VTrak J830s, J630s Product Manual
To check a power supply's installation, follow the same procedure as replacing
the power supply, except that you reinstall the original rather than a new one. In
most cases, this action fixes a bad connection and allows VTrak to detect the
power supply. If this action does not correct the problem, replace the power
supply.
I/O Module LEDs
The LEDs on the VTrak unit's I/O modules indicate activity on each of its SAS
ports and I/O module status.
Figure 4. The I/O modules have two SAS ports
The I/O module status LED shows red at startup. Within 2 or 3 seconds, it turns
green to indicate that the I/O module is ready.
