NETGEAR ReadyNAS OS 6 Rack-Mount Storage Systems 
Access the Inside of the Storage System
You must access the inside of the system to replace a fan or on-board battery.
WARNING:
Ensure that the chassis cover is in place when the system is 
operating to allow proper cooling. If you do not strictly follow this 
practice, out-of-warranty damage to the system can occur.
To access the inside of a 2120:
1.
If your system is mounted in a rack, grasp the two handles on either side and pull the 
system straight out until it locks.
The system is locked when you hear a click sound. 
2.
Remove the four screws holding the top cover in place.
3.
Slide the top cover back.
