Resetting lifetime
When operating the system, if Management Blade information is lost, it is necessary to reset lifetime.
Calculation is as follows: Enter the calculated value in Time Limited Count (lifetime) for the PSU and
dummy PSU.
Lifetime= 35000 - months of use

When the system running for eight hours per day and twenty days per month loses information after
four months of use:
Lifetime = 35000 - months of use (4)

The lifetime of the PSU and dummy PSU is suspended only when the main power of this Chassis is
disconnected.
The following shows the lifetime for non-durable components in this Chassis. Use them as a rough
estimate.
Note that the values listed below correspond to a temperature environment ranging from 10-35
°
C. These
values will drop by approximately half with a 10
°
C increase in temperature.
The lifetime of non-durable components fluctuates according to the ambient temperature. The lifetime of such
components is calculated on the assumption that the Chassis is used at an annual average temperature of 25
°
C.
Thus, if the Chassis is used in an environment where the annual average temperature exceeds 25
°
C, the lifetime
can be shorter.
In general, if the temperature increases by 10
°
C (i.e. an annual average temperature of 35
°
C), the lifetime of non-
durable components will be reduced to approximately half.
Do not change the lifetime. If changed replacement notification may not be performed correctly.
Only change the value when running hours information has been lost. Running hours information is
lost only when the front control board of the Chassis is replaced.
