(level-noncritical; system does not have
redundant power)
System under recommended voltage for x
(level-warning; indicated voltage supply
under nominal value; value for x can be +12,

1. Check connections to the power subsystem.
2. Power supply.
3. Power cage assembly.
Part/action
1. Ensure that the external SCSI devices were
powered-on before the appliance was powered-on.
2. Ensure that the cables for all external SCSI devices
are connected correctly.
3. If you have attached an external SCSI device to the
appliance, make sure the external SCSI termination
is set to automatic.
4. Ensure that the last device in each SCSI chain is
terminated correctly.
5. Ensure that the SCSI devices are configured
correctly.
