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 18

to interpret power supply activity.

Table 18 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 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.

Location Represents Power Supply Status

Green

(top)

AC OK • 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.

Green

DC OK • Solid ON — The power supply’s output voltage is within regulation.

• Solid OFF — The power supply’s output voltage is not within

regulation.

Blue
