2.1 Introduction
This section describes the characteristics of the S9300.
Position
The S9300 is a high end Ethernet switch with large capacity and high performance. It mainly
functions as an access node or aggregation node on the metropolitan area network (MAN) or a
core switch on an enterprise network, providing Fast Ethernet (FE), Gigabit Ethernet (GE), and
10GE interfaces.
Types
Three types of S9300 products are available to meet requirements of different users, namely,
S9312, S9306, and S9303.
l 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.
l 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.
l 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
backup.
The S9303, S9306, and S9312 have different capacities and structures but they use the same
software platform, hardware platform, LPUs, and software. Two types of Main Processing Units
(MPUs)are used for the S9300 series:
l SRU: used by the S9306 and the S9312
l MCU: used by the S9303, which integrates the functions of the Centralized Monitoring
Unit (CMU) on the S9306 and S9312.
You can select the product type according to the networking requirements.
Environment Protection Design
l 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.
l 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.
