Working Principle
Figure 3-18 Working principle of the H802SCUN board
The basic working principle of the H802SCUN board is as follows:
l The control module manages the entire board and the service boards, and communicates
with the fan tray through the extended serial port.
l The power module supplies power to other functional modules of the board.
l The clock module provides clock signals for other functional modules of the board.
l The switching module provides the GE port and the 10GE port to switch and aggregate
services at Layer 2 or Layer 3.
– Providing four GE ports for upstream transmission using ports on the front panel
– Providing two GE/10GE ports for each upstream boards in upstream transmission
– Providing 16 GE/10GE ports for implementing GE/10GE switching on each service
board
– Providing two 10GE ports for load sharing with the standby control
board(supported in V800R011C00 and later versions)
