F flashing in display of 3Com 5500 Switch.

I have a 3Con 5500 Switch that has an F flashing in display panel and whan I go to the web interface they are a red line around the AC plug icon. Normallly this line is green. The switch is working fine.

What is this telling me?  See attachment.

Do you have redundant power adapter on it?

I have found this in getting started guide:

Green flashing ‘f’ There has been a fan failure.

"A fan failure warning message is received
Your Switch has a fan monitoring system that will generate fan failure
warning messages. Fan failure could potentially reduce the lifetime of the
Switch. The monitoring system polls the fan status at periodic intervals
while the unit is powered up.
If one fan has failed in the Switch, a warning message will be generated
in the following ways:
¦ Unit LED — the seven segment display will show a green flashing ‘f’.
¦ RMON Trap — if configured, an RMON trap is generated and sent to
the management workstation.
¦ Command Line Interface — an indication of a general hardware
failure is provided through the Top level menu displayed when logging
on to the CLI. For more detailed information about the failure select
the display logbuffer command.
¦ Web interface — an indication of fan failure is provided through the
Device Summary table for the specific unit. In addition all Summary
tables turn red to indicate the fan failure."

I had read this in the manual, but the web interface show the fans as being ok. I have phyiacally checked the fans and they seem ok.  Do they make a power adapter for the 5500?
What do you mean with "Do they make a power adapter for the 5500?"

What is the redundant power adapter you are talking about? The 5500 that we use has a AC power supply. I was assuming that RDA was an external power supply that may work on the 5500.

Actually you have helped me. I am sorry for not bring more through with my issues. I wasn't really sure how to relate my issue in technical terms.

But in our discussion I have discovered that the power unit is field replaceable and is under a life time warranty. HP has already shipped my replacements.

Thanks.
Please let me know if replacing the power unit will solve the flashing F.
Thanks.
