3C10240 — NBX V3000 512 MB Memory Upgrade Kit 

If your NBX V3000 system will be licensed for more than 250 devices and/or more than 12 NBX Messaging 

ports, you must install the optional NBX V3000 512 MB Memory Upgrade Kit. 

CAUTION: Always wear a properly grounded anti-static strap when you remove the cover from the NBX V3000 

system and when you handle memory modules. Leave the memory module in its anti-static container until you 

are ready to install it.

To upgrade NBX V3000 memory:

1

If the system is running, shut down the NBX V3000 system software: 

a

Use the administrator login to open the NBX NetSet utility, and then click 

Operations > Reboot/Shutdown.

b

Click Shutdown, and then wait a moment for the message that verifies that it is safe to turn the 

power off. 

CAUTION: You must shut down the system software before you remove power from the 

NBX V3000 system to avoid file corruption problems.

2

Turn off the power switch on the back of the NBX V3000, and then disconnect the power cord.

3

If necessary, remove the NBX V3000 from the rack, and then remove the two rack mounting brackets 

from the NBX V3000.

4

Remove the nine screws (three from each side and three from the back) that secure the top cover of the 

NBX V3000.

5

Slide the cover slightly to the rear of the 

unit, and then lift the cover off.

6

Slide the new memory module into the 

socket. Press the memory module into the 

socket until the cutouts on the side of the 

memory module line up with the socket 

locking tabs, and then press down on the 

memory module until it locks into place. 

NOTE: To remove the memory module, slide 

both locking tabs away from the memory 

module until the module pops up, and then remove the memory module from the socket.

7

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