Troubleshooting
Failure to follow the instructions in this section can result in
component damage.
If the fan assembly LED is amber, the fan assembly must be replaced as soon
as possible.
Figure 4-10. Fan Assembly LED
See “Replacing Components” later in this chapter for important information on
how to replace this module.
Do not allow the RA4000 to operate for more than five minutes
without a working Fan Assembly in place. Operation longer than this with no
forced air cooling, especially in arrays with a full complement of drives, may
permanently damage the drives or electronics in the RA4000 and result in data
loss.
When hot-plugging the Fan Assembly, be sure to have everything ready before
you begin the procedure, which should normally take no more than one minute.
