 +
 +Content: ​
 +Since the 8271-712 IBM switch is in reality a 3com Superstack II 3000 
 +switch, I just put the last firmware for the 3com Superstack II 3000 on my 
 +switch and by that action, the admin account was reset. I surely can put 
 +back on an IBM firmware but since the 3com firmware a more recent, I think 
 +I will keep it.
 +
 +To update the firmware and change the ip address of the switch without the 
 +admin password;
 +
 +1- Close the switch
 +2- Connect a null modem serial cable and establish a connection
 +3- Power On the switch
 +4- When all the status led of all port a on, hit reset on the back
 +5- In the console hit "​h"​ to see the context menu

 +Content: ​
 +Ahh, well - ironically, this is the reason i asked, since I was going to 
 +suggest this. I have just upgraded a switch to this firmware, and am 
 +convinced that the 3com firmware is a must have fimrware.
 +
 +Performance of the switch has improved, the web interface seems much more 
 +responsive, and clearly, it resets passwords. The serial update utility is 
 +superceeded by a Windows GUI version which seems to work brilliantly.
 +
 +Specifically,​ the switch is marked (on the PCB) as a 3Com Superstack II 
 +1100. The information for these models is available from the 3Com website ​
 +under the 'Old Devices'​ section of the Drivers and Updates. (NOTE: The 
 +terms used arent exact, they are my best recollection) ​

 +Is the 8271-712 a 3Com Superstack II 1100 or a 3Com Superstack II 3000 ???
 +The latest firmware for the 8271-712 is 3.22. ( '99)
 +The latest firmware for the SSII 3000 is 3.23. ( '00)
 +The latest firmware for the SSII 100 is 2.29. ( '02)

 +I have the answer to everyones problem. ​ Thanks to 3COM for such an easy 
 +way to reset their switches. Anyone and their mom will be able to reset 
 +the config on these switches. ​ At least it only works with the console ​
 +port.  This works on any superstack switch from 3com, so even with the 
 +chit chat.

 +An if that don't work you can reload or update your  firmware to reset the 
 +passwords, you will need 
 +1. firmware (for a Superstack II 3000 like I have) the url is   ​http://​support.3com.com/​software/​superstack_ii_switch_3000.htm ​ ;
 +2. a null modem cable
 +3. a TFTP Server software you can download it from 3com called 3CServer ​
 +(make sure you set the TFTP folder where the firmware file is located) ​
 + 
 +Once you have all this in hand do the following.
 +1. Connect the null-modem cable, configure Hyper Terminal for windows ​
 +users to the com port you have connected, normal com setting N-8-1 none 
 +and VT100, connect to switch (login should appear if not don't worry 
 +console may be disable)
 +2. configure and start your TFTP Server ​
 +3. on the switch push the reset button 2 seconds
 +4. wait 3 seconds
 +5. push reset button again for 1 second
 +6. you should see the prompt after a few seconds at the prompt line type 
 +the following commands
 +    F  ls3k3_23.slx ​ (firmware file name) "press enter"
 +    B  IPAddress of TFTP Server "press enter"
 +After firmware update the switch will reboot and the passwods will fall 
 +back to factory default.  ​

 +Hi !
 +
 +This is an impossible solution for my problem ...
 +
 +I?ve an 3com Superstack II 9300 2-LX/10-SX (3C93011) SWITCH.
 +
 +My Problem is: I could not login to reconfigure. My pal is walk out around ​
 +the world and the 3com-support is over, because the machine was bought ​
 +from 2001, and it?s to old since registration (just 
 +2-year-free-support-help).
 +They gave me the offer to pay lot of money for help me here. - No thanks ! 
 +I haven?t !
 +
 +Here are all my tried backdoors w/o effect (used serial-console):​
 +
 +adm/(none)
 +admin/​synnet
 +admin/admin
 +admin/​(blank)
 +admin/​nopass
 +debug/​synnet
 +write/​synnet
 +
 +... always "​incorrect password"​ !
 +--------------
 +and:
 +
 +root/​(blank)
 +root/​manger ​
 +security/​(blank)
 +security/​security
 +manager/​manager
 +recover/​recover
 +tech/tech
 +monitor/​monitor
 +3comcso/​RIP000
 +force/force
 +
 +... always ".. is not a valid access level"
 +
 +and here is NO reset-button on my machine ...
 +
 +Maybe anyone got a quick idea ?! The delivered handbooks (the 
 +customer+admin handbooks) have no details for this case...
 +
 +Does anyone have any idea or answer ?!

 +Been here done this - LOL  The firmware update (posted by dljones) ​
 +will/does work.  It's the only reliable way to get the job done that I'​m ​
 +aware of.  3COM also has a utility to push (ok - that's not really a 
 +strong enough word - SHOVE is more descriptive) a new f/w version onto the 
 +switch (actually 3300s are all I have ever used it with). You know - 
 +"​Ensure power is not disrupted during file transfer"​ about 20 seconds ​
 +before it goes completely dark and your stuck? I can't think of the name 
 +of the utility, just email me if you need the name and I can look it up.

 +Cheers for the info on the firmware loading. I have done this twice and 
 +loaded to different versions of my linkswitch 1000 firmware, but I still 
 +can't login. I have a thought though. when you type in the user you can 
 +see what you type. When you put in the password normally you get the stars 
 +that apper showing how many letters you have typed this dosn't happen. ​
 +
 +Any thoughts

 +Well I was trying all the passwords etc from the manual and those I have 
 +found online. For some reason the only way I could get the unit to reset 
 +was to load the oldest firmware and then a new one?
 +
 +Thanks all as I have now got into the switch, and yes in the end admin and 
 +"​blank"​ password got me in.

 +Thanks to DLJONES - but just another tip while you do his steps to waiting ​
 +the three seconds, If you actually look at the face of your Superstack II 
 +3000 after you press the reset button for 2 seconds, watch the Management ​
 +link light, wait till it flashes 3 times, then press the reset button ​
 +again for 1 second. ​ I had a lot of trouble getting the prompt to come up 
 +to type the flash file name untill I discovered that... I must have been 
 +counting too fast for the three seconds, lol.  Thanks a million for this 
 +tip.  It worked great for me again for the 3com SuperStack II 3000.

 +HELP!
 +
 +We just bought a Super Stack 1000.  I was able to RIP0000 at the upgrade ​
 +screen and get access to the manager account. ​ I need admin though.
 +
 +I'm doing everything through the serial.
 +The 3comcso/​RIP000 (mentioned above) just gives me an invalid log in.
 +
 +I would love to try "​tftping"​ a newer version of firmware (mentioned ​
 +above), but 3com has discontinued it.  I tried it with newer versions of 
 +firmware and it didn't work.

 +Download upgrades for SSII 1000 from http://​www.3com.com/​products/​en_US/​resul...
 +
 +This worked for me....
 +I first loaded the oldest ls1k2_00 and after that ls1k3_21.
 +When done admin/blank works.

 +
 +I have a SSII Desktop Switch (3C16902). ​ admin/blank does not get me 
 +in.  using the reset button, I got to the prompt. ​ I started a TFTP server ​
 +session on a remote machine, set the ip and file info correctly for the 
 +upgrades, but get an update status id of 8 (load server not responding) ​
 +when trying to do the upgrade with the "​b"​ command. ​ again, all of this is 
 +through the console port.  I have what I believe to be the correct ​
 +firmware from ftp.3com.com. I assume I have a settings problem w/ the gateway / IP info.  My 
 +question is: is my computer connected to the console port the gateway for 
 +the switch? ​ Or do I use the same gateway settings that my computer has to 
 +my router? ​ Technically the switch is not connected directly to my router, ​
 +but is rather going through my computer to the router. Any other advice or 
 +details on getting successfully connected to the TFTP server?
 +
 +
 +
 +
 +saabstory (TechnicalUser)
 +Oct 13, 2003
 +
 +
 +
 +Solved the Status 8 errors. ​ The switch needs to be MANAGED via the 
 +console port, but any data transferred (TFTP in this case) needs to be 
 +done over one of the ethernet ports. ​ I read somewhere that, to be safe, 
 +don't use the module port(s), but stick to one of the 24 default ​
 +ports. ​ Now when attempting the TFTP, I instead am getting Status 10 
 +errors (record length mismatch).
 +
 +This must be due to me having the incorrect files. ​ As a clarification ​
 +from those that have successfully upgraded, should the upgrade files be 
 +"​.exe"​ executables? ​ I noticed that someone was upgrading with a "​.slx" ​
 +file.  The only files at 3com for my switch are executables.  ​
 +
 +Again, this is a SSII Desktop Switch (3C16902), and the files available ​
 +are: dt3_10.exe, dt3_21.exe, etc.  Any other input from those that have 
 +successfully upgraded?

 +
 +Hey Guys,
 +
 +Some great info here, but I am in the same boat as nshank.
 +
 +I have tried various versions of the bios, but I can't seem to make the 
 +bios loader console react to the RIP000 or RIP0000 command prior to the b 
 +command.
 +
 +The R in RIP is interpreted as reset serial port and it immediately gets 
 +stuck with the y/n prompt for that with any response resulting in a 
 +restart of the switch with no change in password status.
 +
 +Worker99 if you are out there - what prom version does the bios loader ​
 +console have for yours ? Mine is 2.10 What is yours as well nshank ?
 +
 +
 +Thanks in advance guys.

 +AT the same point try RIP 000 or RIP 0000, I'm sorry I haven'​t worked on 
 +these for sometime. But if I remeber correctly RIP 000 should work.
 +
 +For switches 1000/1100 - same method
 +switches 3300/hub 24 etc - 3comcso RIP000
 +switc 9300/3900 - admin/​lanplex

 +As soon as I entered ​
 +RIP 0000
 +at the bios boot loader I could tell it was going to be different, no 
 +message that is standard if you type r as the first character. I then 
 +typed b for the load, after reboot, admin/<​nothing>​ got me right in. I 
 +could also tell at that point it had worked before logging in since the 
 +login screen had the name of the switch that had been programmed, and that

 +===== Switch reset - data gathering algorithm =====
 +
 +From IBM GI1956:-
 +
 +<​code>​
 +Important: Follow this procedure carefully. ​ Failure to do so can cause permanent damage to switch hardware.
 +
 +1. Set up the switch debugger:
 +
 +    a. Attach a PC to the serial port of the switch that has reset.
 +    b. Set up the terminal emulator to log the screen to a file.
 +    c. From the switch console, ​ enter the switch debugger by  pressing Ctrl-t. ​ Enter the switch ​  ​password at the prompt if  a password ​ is used on the switch. ​ You must  press Ctrl-t ​ from a screen ​ other than the sign-on screen.
 +    d. At the "​eps>"​ prompt, ​ enter one of the following commands:
 +            perf 40  (if you are using 8272 code version 2.3.1 or earlier)
 +            extmsgs on   (if you are using 8272 code version 2.3.2 or higher)
 +
 +        Note: Either of these  commands will enable extended ​ messaging. ​ The difference between the two is that  "​extmsgs on" enables extended messaging indefinitely; ​  when you are finished, enter   ​extmsgs off  to turn it off.
 +
 +       
 +2. Allow the emulator to continue to log to a file so that all messages are captured. ​ Allow the eps> ​ debugger screen ​ to remain on the console ​ the  until the switch resets.
 +
 +3.  If you need to return to the main menu:
 +
 +    a. Type cons  to return ​ to the main menu.
 +    b. Use  the menus as needed.
 +    c. Press Ctrl-t to return ​ to the debugger screen, remaining there  until the switch resets.
 +
 + 
 +4.  After the switch resets, stop the screen capture on the emulator. ​ Send captured data to IBM Support personnel.
 +
 +Note: If you are  using code version 2.3.2 or higher, go  to the debugger screen ​ after the box resets and type extmsgs off at the eps> ​ prompt to set extended messaging off.
