How To Perform A Trace
Various problems can arise when configuring and using the Dell™ PowerVault™ 35F. This section is provided to help
guide the user through some of the basic methods of identifying faults in the setup and configuration of the unit.
Most problems are found in the initial installation. In general, it is wise to check all connections and review the
configuration before proceeding with further trouble analysis. Simplify the installation if possible, reducing it to the
most basic configuration then adding elements one at a time and verifying the operation at each step.
Indicators
The LED indicators on the PowerVault 35F are useful for diagnosing various problems.
The Power indicator turns on when power is applied to the PowerVault 35F. Lack of power indication suggests
the unit being turned off, a problem with the power supplied to the unit, or an internal problem with the unit.
The Fault indicator is lit when the PowerVault 35F detects a fault condition. Faults can occur as a result of
Power On Self Test (POST) failure or operational failures. It is normal for this indicator to flash on when the unit
is powered up or reset. If the fault indicator stays lit, contact DellSystems support.
The SCSI 1 indicator shows SCSI 1 activity when lit. This should only occur briefly during power up or
configuration, and relatively often when the unit is transferring data. If the SCSI indicator stays continually lit
without corresponding target device activity, it may indicate a problem with the SCSI bus configuration. Verify
the SCSI bus configuration.
The SCSI 0 indicator shows SCSI 0 activity when lit. This should only occur briefly during power up or
configuration, and relatively often when the unit is transferring data. If the SCSI indicator stays continually lit
without corresponding target device activity, it may indicate a problem with the SCSI bus configuration. Verify
the SCSI bus configuration.
The Fibre Channel indicator shows Fibre Channel activity when lit. If this indicator fails to light at all, or stays
continually lit without corresponding SCSI bus activity, it may indicate a problem with the Fibre Channel link.
Verify the Fibre Channel Configuration.
The Ethernet indicator signifies Ethernet activity when lit. If the light fails to flicker, or if it stays continually lit,
it may indicate a problem with the network connection. Verify the network connection. The port must be
connected to a 10BaseT Ethernet network to function properly.
Basic Verification
Verify SCSI Bus Configuration
Basic operation of a SCSI bus can be checked by using the configuration menu to view attached SCSI devices. See
Configuring the PowerVault 35F
for more information. Other conditions to look for include:
Termination – Problems with termination can cause intermittent or hard failure. A SCSI bus must be terminated
on both ends, and only both ends.
Bus Type – Single-Ended devices cannot be mixed with Differential devices on the same bus. Similarly, Single-
Ended terminators cannot be used on Differential buses, and Differential terminators cannot be used on a Single-
