SRU
The Switch Router Unit (SRU) on the USG9560 is in charge of system
control and route information learning. It is the central control unit of
the device. The USG9560 SRUs work in 1:1 backup mode. When the
active SRU is faulty, the standby SRU immediately takes over for it,
ensuring service continuity.
The USG9560 SRU is integrated with an SFU for data switching.

the SFUs integrated in the two SRUs in 2+1 backup mode for load
balancing.
