Operating Manual
Troubleshooting
Various problems can arise when configuring and using the PSFR-CP41. 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 PSFR-CP41 are useful for diagnosing various
problems.
The
Power indicator
turns on when power is applied to the router. 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 PSFR-CP41 detects a fault condition.
Faults can occur as a result of Power On Self Test (POST) failure or opera-
tional 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 Siemens support.
The
SCSI indicator
shows SCSI 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 corre-
sponding 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.
