a. Always use the storage management software (TPSSM7) to precisely identify a failure.
b. If nothing is connected to the corresponding connector, this fault light is on. If a cable is connected and it is functioning properly, this light is off.
c. This indicates a problem only if a GBIC is plugged into the corresponding connector (see footnote a). Also, more than one Bypass indicator
will be on if the connection fails. Usually, if a GBIC fails, its Bypass indicator will come on, as will the Bypass indicator of the GBIC to which
it is connected.
d. The Overtemp indicator comes on if the internal drive enclosure temperature reaches 40˚ C (104˚ F). See Chapter 6, "Overtemp Condition" for
more information on the overtemp condition.
007-4304-003
Note: The normal operating state of all indicators on the rear panel is green (blinking if
the drives are processing data). If an amber indicator is on, or a green indicator is off, use
the storage management software (TPSSM7) to determine the nature of the fault and the
recovery procedure.
Exception: If the drive Fault indicators are blinking, it means that the storage
management software (TPSSM7) is locating a drive enclosure component. It does not
indicate a failure.
