Possible Cause
Fans are not functioning
properly.
Possible Cause
Hot-plug fans are not
working properly.
Hot-plug fan errors are
occurring.
Hot-plug fan requirements
are not being met.
Possible Solution
Be sure that all fans are properly seated
and working.
Replace any required nonfunctioning
fans and restart the server. Refer to
your server-specific user documentation
for specifications on fan requirements.
Be sure that all fan slots have fans or
blanks installed. Refer to your server-
specific user documentation for
requirements.
Possible Solution
Check the LEDs. Refer to your server-
specific user documentation.
If the system powers up, generates two
long beeps and two short beeps (if your
server has speakers), displays
1611-Fan failure detected
and then powers down, check whether
all required fans are installed and
installed properly. When the power
comes on, the green LED on the top of
the fan assembly comes on and stays
on. An amber fan LED indicates a fan
failure. If a fan has failed, replace the
fan.
Refer to your server-specific user
documentation for fan requirements.
