The power supply modules (4＋1 redundancy) can ensure at least 7200W output.
The number of modules used depends on the number of BTRMs.
Two power supply modules (one standby) should be configured when there are no
more than 3 BTRMs. One more power supply module is needed for every 3 new
BTRMs added.
Since current equalization output and centralized powering is used, power supply
modules can be inserted in any slots of the basic cabinet and extended cabinet.
The configuration of power supply modules in a basic cabinet is as follows.
