You can replace the front fan cable in a powered-off Sun Blade 8000 Chassis.
The rear fan cable and front fan cable assemblies are field-replaceable units (FRUs). Only authorized Sun service providers should remove or install the I/O Chassis, front fan tray, rear fan cage, and the associated cable assemblies.
Before you can remove the front fan cable assembly, you must power off the system, remove all of the modules in the I/O Chassis, remove the empty I/O Chassis, and remove the front fan tray to ease access to the cable assembly. For more information, see Power Off System Before Service and the removal procedures in Replace I/O Chassis and Replace Front Fan Tray (Sun Blade 8000 Chassis).
