Quidway® NetEngine 40 Series Universal
Switching Router Route Switching Units
Overview
The Route Switching Unit (SRU) is the core of the Quidway® NetEngine 40 universal
switching router (USR) series (abbreviated as NE40).
NE40-8 and NE40-4 provide 2 slots, where one or two SRUs can be located. It is suggested
that you configure two SRUs in order to implement SRU redundancy and enhance system
reliability. NE40-2 has only one SRU slot, so it does not support SRU redundancy.
CR-SRUB
CR-SRUE
When the active SRU runs normally, the standby one is backing up such information in real
time as data configuration and status of slot, board, interface, power, fan and protocol. When
the active SRU is seriously faulty or is reset manually, the system restores services on the
standby one (automatically or by command). Meanwhile, it generates an alarm and records
the switchover cause and process in the log file which will be notified to the NMS.
