The Quidway S9303 switch (hereinafter referred to as the S9303) supports double Main
Control Units (MCUs), three Line Processing Units (LPUs), and two AC or DC power
supplies in 1+1 backup.
The Quidway S9306 switch (hereinafter referred to as the S9306) supports double Switch
Routing Units (SRUs), six LPUs, and DC power supplies in 1+1 backup or AC power
supplies in 1+1 or 2+2 backup.
The Quidway S9312 switch (hereinafter referred to as the S9312) supports double SRUs,
twelve LPUs, and DC power supplies in 1+1 backup or AC power supplies in 1+1 or 2+2

SRU: used by the S9306 and the S9312
MCU: used by the S9303, which integrates the functions of the Centralized Monitoring
Unit (CMU) on the S9306 and S9312.
Stopping the chips not in use
When the boards are installed on the S9306 or S9312, the S9306 or S9312 stops the chips
that are used for the S9303 on these boards to save power.
Auto power-down
Chips of the T24XA, G48VA, G24CA, and G48T support the auto power-down function.
When an interface is not connected to the remote end, the chips work in power-saving mode.
When the interface is connected to the remote end, the chips work in normal mode.
