Figure 6. VTrak J300s has one or two I/O modules
There can be one or two Input Output Modules (I/O modules) on the J300s unit.
•
If your J300s has two I/O modules, I/O module 1 (on the left) is the default
primary.
•
If your J300s has only one I/O module, that I/O module is the default primary.
Under SAS specifications, both I/O modules are active the same time. The terms
primary
and
secondary
are for enclosure management purposes only. To verify
which I/O module is the default primary, see Chapter 3 of the
VTrak J300s
