configuration does not meet all of the above requirements, contact a
Before you open a chassis, ensure that power to the unit is turned off, but that the power cord is
connected to the wall receptacle. Having the power cord connected will ensure a ground path for
any ESD voltages.
Always use an ESD-preventive wrist strap or ankle strap and ensure that it makes good skin
contact.
