3.1 Installation Preparations
Before installing ZXR10 T8000 cluster 2+8, check the installation environment and
prepare related technical documentation, tools, and qualified installation personnel. For
details, refer to section "Installation Preparations" in the
ZXR10 T8000 Carrier-Class
Router Installation Manual (Single Machine)
.
Before cluster connection, ensure that each ZXR10 T8000 single machine is installed
completely. For detailed installation procedure and caveats, refer to the
ZXR10 T8000
Carrier-Class Router Installation Manual (Single Machine)
.
In addition, ensure that sufficient cluster dedicated fibers are ready and related cluster
boards are installed.
3.2 Installation of Cascade Connection Cables
3.2.1 Installing Cascade Data Cables
The cascade data cables in the ZXR10 T8000 cluster are optical cables. It is required
that the cascade interfaces of each cascade switching network board (MSPU) on a line
card shelf (LCC) be connected to the cascade interfaces of a central switching network
board (CSFU) on a central switching shelf, so as to form a three-level CLOS switching
architecture. Thus, network processing boards (PFUs) on different line card shelves can
switch data smoothly.
Each MSFU on an LCC provides 8 cascade interfaces. One LCC provides up to 4 MSFUs.
That is, one LCC provides up to 32 cascade interfaces. Each CSFU on a CFC provides 8
cascade interfaces. One CFC provides up to 16 CSFUs. That is, one CFC provides up to
128 cascade interfaces.
The data plane cascade connections of the ZXR10 T8000 cluster 2+8 system are as shown
in
Figure 3-1
. The interfaces on an LCC are connected to the interfaces of the same color
and number on the CFC.
