Working Principle
Figure 3-9 Working principle of the H801SCUF board
The basic working principle of the H801SCUF 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 16 GE ports to implement GE switching on each service board
– The switching module provides four GE channels and one 10GE channel for each
upstream slot, generally corresponding to an upstream board with four GE ports
(GICD, GICE, or GSCA) or an upstream board with a 10GE port besides the
following situations:
