Warnings and Notes
Danger: Always keep your fingers away from rotating fan blades.
Warning: The Fan module is hot-swappable. The 7705 SAR-8 operates safely for up to 4
minutes while you replace the Fan module. If a longer maintenance time is required, power
off the system to prevent over-heating conditions.
Note: In the event of a single fan failure, the remaining fans continue to run. This is sufficient
to continue to provide adequate cooling for the system, but the Fan module needs to be
replaced as soon as possible. The individual fans are not field-replaceable.
