Replace the NBX V3000 cover and rack 
mounting brackets and reinstall the system 
in the rack.

Attach the power cord and then turn on the 
power switch. You can verify a successful 
boot operation by viewing the status lights 
on the front of the NBX V3000. See 
Figure 4.

Important Licensing Note:

Your NBX 

licenses are based on the System ID number of 
your old chassis. You should make a note of the 
System ID that appears on the labels on the front 
and the back of your old chassis. (Figure 3.) 
3Com suggests that you write the old System ID 
number on the label of the new chassis. You 

must

 use your original chassis’ System ID 

number when you order new product licenses. 
The System ID number also appears on the label 
on the disk drive assembly. (Item 5 in Figure 1.)
