Replacing hardware
Compendium Part D - Operation and Maintenance (V9.0)
36 Operating Manual, 02/2018, A5E43228948-AA
There are two scenarios for deploying modules compatible as replacements:
●
Scenario 1: With configuration changes
Can the new hardware be operated within the present PCS 7 version with the full range
of functions?
In this case, the new hardware can be configured with additional software components.
This gives users the opportunity to use new functions.
This scenario is described with an example in the section "Use of new hardware
(Page 37)".
●
Scenario 2: Without configuration changes
When replacing hardware, does the new hardware have to be used without new
functions?
The following applies: The old hardware component has been configured and the new
hardware component which is compatible as a replacement is then deployed.
This scenario is described with an example in the section titled "Deploying new hardware
as replacement (Page 40)".
If a redundant component fails and a successor module or a new hardware or firmware
version is introduced, the partner component must also be upgraded to the same type. See
the section titled "Procedure for replacing hardware (Page 41)" for more information.
You need to determine if scenario 1 is applicable for the PCS 7 version you are using. If this
is not the case, scenario 2 applies automatically. Use the checklist to perform the check for
each type of module according to the section titled "Replacing hardware".
Note
The replacement part scena
rio (scenario 2) is always possible, even if new functions
(scenario 1) could be used but you do not wish to change the configuration.
