How to connect to a 3com 3300 switch through console port unknown IP address?

I need help!  I need to reset the IP address on a 3com 3300 superstack II switch which came from another building and has a fixed ip address.  The problem is that my 3com network supervisor is not seeing this switch because it will not communicate with the main switch on the other side in the MDF.  This switch is located in an IDF closet and we swapped out the older switch because had some bad ports in it.  Has a fiber module in the back that needs to communicate with the main closet.  Can get lights on the module in the IDF, but will not communicate with the main closet.  We think it is because it has a fixed IP and need to connect to the console port to reset it.  I cannot get the 3com document to download from the internet.  Either the site has been down for 2 days, or something is wrong.   Tried going to the 3com support and cannot get any documents to download.  Anyway, I need this fixed by tomorrow morning - I have an entire side of the building down.  Anyone can help that would be appreciated.  I need a step by step instruction on the commands to type to communicate with this switch through a cable.

If you can access the console port, try logging in with user admin, blank password.  If that doesn't work try user 3comcso, password RIP000.  Post back your results.

I had the pdf manual somewhere.  Another password combo to try: security/security
I assume you don't know the 3300's current IP.  Is that correct?  You can use the recessed reset button, and it'll be 192.168.1.1, IIRC.

I have the password - this is not the issue - I just need the commands once I get the port to be recognized to reinitialize the switch.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

You can reset all the Switch units in the stack using the reset command
on the System menu.
To reset the units:
1 At the Top-level menu, enter:
system reset
The following prompt is displayed:
Are you sure you want to reset the system (y/n) [y]:
2 Enter y if you wish to proceed, or n if you want to stop the reset.


You can initialize all the Switch units in the stack using the initialize
command on the System menu.
To initialize the units:
1 At the top-level menu, enter:
system initialize
The following prompt is displayed:
Initializes the system to factory defaults and causes a
reset.
Do you wish to continue (yes,no) [no]:
2 Enter y if you wish to proceed, or n if you want to stop the initialization.
What Happens During an Initialization?
Initializing the Switch units in the stack returns them to their default
(factory) settings. The only information that does not return to its default
setting is the IP and SLIP information, which is retained to ensure that you
can continue managing the stack. You may want to initialize the stack if it
has previously been used in a different part of your network, and its
settings are incorrect for the new environment.
CAUTION: Use great care when initializing the stack — it removes all
configuration information, including password and security information.
CAUTION: When initializing the stack, network loops may occur if you
have set up port trunks, resilient links, VLANs, or the Spanning Tree

Hope this helps.

Your going to need to get into the utilty software by means of a hyperterminal session,
For that you will need to set up a system with a serial port and NULL modem cable .
Connect into the DB 9 port on the back of the switch.
For Hyperterminal accept the defaults for the setup, except for flow contol,set to none.

Once connected hit the return key once or twice till you get a login.
User name is admin ,no password .
There should be a menu item for IP configuration .You can set the IP address from there and you should be able to telnet after that.

Otherwise the default IP address is 192.1.101.1

I suspect that something is going with the switch itself.  We can get lights on the fiber module in the  closet, but it will not talk to the main closet to get external access.

Ya know the lifetime warranty ends in Oct for those things.

Matthew-Elvey-San-FranciscoCommented:
Maybe it's something obvious.
Do you have too many switches?  You can't more than two between end nodes in a Fast Ethernet network.
i.e.
node-----switch-----switch-----switch-----node won't work.

nor will
node-----switch-----switch-----desktop hub-----node

The 3com 3300 switch was going bad, we swapped it out and cannot get it to communicate with the main closet now.  We suspected that the switch was in a different building.  If I initialize the entire stack I only do that stack right?  I do not reinitialize all the switches located in other closets in the building right?

It will only reinitialize the one stack you're connected to - not any other switches in any other closets of other buildings.

If the switch is going bad, CALL 3COM!  Get a free advanced replacement unit.
These things have a LIFETIME WARRANTY.

Umm, "LIFETIME" is the product's, not the person's.  So, when a product is EOL (End of Life) so is the warranty.

pgm554Commented:
As I said before,Oct is the EOL for the lifetime warranty.
I just sent 2 back a few days ago.

manch03Author Commented:
We do have the lifetime warranty - but did they notify you that this was ending in October?
0
 
pgm554Commented:
The way it works is that the product, once it is EOL'd,has 5 years from that date for the lifetime warranty to be honered.
That product was EOL'd in 2000 or there abouts.
I was told by the support people (3Com)that Oct is the cutoff date for lifetime warranty replacement.
So get it down ASAP and start planning for replacements.I have replaced these switches at least 4 or 5 times over the past couple of years.

Ok - I finally have the null-modem serial cable and now I get nothing but a flashing cursor......  I hit enter a few times and I am still getting no log in screen.

manch03Author Commented:
I finally got connected, but it does not recognize the fiber module.  Intelligent module not present (or detected) I can't remember what it said.

Is there a security problem with this page?
I have a popup blocker, but just got a popup (a popunder) from
http://a.tribalfusion.com/, and I see that there are http://a.tribalfusion.com/ URLs in this page.

manch, did you try unplugging the unit, pulling out the module and re-inserting it?

I really urge you to call 3com and get warranty service.

Manch, based on your original question, I don't understand why you didn't split points?  You said you needed instructions to reinitialize the switch and didn't have access to the manual.  I gave you the commands you needed, but you accepted another answer?

Thanks,

Pseudo.
