Title: DECbrouter90: Upgrading the software via tftp: older (2 Mb DRAM) models.

Product: DECbrouter90 V9.14

Question: What are the commands to upgrade my older model DECbrouter90's 
software to the latest version of 9.14(x) software?

Solution:


  This assumes that you have obtained the latest 9.14 software from your 
Digital support organization, and the image is loaded on a tftp server system 
(unix, VMS/UCX, etc.). The following assumes that the software is loaded from a
tftp server over the ethernet port; to load over a WAN (serial) port, see the
DECbrouter90 tech tip which discusses loading the software over a WAN port.

  Also, if you have the later model DECbrouter90 with 4.14(8) Bootrom code, the
upgrade process is greatly simplified via the "Flash-Load helper" software.
With the later Bootrom code, you simple enter the "copy tftp flash" command at
the enabled prompt. See the "Flash Load helper" Tech Tip for full Details.
  
To load the Brut system image into flash over tftp:

1) Connect the console of the router to a terminal.  Connect the Ethernet port
to the LAN segment with the tftp server on it.

2) Boot up the router, log in, and enter enabled mode.  The enabled mode prompt 
ends in # (for example, "Router#"). 

3) Type "config term".  Type "config-register 0x101".  Type Ctrl-Z <RETURN>.
Putting a value of 101 (hex) instructs the router to go into bootstrap mode 
when you reboot it; the router must be in bootstrap mode in order to load the 
flash.

4) Type "reload", and press <RETURN> at the "Confirm?" prompt.
This reboots the router.

5) The router should now be in bootstrap mode. Hit return; you should get a 
prompt that ends in "(boot)>".

6) Type "enable" and your enable password.

7) Type "copy tftp flash".

8) Give it the address of your tftp server, in IP format (for example 
16.123.96.47).

9) Give it the name of the file on the tftp server: for example, 
"/var/kits/igs-bfpx.914-12".

10) Confirm the load and the flash erase by twice pressing <RETURN> at the
"Confirm?" prompt.

11) Successful loading will be indicated by '!' characters.  Timeouts are
indicated by '.'.  If you get several timeouts, your IP address may be wrong,
or there may not be IP connectivity to the tftp server. Also, incorrect file
protection on the tftp server can cause this problem.

12) Once loaded, the router will verify and print out "successful load" or
indicate failure. 

13) Type "config term".  Type "config-register 0x102".  Type Ctrl-Z <RETURN>.
This instructs the router to boot the new flash code. 

14) Type "reload", and press <RETURN> at the "Confirm?" prompt.

15) The router will reboot, load the flash, and start running the new code.
