How to Update GR2000 Firmware using ppupdate Command
----------------------------------------------------

Here's the right procedure to update GR2000 firmware using ppupdate command.
You can use the same procedure for GR4000 and GS4000 as well.



1. Copy the firmware image to gr2k's memory-card
	gr2k# ftp where.you.put.the.image
	ftp> binary
	ftp> get foo.tgz
	
	gr2k# ls foo.tgz
	foo.tgz
  
2. Move the firmware image to /primaryMC/usr/var/update/UPDATE.tgz.
   Don't forget to remove foo.tgz, since you cannot completely extract
   the firmware image due to the lack of memory-card space.

	gr2k# cp foo.tgz /primaryMC/usr/var/update/UPDATE.tgz
	gr2k# rm foo.tgz

3. Update the memory-card using 'ppupdate' command.  
   When you may have multile memory-cards (atmost four) on your gr2k,
   please update the memory-card in the following order.  It appears
   complex, but the golden rule is 'non-active one comes first'.

	gr2k# cd /usr/var/update

	 (just confirms if the firmware image is correct. it does not 
	  change anything, so please you don't have to worry anything
	  in this command)
	gr2k# ppupdate test UPDATE.tgz primary active
		or 
	      ppupdate -n UPDATE.tgz primary active
	(just displays the current and new OS version)

	 (you have to do it only when you use two memory cards on a 
	  redundant RM module)
	gr2k# ppupdate UPDATE.tgz secondary standby

	 (you have to do it only when you use two memory cards on a 
	  active RM module)
	gr2k# ppupdate UPDATE.tgz secondary active

	 (you have to do it only when you use a redundant RM module,
 	  after this command, the redundant RM module will 
	  automatically restart)
	gr2k# ppupdate UPDATE.tgz primary standby

	 (you cannot skip this, and the gr2k will automatically restart
	  after this command)
	gr2k# ppupdate UPDATE.tgz primary active

4.  Wait a moment until your gr2k boots.
