Contact the next level of support. Exit MAP.

Have the customer inspect and verify that facility power is within specifications.

These specifications are:

■ One single-phase connection for each power supply.

■ Input power between 120 and 230 Vac.

■ Input current between 2 and 4 amps.

■ Input frequency between 47 and 63 Hz.

Is facility power within specifications?

YES NO

↓ Ask the customer to correct the facility power problem. When facility

power is corrected, verify switch temperature cools to within the

operational limit.

Inspect the fans. Do one or more fans appear to rotate at insufficient angular

velocity (failure pending)?

NO YES

↓ Remove and replace the affected fan (“RRP: Cooling Fan” on page 185).

After fan replacement, verify switch temperature cools to within the

operational limit.

A power supply problem is indicated. Go to “MAP 0100: Power Distribution

Analysis” on page 51.

An SBAR is not recognized by switch firmware because the firmware version is

not supported or the SBAR failed. Advise the customer of the problem and

determine the correct firmware version to download from the HAFM appliance.

Download the firmware (“Download a Firmware Version to a Switch” on

page 167). Perform the procedure described in

“Collecting Maintenance Data” on

page 151

after the download.
