
Input Lost Delay
Specify the time in seconds for which the EM card waits until it judges that the input
power to UPSs is interrupted. This allows shutdown of CPU blades due to input power
interruption for a short time to be suppressed. Note that, if the input power to UPSs is
interrupted, then the system is driven by battery. The default setting is "60" seconds.
 Blade Shutdown Timeout
When the EM card provides UPS management, the EM card can direct CPU blades to shut
down at occurrence of input power interruption to UPSs. The item indicates the time for
waiting until the shutdown is completed. The default setting is "300" seconds.

Blade Boot Timeout
When the EM card provides UPS management, the CPU blade which has been shutdown
at input power failure can be rebooted when the input power is recovered. The item
indicates the time for waiting until the power-on is completed. The default setting is "400"
seconds.
NOTE:
Maximum power consumption management is not available
when using automatic CPU blade boot after UPS power recovery.

Communication Lost Delay
Specify the time in seconds for which the EM card waits until it judges no existence of a
UPS after communication with the UPS by SNMP is lost. The default setting is "180"
seconds.
NOTE:
When communication with the UPS is lost, the EM card
judges that the relevant UPS is no longer available. If the number of
UPSs becomes less than those required for normal operation, the EM
card shuts down the CPU blade.

UPS Boot Connect Delay
Specify the time in seconds for which the EM card waits for connections of online UPSs
at system boot. If the number of online UPSs does not reach the specified value within the
time, the EM card calculates the maximum power consumption possible for the system
assuming that the remaining UPSs are not connected.
The default setting is "180" seconds.
NOTE:
Online UPSs mean those in a normal output state (online or
manual bypass state).
