Chapter 3 Installation of Cluster in 2+8 Mode
3.2.2 Installing Cascade Control Cables
The cascade control cables in the ZXR10 T8000 cluster system are optical fibers. It is
required that the cascade interfaces of each main control board (MPU) on a line card shelf
(LCC) or central switching shelf (CFC) be connected to a central Ethernet switching board
(CESU) on an MPU, so as to form a plane control switching network in which all the MPUs
of the LCCs and CFCs, central switching network boards (CSFUs), cascade switching
network boards (MSFUs), and network processing boards (PFUs) are connected together.
Thus, the cascaded LCCs and CFCs form a unified logical system.
Before installing cascade fibers, reserve a cabling path and space, and prepare sufficient
cascade fibers.
To install cascaded control cables, follow these steps:
1. On an LCC, connect the two cascade GT interfaces of each MPU respectively to the
cascade interfaces of two CESUs, as shown in Figure 3-2 .
2. If the CESUs on different CFCs are mutually backed up, each MPU provide one
cascade GE interface to connect a CESU on another CFC.
3. Interconnect the two CFCs through the 10GE optical interfaces of their CSFUs, as
shown by the thick lines in Figure 3-2 , so as to realize high speed data switching and
load sharing.
4. Stick labels on both sides of the fiber to describe the information about the fiber.
5. Use cable straps to organize and bind the fibers in compliance with related
specifications.
