Working Principle
Figure 3-14 Working principle of the H801SCUL board
The basic working principle of the H801SCUL board is as follows:
l The control module manages the H801SCUL board and 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/10GE port to switch and aggregate services at
Layer 2 or Layer 3.
– Providing 16 GE/10GE ports to implement GE/10GE switching on each service
board
– Providing two GE/10GE ports for upstream transmission using the upstream board.
– Providing two GE/10GE ports for upstream transmission using the upstream board
(in the second of the two slots for the upstream board). Either the last GE/10GE
port or daughter board can be used for upstream transmission, which is controlled
by the electronic switch.
