Chassis Replacement Instructions

Remove the Drives

IMPORTANT:  Overland recommends that you number the 
drive assemblies after removal. The assemblies must be

voids the drive warranty.

the assembly handle.

handle

 to pull the assembly out.

3.

Number the assembly

 and set it on an ESD surface.

4.

Repeat 

Steps 1–3

 for the 

remaining

 assemblies.
