MAP 0400: Loss of HAFM Appliance or Web Browser PC

Communication

This MAP describes fault isolation of the Ethernet communication link between a

switch and the HAFM appliance, or between a switch and a web browser PC

running the EWS interface. Failure indicators include:

■ Event codes recorded at the EWS Event Log or Edge Switch Event Log.

■ At the web browser PC, A Page cannot be found, Unable to

locate the server, HTTP 404 - file not found, or other

similar message.

■ At the HAFM main window, a grey square with an exclamation mark

associated with the icon representing the switch reporting the problem.

■ At the Hardware View, a grey square at the alert panel, a No Link status

and reason at the Edge Switch Status table, and no FRUs visible for the

switch.

When the logical connection between the switch and HAFM appliance is initiated,

it may take up to five minutes for the link to activate at the HAFM main window.

This delay is normal.

Caution: Prior to servicing a product or HAFM appliance, determine the

Ethernet LAN configuration. Installation of products and servers on a public

customer intranet can complicate problem determination and fault isolation.

YES NO

↓ Fault isolation is being performed at the HAFM appliance. Go to
