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 18
Power Supply Status
• Solid ON — The power supply's AC input is above the minimum
requirements to operate.
• Solid OFF — The power supply's AC input is below the minimum
requirements to operate.
• Solid ON — The power supply's output voltage is within regulation.
• Solid OFF — The power supply's output voltage is not within
regulation.
• Solid OFF — Normal.
• Solid ON — Swap mode: Ready to be removed or replaced.
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 expansion modules are numbered according to their position in
relation to the control module. The control module is assigned the
number 0. All expansion modules stacked beneath the control module are
assigned a negative number, while expansion modules stacked above the
control module are assigned a positive number. For example, expansion
module -2 is the second expansion module beneath the control module,
while expansion module +2 is the second expansion module above the
control module.
Each module can have up to two power supplies. The power supply on
the left is #1, while the power supply on the right is #2.
