Handling Process

In such case it is recommended to use trans-software.  The size of this package is 250 MB and we can put it into free space of CF-card.

The Upgrade process is following:

1. Upload V600R003C00SPCa00-NE-trans.cc to all CF-cards:
cfcard:/
cfcard2:/
slave#cfcard:/
slave#cfcard2:/

Each card must contain this file.

2. Then upgrade device as usual according Upgrade Guide by commands:
 
startup system-software V600R003C00SPCa00-NE-trans.cc
startup system-software V600R003C00SPCa00-NE-trans.cc slave-board
 
Then reboot device

3. After rebooting you will have version V600R003C00SPCa00 but software file is V600R003C00SPCa00-NE-trans.cc.

4. Run commands

syn-system-software cfcard2: /V600R003C00SPCa00-NE-trans.cc
syn-system-software cfcard2: /V600R003C00SPCa00-NE-trans.cc slave-board
 
It will switch your active software package from cfcard:/ to cfcard2:/

5. After that operations delete old software package (V300R003C02B697.cc) and V600R003C00SPCa00-NE-trans.cc from cfcard:/ on both master and slave MPU by commands:
 
delete /unreserved V300R003C02B697.cc
delete /unreserved V600R003C00SPCa00-NE-trans.cc
delete /unreserved slave#cfcard:/V300R003C02B697.cc
delete /unreserved slave#cfcard:/V600R003C00SPCa00-NE-trans.cc
 
Now enough free space is available on main CF-cards of both MPUs.

*If you did not do previous step (syn-system-software) the following message will be shown:
Error: cfcard:/v600r003c00spca00-ne-trans.cc cannot be deleted, because it may be a system file.


6. Upload target version of software to cfcard:/ and slave#cfcard:/ using Gigabit Ethernet 0/0/0 interface  and implement upgrade as usual.

7. After rebooting you will have full version V600R003C00SPCa00

8. Finally delete V600R003C00SPCa00-NE-trans.cc from cfcard2:/  on both Master and Slave MPU
 
delete /unreserved cfcard2:/V600R003C00SPCa00-NE-trans.cc
delete /unreserved slave#cfcard2:/V600R003C00SPCa00-NE-trans.cc

Root Cause
None
Solution
Actually we advise to replace CF-cards by new ones whtch have larger capacity to avoid such problem in future. But trans-software can be used as solution.

If the trans-software is also too big, you must change the CFcard.
1、Power off the slave MPU and Plug out it, and Plug out the cfcard. Do not mistake CFcard and CFcard2.CFcard2 is in the top of the board, but CFcard is in the inside of the board.
2、copy the software、configuration file、license、patch e.t.then put the new software in the cfcard.
3、Plug in the MPU, after register,slave switchover,and once again for the new slave MPU.
