Surviving Digital Chaos

Being a curious sort of guy – and having an inexplicable love for tinkering with large format printers – I couldn’t pass up an offer for a really cheap, but non functioning, DesignJet T520. Can I fix it?

This is a followup post on my earlier post about chip resetting cartridges for the Canon ImagePrograf W6400 and W8400 series printers. I had the W8400D for quite a while, but haven’t used it a lot. Meanwhile I have bought a used W6400PG dirt cheap, with problematic heads and no ink.

Upgrade, downgrade or crossflash from LAP to AP style firmware on Cisco APs with serial bootloader commands.

You’ve locked yourself out of the IBM Storage Manager, have you? Or perhaps you’ve gotten yourself a used unit, but have no password for it.

Telnet to both controllers IP-addresses (or use serial console via 4pin mini DIN plug in top left corner of both controllers), and type

VxWorks login: shellUsr
Password: wy3oo&w4 (not shown as you enter it)

-> loadDebug
value = 1 = 0x1
-> setSAPassword_MT ""
ReturnCode = 0x1
value = 1 = 0x1
-> unld "Debug"
value = 0 = 0x0
-> exit

This removes the password, so you can configure through the DS Storage Manager without entering a password. Log on to controller B and follow the same steps.

No need to reboot, it should work immediately.
