The H801SCUF is a super control unit board. It is the core of the system control, service switching, and aggregation. The H801SCUF can also function as the management and control core of the integrated network management system (NMS). The H801SCUF communicates with service boards about the key management and control information through the master/ slave serial port and inband GE/10GE channel. In this manner, the H801SCUF configures, manages, and controls the device, and also implements the simple route protocol function.
Working principle of the H801SCUF board：
The basic working principle of the H801SCUF board is as follows:
* The control module manages the entire board and the service boards, and communicates with the fan tray through the extended serial port.
* The power module supplies power to other functional modules of the board.
* The clock module provides clock signals for other functional modules of the board.
* 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:
* The H801SCUF control board supports the GICK board (an upstream board
with two GE ports), but only the first GE port on the GICK board is available.
In addition, the GICK board must be a version released later than April 2010.
* The H801SCUF control board does not support the X2CA board.
– Either the four GE ports in the first upstream slot or the GE ports on the H801SCUF
control board can be selected through the electronic switch for upstream
transmission.
* On the MA5600T, when the GICD/GICE/GSCA/GICK board is configured in
slot 19, the GE ports on these boards cannot be used together with GE Front
Panel Port of the H801SCUF control board. For the 10GE upstream board
such as X1CA, there is no such restriction. That is, the 10GE ports on these
boards can be used together with the GE Front Panel Port of the H801SCUF
control board.
* On the MA5603T, when the GICD/GICE/GSCA/GICK board is configured in
slot 8, the GE ports on these boards cannot be used together with the GE Front
Panel Port of the SCUF control board. For the 10GE upstream board such as
X1CA, there is no such restriction. That is, the 10GE ports on these boards can
be used together with the GE Front Panel Port of the SCUF control board.
Either the last of the four GE ports in the second upstream slot or the daughter
board attached to the SCUF control board can be selected through the electronic
switch.
* On the MA5600T, when the GICD/GICE/GSCA board is configured in slot
20, the fourth GE port on these boards cannot be used together with the
daughter board attached to the SCUF control board. When the GICK board is
configured in slot 20, only the first GE port on the GICK board is available.
For the 10GE upstream board such as X1CA there is no such restriction. That
is, the 10GE ports on these boards can be used together with the daughter
board attached to the SCUF control board.
* On the MA5603T, when the GICD/GICE/GSCA board is configured in slot 9,
the fourth GE port on these boards cannot be used together with the daughter
board attached to the SCUF control board.
When the GICK board is configured in slot 20, only the first GE port on the GICK board is available.
For the 10GE upstream board such as X1CA, there is no such restriction. That is, the 10GE ports on these boards can be used together with the daughter
board attached to the SCUF control board.
