Max Power Limit" and "System AC Power Warning Threshold (2500 - 7130)"
field on the User Interface as "Power Warning Threshold".
In addition the "System Max AC Power Limit (2768 - 7928)" needs to have the
following detailed explanation:
System Max AC Power Limit is the max AC power that the system is allowed to
draw from incoming AC power supply source. It can be configured by the user
if and only if the value exceeds the AC Power equivalent (i.e. 15% higher
than the DC allocated power value) of the currently allocated DC Power to
Servers and Chassis Infrastructure. If an attempt is made by the user to
configure the value such that it falls below the AC power equivalent of the
currently allocated DC Power to Servers and Chassis Infrastructure the attempt
would not be successful. In other words, users are NOT allowed to configure
an AC power limit that is less than what is currently allocated to the servers
and infrastructure as that would result in blades being automatically powered
down. The DC power allocated to Servers and Chassis Infrastructure can be found
in the User Interface on the Chassis -> Power Management-> Power Budget status
page under Power Budgeting section or via CLI RACADM utility command (racadm
getpbinfo). User can, however, power OFF one or more server(s) to lower the
current DC Power allocation and re-attempt setting a lower value for System
Max AC Power Limit (if desired) or simply configure the limit prior to
powering on the server blades.
NOTE: Please refer to the Datacenter Capacity Planner (DCCP) tool at
www.dell.com/calc for capacity planning.(186670)
* The help for the Power Budget Status page located in the Chassis->
Power Management tab-> Budget Status sub-tab of the CMC user interface
describes the Priority default value as 5. This needs to be 1.
