■ No status symbol indicates that the switch is operational.

■ A yellow triangle indicates that the switch is operating in degraded mode.

■ A red diamond indicates that the switch is not operational.

■ A grey square with yellow exclamation mark indicates that the status of the

switch is unknown.

Is a grey square with yellow exclamation mark associated with the icon

representing the switch reporting the problem?

YES NO

↓ Go to step 28.

The status symbol indicates the HAFM appliance cannot communicate with the

switch because:

■ The switch-to-HAFM appliance Ethernet link failed.

■ AC power distribution in the switch failed, or AC power was disconnected.

■ The switch CTP card failed.

Continue to the next step.

Ensure the switch is connected to facility AC power. 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 54. Exit MAP.

At the front of the switch, inspect the amber ERR LED.

Is the LED illuminated?

NO YES
