Overview 

This document contains step-by-step disassembly instructions for the Versa S900 chassis. The instructions are 
illustrated where necessary with images of the part that is being removed or disassembled. Furthermore, the screws 
that are removed are shown next to the image of the parts themselves. 
 
NEC reserves the right to make changes to the Versa S900 chassis without notice. 
 
 

Technician Notes 

Only technicians authorized by NEC Computers International BV should attempt to repair this equipment. All 
troubleshooting and repair procedures are detailed to allow only subassembly/module level repair. Because of the 
complexity of the individual boards and subassemblies, no one should attempt to make repairs at the component 
level or to make modifications to any printed wiring board. Improper repairs can create a safety hazard. Any 
indication of component replacement or printed wiring board modifications may void any warranty or exchange 
allowances. 
 
 

Disassembly Instructions

Reassembly Instructions 

Reassembly is the reverse of the disassembly process. Use care to ensure that all cables and screws are returned 
to their proper positions. Check that no tools or any loose parts have been left inside the chassis. Check that 
everything is properly installed and tightened.
