Power Supply Leds; Fibre Port Link Led On Tape Drive - IBM TS3310 Maintenance Information

Power Supply LEDs

Operator interventions typically report all problems related to power supplies. You
can also observe the blinking pattern of LEDs on power supplies to see if they are
functioning correctly.
Figure 7-4. Power supply LEDs
Power supply LEDs indicate status by the rate at which they blink. The color of
the LED identifies the area of the component being reported.

Fibre Port Link Status
v Solid ON - Loop Initialization Protocol (LIP) has occurred.
v Blinks at regular intervals - Host command/data activity
is occurring.
v Solid ON - The library has enabled the drive data bus,
and it can detect light through a fiber optic cable.
v Solid OFF - Either the drive is off or the drive cannot
detect light through a fiber optic cable (which is
equivalent to a missing fibre cable). If the drive is varied
OFF, the blue status LED will be solidly lit.
