You will need:

• A Monitor connected via either DVI or VGA;
• A Keyboard (either USB or PS/2); and
• Either:
  • An Internet connection (which can access rsync.guralp.com); or

1. Ensure the NAM-mk2 is powered off.
2. Connect a monitor via either DVI or VGA, and ensure monitor is turned on.
3. Connect a keyboard to the NAM-mk2.

   1. If using DHCP, type the command:

      dhcp

   2. If using the network, but not DHCP, then add IP address and gateway:
      
      

      ip addr add 192.168.0.2/24 ip route add default via 192.168.0.1

   3. If using a USB stick, plug it in now.

8. Now enter the following command:

   reflash

9. You are prompted for a machine type. Simply press enter:

   service / # reflash ======================================================================== WARNING: This action will *ERASE* all data on the CMG-NAM *PERMANENTLY*. WARNING: Do not continue unless you are sure you want to do this. Press WARNING: ctrl-C to abort. ======================================================================== NB: if you enter "usb" (in lower case, with no quotes) as the rsync server address, then you can reflash using an attached USB pen drive. Press enter to use the default, which are usually what you want. Machine [CMG-NAM-mk2]: _

10. You are prompted for a server address:

    service / # reflash ======================================================================== WARNING: This action will *ERASE* all data on the CMG-NAM *PERMANENTLY*.
