Quidway® NetEngine 80E Core Router
Switch Fabric Unit
The Switch Fabric Unit (SFU) on the Quidway®NetEngine 80E core router (“NE80E” hereinafter)
completes service data switching of the entire system.
The NE80E provides 22 slots in total, four of which are reserved for the SFU. It is suggested to
configure four SFUs in order to reach 640Gbps switching capacity and enable the redundancy
function of the SFU. Each SFU is a switching plane. When four SFUs are configured, they work in
the 3+1 load sharing mode. Therefore even if a SFU is damaged or replaced, its service will be
resumed on another 3 SFUs automatically to prevent interruption of service data transmission.
The SFU has separate channels to monitor its voltage and temperature and provide
over-voltage/overheat alarm and over-current protection. In addition, the on/off state and sequence
of its working power supply can be controlled.
The SFU currently supported by the NE80E is CR52-SFUA. It has no external interfaces but only
three external indicators indicating the board operating status.
