System Power Control Network (SPCN)
The System Power Control Network (SPCN) option appears on the Hardware Service
Manager display when the system is in the full or limited paging environment.
This option is not available on all systems.
Problems that the SPCN reports to the operating system are logged. Select the
System Power Control Network (SPCN) option to work with the network structure
for SPCN. See the Service Action Log to display and work with the log
information. For more information on SPCN features and use of this option, see
“System Power Control Network (SPCN)” on page 231.
Battery power unit information
The Battery power unit information option is available only on models that do not
have SPCN installed. This option appears on the Hardware Service Manager
display when the system is in the full or limited paging environment.
This option allows you to display the location of the battery power units on the
system and the manufacture dates. It also allows you to update the manufacture
dates when you install or replace battery power units.
Notes:
1. Non-SPCN units may not have an internal battery, and in that case will not
need the battery option set.
2. You do not need to set the date in the Battery Replacement Notice field. It
automatically displays a date which is four years later than the one in the Date
of Manufacture field.
When the system is installed, all input fields appear with an (*) symbol. The
system does not automatically update the battery information. You must manually
enter the manufacturing date for each battery. If no battery is installed, you must
enter blanks in the fields.
