Description
to normal mode.
If the system is a dual-bus
system that consists of
Huawei UPSs, set this
parameter to Standard BSC
mode.
After setting this parameter to
Standard BSC mode, you
need to set the two UPS
systems in the dual-bus
system to BSC master
system and BSC slave
system respectively in the
BSC master/slave system
setting. (The two UPS
systems cannot be BSC
master systems or BSC slave
systems at the same time. If
you need to change the
settings in the future, perform
operations under the guidance
of maintenance engineers.)
NOTE
Ensure that the BSC signal cable
between the BSC master and slave
systems is properly connected and
that BSC-related hardware is
properly installed.
Set this parameter based on the
altitude of the place where the
rack is used.
Enable this parameter if a top
outlet fan is configured. Then the
fan running status can be
checked.
Specifies the rack air filter
maintenance interval. If it is set
to 0, there is no reminder.
These two parameters enable the
UPS to control the interval that
each rack (or module) transfers
from battery mode to normal
mode, which reduces the impact
on the generator or power grid. In
the case of battery undervoltage,
the system automatically shortens
the delay for transferring to
normal mode to 1/8 of the normal
