Adding and Replacing Hardware
This appendix provides procedures for adding and replacing components in your Avid ISIS. Avid
ISIS hardware additions and replacements are to be performed by Avid ISIS Avid Certified
Support Representatives (ACSR).
Do
not
add any hardware if there are any issues with the system. Correct all problems before
adding new hardware and making changes to the system, perform a quick checks to be verify that
the system is in good working order, see
Adding Hardware
Use the following guidelines if a switch replacement is required. Typically hardware
replacement be performed
after
the software upgrade to avoid unnecessary downgrade and
upgrades of the firmware.
Be aware that all switch firmware is not compatible. Incompatible firmware does not stack
together and therefore cannot be upgraded in the normal manner. As a general rule, v1.0
x
firmware switches do not stack with v1.1, v1.2, v1.3 and later switches and vice versa. Older
v1.1
x
switches will usually stack with newer rev 1.1
x
switches.
Avid ISIS ships with a standalone firmware Avid ISIS Upgrade Utility which is suitable for
upgrading (or downgrading) any firmware version of switch. This utility should be on hand for
any upgrade if the normal upgrade procedure fails for any reason. This utility can be found in the
Avid ISIS software kit in a folder called
\AvidISISUtilities\ISIS 7000\
. For details on the
use of this utility, see
“Running the Avid ISIS Upgrade Utility” on page 171
For more details on compatibility between firmware versions, search the online Knowledge Base
at
for “ISIS firmware matrix.”
If you are replacing an existing switch in the stack, you do
not
need to add/remove chassis or do
anything to the stack. Use the following procedure to swap a switch.
