Diagnostics

3-27

Inspect the switch for indications of being powered on, such as:

• At the front bezel, an illuminated PWR LED (green)

or ERR LED (amber).

• Illuminated LEDs adjacent to Fibre Channel ports.

• Audio emanations and airflow from cooling fans.

Does the switch appear powered on?

YES NO

↓ A power distribution problem is indicated. Go to step 38 to

obtain event codes. If no event codes are found, go to MAP

0100: Power Distribution Analysis on page 3-30. Exit MAP.

A faulty PWR LED is indicated, but switch and Fibre Channel port

operation is not disrupted. The LED is connected to CTP card

circuitry, and if this problem is a concern to the customer, the switch

must be replaced. Exit MAP.

Is the amber ERR LED at the switch front bezel blinking?

YES NO

↓ Go to step 47.

Unit beaconing is enabled for the switch.

a. Consult the customer and next level of support to determine the

reason unit beaconing is enabled.

b. Disable unit beaconing.

1. At the Hardware View (Figure 3-10 on page 3-20), right-click

the front bezel graphic (away from a FRU). A pop-up menu

appears.

2. Click the Enable Unit Beaconing option. The check mark

disappears from the box adjacent to the option, and unit

beaconing is disabled.
