6-2 AlphaServer GS80/160/320 Service Manual
6.1 Drawer Modules
The GS80 system uses the same modules as the GS160/320 systems with
the exception of the global port module and the I/O riser. The functions
of the global port are built into the backplane on the GS80. And the
design of the I/O riser is modified so that it fits in the GS80 drawer.
