A failed Cooling Unit on the ASUS DS300f G2 or DS300j G2 can be hot swapped if the other cooling unit is
functioning properly (indicated by a green Fan Status LED). Follow the instructions below to replace a problem
Cooling Unit.
Important
In the event of a Cooling Unit failure, DO NOT remove the failed unit until there is a replacement
available and on hand. A single functioning Cooling Unit is adequate for cooling the system as
long as the failed Cooling Unit remains in place. Removing the failed unit without replacing it will
adversely affect airflow within the enclosure resulting in critical overheating and shutdown of the
enclosure.

o reMove the ooling nit
1. Check the Fan Status LED, a red LED indicates the fan has failed and needs to be replaced, an amber LED
indicates a problem.
2. Use a No. 1 Phillips screwdriver to turn each set screw counter-clockwise to loosen them. The screws remain
attached to the Cooling Unit so they will not be lost.
3. Pull the detached Cooling Unit out of the subsystem enclosure. You can grasp the posts that house the set
screws initially to move the unit out.

enclosure.

4. Check the Fan Status LED on the Cooling Unit to make sure it is green (functioning properly).
