Switch compatibility
Issue 1.0 December 2003 9
Switch compatibility
CMS R12 does not support R7 and earlier switches. When upgrading to CMS R12, the
switch must be at least R8 or later. If the current switch is administered in CMS as R7 or
earlier, the upgrade extract tool will recognize this incompatibility and require you to select
a newer switch model before the upgrade can continue.
CMS R12 does not support X.25 switch links. The upgrade extract tool will recognize this
incompatibility and require you to enter a host name or IP address and TCP port before the
upgrade can continue. Determine the host name or IP address and TCP port before you
begin the upgrade.
Note:
Note: If the host name or IP address and TCP port information is not known during
the CUE upgrade, you can enter fictitious information to get through the
upgrade, but the switch links will not become active until you go back and
update the switch setup information with accurate information.
Hardware additions
Avoid hardware additions whenever possible during an upgrade. For example, if the
customer wants to increase the amount of RAM that is in the computer, add it only after
verifying that the upgrade was successful. Install the RAM as described in the
maintenance and troubleshooting document for the computer.
