3.3.3 Granting Payload Power During Activation of AMC Modules
The granting of payload power during activation of an AMC module is a function of the back-
plane FRU data, the AMC module FRU data, and the standard power module if present. Based
on the AMC modules’ current requirements, and limits defined for the system as well as indi-
vidual slots, module payload power is granted or denied.
If the FRU data is not correct and it is not possible or desirable to modify the FRU data to sup-
port the current activity (e.g. for tests only), the CLI command ‘currentopts’ and the IPMI OEM
command ‘Set Current Options Parameters’ are available to manually set current parameters.
During the activation of modules, all current capacity problems are reported via a status indi-
cation. The following indications are possible if backplane FRU data are not found:
The following indications are possible if backplane FRU data concerning current is available or
current data is manually defined but the values being offered are not sufficient:
Please note that the sequence of power grants or power denials may differ from the activation
sequence of the modules or rather the slots.
Please note that an AMC module whose FRU data is missing or in whose FRU data the current
requirement record is missing or contains the value of 0 [100mA] will never become activated.
It is possible to switch off all current restrictions being described above by switching off the cur-
rent mode. CLI command ‘currentopts’ and the IPMI OEM command ‘Set Current Options Pa-
rameters’ may be used for that. Please note that this is not recommended for normal operation
and may cause an overload of power modules and contacts.
3.4 Temperature Regulation
Temperature regulation is normally active as soon as the backplane’s configuration parameter
is automatically set. Manual activation or deactivation can also be accomplished by issuing the
CLI command “eopts” or the IPMI command “Set Environmental Options Parameter”.
The regulation parameters can be displayed or set by issuing the CLI command “tcp” or the
OEM IPMI commands “Set Event Driven Temperature Control Parameter” and “Get Event
Driven Temperature Control Parameter”.
When the temperature regulation is deactivated, the fan speed can be manually set by issuing
the CLI command “fan” or the OEM IPMI command “Set Fan Speed Parameter”. As long as the
temperature regulation is deactivated, the previously set fan speed remains in effect.
