NOTE:
A new or replaced BBU takes at least 7 hours to charge to its full
capacity. Reset the subsystem whenever a BBU is added in order for the
new BBU to take effect.
NOTE:
The life expectancy of a BBU is more than one year. Follow the
procedures above to replace an old BBU with a new one in order to
maintain fault-tolerant subsystem functionalities.
5.5. Replacing a Faulty PSU Module
5.5.1 PSU Module Overview
•
Two (2) redundant PSU modules:
The AR3016G is preinstalled with
two (2) 530W, fully redundant, hot-swappable PSU modules. These
modules are located at the rear of the subsystem.
•
PSU canister:
Each PSU module is housed in a robust steel canister,
with the power supply converter unit in the front and two serially-
aligned cooling fans in the rear section. When the PSU is removed
from the chassis, the cooling module is also being removed.
•
PSU printing mark:
Before you insert a new PSU, be sure that it has
the same printing mark on its handle as that shown on the handle of a
remaining PSU. Double-check to avoid mixing a PSU of previous
EonStor series. (See
Figure 5-11
)
