Power Supply LEDs 13
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 15 to interpret power supply activity.
Table 15 Power Supply Status
In the RAS tickets associated with the defective power supply, record
both the number of the module and the number of the power supply
connected to that module.
The 9U Library Expansion Modules are numbered according to their
position in relation to the 5U Library Control Module. The 5U Library
Control Module is assigned the number 0. All 9U Library Expansion
Modules stacked beneath the 5U Library Control Module are assigned a
negative number, while 9U Library Expansion Modules stacked above
the 5U Library Control Module are assigned a positive number. For
example, 9U Library Expansion Module -2 is the second 9U Library
Expansion Module beneath the 5U Library Control Module, while 9U
Library Expansion Module +2 is the second 9U Library Expansion
Module above the 5U Library Control Module.
