GS160/320 System Overview 2-7
The QBB backplanes are attached to a stiffener and mounted in a system box
enclosure. Each backplane has a differently positioned cutout to accommodate
the global port modules. A global port module is mounted on the front of one
QBB and the other is mounted on the back of the other QBB, putting both
global port modules near the distribution board (or the hierarchical switch)
when the system box is installed in the cabinet.
The callouts in Figure 2–4 point to the location of these components in the
system box:
I/O riser module area. Each QBB supports up to two I/O riser
modules.
CPU module and memory module area. Each QBB holds four CPUs
and four memory modules.
Global port area.
Backplane area.
