Hints and Tips:
Installing and Cabling a
Multinode System x3950 M2
Use these hits and tips in addition to the Rack Installation Instructions manual and
the Scalability Option Kit manuals to cable and setup an x3950 M2 multinode
complex.

Notes on the Scalability Cabling Setup
1.
The deep-plug design of the scalability cables will help to prevent the cables from
becoming disconnected from the port since the connection is actually in the center of
the system, not at the rear of the system like previous System x scalable systems.
2.
Due to the deep-plug nature of the scalability cables, the lengths are actually longer
than previous systems but the actual amount of slack outside the system and the CMA
is slightly less than the slack in the xSeries 460/System x3950 system.
3.
Thinner gauge cable was chosen for this generation of the scalability cables, and a
thinner gauge still will be introduced later in 2008. This reduces the stiffness of the
cables and will help the cables route more easily.
4.
It is recommended to wrap the cable strap around the scalability cables first to secure
them within the brackets, then wrap the strap around the CMA.

8u needed for 2-node system
The length of the scalability cables requires that no empty U-spaces exist between the nodes.

Install slides into rack
Use Rack Installation Instructions manual to space slides appropriately and install the slides into
the rack. Note this system is 4u as opposed to 3u for the original System x3950/xSeries 460.
