Example Of The Cabling On A 48-Way System - IBM RS/6000 SP Problem Determination Manual

Figure 43 on page 90 gives an example of the cabling for a 3-switch system
without using intermediate switch boards.

The exact cabling configuration will be addressed later (that is, which jack
connection goes to which node or other jack connectors on other switches), but
first the internal cabling on the switch board will be covered.
4.1.1 Software Overview
The High Performance Switch can be run at both PSSP 1.2 and PSSP 2.1. The
SP Switch, though, can only be run at PSSP 2.1 and only with a certain level of
maintenance applied. To check your current level of maintenance, execute:
# lslpp -l | grep ssp
If you have to install the SP Switch, ensure that the following two products are at
least at the levels specified below:
ssp.basic
ssp.css
This level of code is known as PTF set11. In fact, the levels should be higher
than this to avoid the known problems that can be associated with
newly-supported devices.
If the High Performance Switch is installed, the level of maintenance shown
above (ssp.basic 2.1.0.10 and ssp.css 2.1.0.8) is perfectly valid. It provides
support for both types of switches.
You may also use
installed on the nodes and on the Control Workstation.
