- The array expansion shelf must be able to slide forward out of the rack 12-15 inches to service the fans. All cabling (network, console, power, SAS) must have at least 24 inches of slack when connected to the chassis to ensure uninterrupted operation during fan replacement.
- If one fan fails, the array can still function with three healthy mid-plane fans while the replacement is installed.
Procedure
-
Remove top cover to uncover mid-plane fan.
-
From the back of the array or expansion shelf, unscrew the two green
thumb screws securing the top cover.
-
Slide the top cover to the rear of the chassis until it stops.
Note: Ensure that the power and networking cables do not interfere with the top cover.
