Are you using a cross over cable?
4.1 Method A = flash via Ethernet port of NSU
Initial setup conditions on the Laptop/PC
1. Connect the serial cable from Com port X to the maintenance port of NSU
2. Launch HyperTerminal (or similar communication) session for COM port X
3. Set the baud rate for COM port X to 38400, 8n1
4. Connect Ethernet cable (crossover cable) directly from the NIC card to the Ethernet port of NSU.
Note: If you have straight-through Ethernet cable, both NSU and PC-NIC should be connected to the network.
It is important that both NSU and PC should be in the same IP subnet; otherwise, proper gateway must be provided in the network
5. Disconnect the Fibre Cable from NSU to 3300 ICP during the re-flashing process.
Reset the NSU by hitting the reset button
Stop the “auto count-down” to set up Vxworks boot parameters
On the HyperTerminal, when you see the “Auto boot” with the count down from 3 to 1 as shown in Figure 1 during the NSU reboot, stop the “Auto boot” by hitting any keys except the space bar. Then [MC269AA Boot] prompt should appear.
Note: you have 3-second interval to stop. If you miss it, you have to reset NSU or wait for the next reset.
Change the Vxworks boot parameters
C.1 Type p at [MC269AA Boot] prompt to view your original boot parameters(see fig2 for reference)
C.2 Type c at [MC269AA Boot] prompt to change the boot parameters
C.3 Type qu at “Boot Device = flash0” line
C.4 Type enter 4 times to move the boot parameter to “Inet on ethernet ”
C.5 Type <ip address> at “inet on ethernet” (see figure 2 for reference)
C.6 Type enter 10 times to navigate to the end of boot parameters and back to [MC269AA Boot] prompt
C.7 Type p at [MC269AA Boot] prompt to confirm(see figure 2 for reference)
C.8 Once the boot parameters are confirmed
Type R at [MC269AA Boot] prompt to format the flash
C.9Reset the NSU once the format is done in less than 5 seconds
C.10top the “Auto-boot”
C.11Type Q at [MC269AA Boot] prompt to start the FTP deamon on the NSU.
Note: 1. To navigate in boot parameter, press “enter” to move to the next line if nothing is changed
Note 2. If you make mistake when typing, you can always type c at the [MC269AA Boot] prompt to go back and change because there is no backspace to allow you to correct typo.
Note 3: IP address at “inet on ethernet” should be in the format of
e.g. 192.168.10.20:ffffff00 where ffffff00 represents the subnet mask of 255.255.255.0
Note 4: All the commands at the prompt are case sensitive
FTP 4 basic files (b_loader.cmd, b_loader.o, pri_fpga.bin, vxworks) from PC into NSU
D.1 Copy the basic 4 files from Product_ Support / NSU Flash folder in 3300 ICP software CD (rel 3.2 or higher) and save these files into your NSUFlash folder.
D.2 Open the DOS session and change to the directory (i.e. NSUFlash) e.g. Type cd \nsuflash
Note: this directory that you are at must contain the basic 4 files
Note: If this is PRI, make sure that all *.dba (approximately 13 files) from IMATDB are copied into this folder.
D.3 From DOS type ftp <IP address of NSU> ?- where <ip address of NSU>=192.168.10.20 (as e.g.)
D.4 Hit Enter key twice to ignore username and password
D.5 Type binary
D.6 Type prompt
D.7 Type hash
D.8 Type mput *
Note: Ignore the first 2 warning messages on the attempt to transfer “.” And “.” directory because they represent the root directory only. This process takes more than 5 minutes. You will see transfer complete.
D.9 Type bye to exit
Change the Boot Device back to Flash for normal boot sequence
E.1 Reset the NSU
E.2 Stop the “Auto boot”
E.3.Type c at [MC269AA Boot] prompt to change the boot parameters
E.4 Type flash at “Boot Device = qu0” line
E.5 Type enter key a number times to navigate to the end of boot parameter until [MC269AA Boot] prompt appears.
E.6 Type p at [MC269AA Boot] prompt to confirm the change of boot parameter
E.5 Type @ to reboot
Connect the fibre cable back to 3300 ICP and reset the NSU. NSU will download the files from 3300 ICP and will recover in 20~30 minutes time frame.
