Power Supply LEDs

RAS tickets typically report all problems related to power supplies. You
can also observe the blinking pattern of LEDs on power supplies to see if
the they are functioning appropriately.
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.
Use
Table 1

Fibre Port Link Status
Green
LIP and activity
• Solid on — Loop initialization protocol (LIP) has
occurred.
• Blinks at regular intervals — Host command/data
activity is occurring.
Amber
Online and light detected
• Solid on — The library has enabled the tape drive data
bus, and it can detect light through a fibre optic cable.
No color
No activity or no light
detected
• Solid off — Either the tape drive is off or the tape drive
cannot detect light through a fibre optic cable (which is
equivalent to a missing fibre cable). If the tape drive is
offline, the tape drive’s blue status LED will be solidly
lit.
