NOTE
Currently, the LPUs of the S9300 can be classified into S-series boards, E-series boards, F series boards
and EPON board. The details are as follows:
l The S-series boards include only the SA boards, for example, 24-port 100M/1000M Ethernet optical
interface card (SA, SFP)-32K MAC
l The E-series boards include EA, EC, and ED boards, for example, 48-port 100M/1000M Ethernet
optical interface card (EA, SFP)-32K MAC
l The F-series boards include only FA boards, for example, 48-port 1000M Ethernet optical interface
card (FA, SFP)-32K MAC
l The EPON board provides 12 1000M EPON optical interfaces and 12 100M/1000M optical interfaces
(SFP).
The boards on the S9300 are classified into main control boards, Line Processing Units (LPUs)
and so on. The S9312 and S9306 use the Switch Routing Unit (SRU) as the main control board,
and the S9303 uses the Main Control Unit (MCU) as the main control board. Table 5-1 lists the
names, types, and description of the boards on the S9300.
