Troubleshooting Problem Solutions and Tips
11.1.2 Cooling Status
If the cooling status LED lights green, both the installed fans and the interior
temperature of the storage subsystem are OK.
11.1.2.1 Cooling status LED lights yellow
I
This indication means that a redundant fan is defective, but the temper-
ature is OK.
One of the fans is defective
I
In this case, the status LED on the fan module lights yellow (see section
“Fan LED” on page 23).
Ê Replace the fan module (see section “Installing/Removing the Fan Module”
on page 34).
V
CAUTION!
It is imperative when replacing the fan module during operation that
you take no longer than 30 seconds, since otherwise the temperature
in the storage subsystem can exceed the permissible limit values.
After the fan module has been replaced successfully, both the status LED on
the fan module and the cooling status LED must light green again.
11.1.2.2 Cooling status LED lights orange
In this case there is a cooling fault.
Ê Check whether or not all the fans have failed. In this case the status LED on
the fan module lights orange (see chapter “Fan Module” on page 33).
V
CAUTION!
The PRIMERGY S60 storage subsystem (without Remote Service
Board) switches OFF at an interior temperature of 55°C (see section
“Storage Subsystem Switches OFF” on page 75).
If the status LED on the fan module lights green or yellow, the temperature in
the device is too high although the fans (or at least one of the fans) are working.
Check whether or not the ambient temperature is too high or the air outlet on
the rear of the device is obstructed.
