MAP 0200: POST Failure Analysis

When the switch is powered on, it performs a series of power-on self-tests

(POSTs). When POSTs complete, the switch performs an initial program load

(IPL) that loads firmware and brings the unit online. This MAP describes fault

isolation for problems that may occur during the POST/IPL process.

If an error occurs, the POST/IPL process continues in an attempt to initialize the

switch and bring it online. An event code 400 displays when the switch completes

the POST/IPL process.

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

↓ An AC power distribution problem is indicated, and analysis for the

failure is not described in this MAP. Go to “MAP 0100: Power

Distribution Analysis” on page 54. Exit MAP.

Was an event code 400 or 411 observed at the EWS Event Log or at the Edge

Switch Event Log (HAFM appliance)?

YES NO

↓ Analysis for the failure is not described in this MAP. Go to “MAP

0000: Start MAP” on page 32. Exit MAP.

Table 6 lists event codes, brief explanations of the codes, and the associated steps

that describe fault isolation procedures.
