For systems that require only single-stage switching, you might want to initially
install an SP Switch Frame if you plan to scale up to a two-stage configuration at
a later date. Switch cabling is much simpler in a two-stage switch configuration,
due to the dedicated switch frame. Installing an SP Switch Frame initially greatly
simplifies future expansion by eliminating the need to re-cable your switch fabric
every time you add another switch.
5.7.1 Switch-to-node cabling
Switch-to-node cables are ordered and shipped with the system according to
configurator rules.
The switch ports in a switch-equipped frame must be connected to all the nodes
in that frame as well as to all the nodes in its non-switched expansion frames.
As an example, consider a Model 550 frame containing four high nodes and an
SP Switch. The switch has 16 ports; the four nodes within that model frame are
connected to four of the switch ports with four 2 meter cables. The rest of the
ports can be used by up to twelve additional nodes mounted in non-switched
expansion frames. In this example, twelve 10 meter cables are provided to
connect the switch to the nodes in the non-switched expansion frames.
Use the following cables to connect switch ports to processor nodes:
F/C 9302 – 2 meter switch-to-node cable (for nodes within the switch-equipped
frame)
F/C 9310 – 10 meter switch-to-node cable (for nodes in non-switched
expansion frames)
The cables may be ordered when configure the processor nodes on SP system.
Use the following cables to connect switch ports to SP-attached servers and
Clustered Enterprise Servers:
F/C 9310 – 10 meter switch-to-node cable
F/C 9320 – 20 meter switch-to-switch cable
The cables for the SP-attached servers may be ordered when you configure the
SP-attached server as a RS/6000 Server attached frame (F/C 9123) and as a
RS/6000 Server attached node (F/C 9122) on the SP system.
The cables for the Clustered Enterprise Servers may be ordered when you
configure the Clustered Enterprise Server as a RS/6000 Server attached frame
(F/C 9123) and as a RS/6000 Server attached node (F/C 9122) on the 9076-555
Standalone Switch for Clustered nodes.
