The four 60mm cooling fans of the THS2085 are attached to a four-fan carrier assembly that is mounted to
front face of the main chassis just behind the front access door. The fan carrier assembly is secured to the
chassis front with quick release levers. Flip open each lever and pull the fan carrier assembly straight out
to remove. You may either replace all four fans at once with a new fan carrier assembly, or replace
individual fans as necessary. A connector on the fan carrier assembly connects each fan to the chassis’
+12V supply line.

The storage drives of the THS2085 are mounted in lockable drive carriers that are accessible behind the
systems front door. Unlock a drive carrier to start the drive removable process. Drive carrier mounted
HDDs are secured to the chassis with either a black slide catch. Slide the black HDD catch to the left to
grasp the drive carrier handle and then pull out the carrier to remove. Once the carrier is removed, you may
mount or remove the drive or drives as necessary. Reverse the procedure to re-install a drive carrier. Don’t
forget to re-lock the carrier when finished.
