Working Principle
Figure 3-20 Working principle of the H801SCUV board
The basic working principle of the H801SCUV 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. In addition, the control module can be
configured with a built-in CF card to expand its storage space.
l The logic module implements the logic control and stratum-3 clock functions.
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 10GE port and the 20GE port to switch and
aggregate services at Layer 2 or Layer 3.
– Providing four 10GE ports for upstream transmission using ports on the front panel
– Providing two 10GE ports for each upstream boards in upstream transmission
– Providing 16 10GE/20GE ports for implementing 10GE/20GE switching on each
service board
