range for EPC and APC functionality based on the power supply module
configuration and accurate power control settings.
The following table indicates settings related to the power control
functionality. You can change these settings, except the setting that enables
or disables the DCMI mode, while the server blades are powered on.
However, the management module automatically limits the allowable range
to prioritize the continuous operation of server blades.

Item Description
Power supply module
configuration
Redundancy Setting the power supply module
configuration in the system unit:
•
100VAC: N+N/N+1(default)/N+0
• 200VAC - 240VAC: N+N/N+1(default)
The management module calculates the
available power capacity in the system unit
automatically based on the setting.
Supply power
expansion
Enabling/disabling the supply power
expansion:
• Disable/Enable (default)
The management module calculates the
available power capacity in the system unit
automatically based on the setting.
Emergency
power
control (EPC)
Facility
capping
Enable/
Disable
Enabling/disabling the Facility capping:
• Disable (default)/Enable
When Disable is set, the management module
calculates the available power capacity in the
system unit automatically based on the rating
of power supply module in the system unit.
When Enable is set, the management module
calculates the available power capacity in the
system unit automatically based on the
setting of Facility capping and the rating of
power supply module in the system unit.
Circuit Breaker
rating current
Setting the rating current of circuit breaker in
facility.
• 100VAC : 10A – 100A (default : 15A)
• 200-240VAC : 15A – 100A
(default : 15A when no PDU is used,
default : 30A when PDU is used.)
Number of
Circuit Breaker
Setting the number of circuit breaker in
facility.
• 1/2/3/4
(default=2: for N+N power supply
module configuration
default=1: for N+1 or N+0 power supply
module configuration)
