Factory Reset Foundry FWS24 without Console or Telnet Access

I just purchased 4 used Foundry Networks FWS24 switches.

They appear to be configured to disable console access, and restrict telnet access.  I've attempted to packet sniff any information I can in hopes to get an IP address capable of accessing the device.

Unfortunately, I have not had luck with that.

I've got a request out to the guy who sold them to me, but he has yet to respond.

I was hoping that one of the Experts here had a suggestion on how to Factory Reset the unit without the use of the console or telnet.

I think console access cant be disabled... Are you sure the console port is working ?
Did you tried different speeds (115200 etc)?

I've tried 9600 with 8 Databits, No Parity, 1 Stop Bit and Flow Control set to None.

The pin out on the cable is what it should be for communicating with this device (Null modem cable).

I'll try different speeds.

I've tried several different speeds.  No joy.

I found the settings that I'm using in a manual for a different Foundry product that was linked to by another Expert in a different question.

Any other ideas?  Is there a physical way to factory reset the device?

Can you try a cisco cable (the blue one) ?
You should at least get an error message or authentication failure message...

Unfortunately, I do not have a Cisco console cable at my disposal.   Also, the Foundry switch has DB9 for it's console port.

I'm getting absolutely no response from the console port.

I've managed to get a response from the Telnet. I figured out the switch's IP address from broadcast packets. When I try to connect to the switch via Telnet, I get the error message:  "You are not authorized to telnet to this box! Bye."  (and then the session dies)

In the manual for the Foundry EdgeIron that I have, it says the console port pin-out (on a DB9 is):


Switchs 9-Pin                         Null Modem PCs 9-Pin 

Serial Port                            DTE Port
 

2 RXD   <---------  TXD  ------------  3 TXD

3 TXD   ----------- RXD  ----------->  2 RXD

5 SGND  ----------- SGND ------------  5 SGND

I have heard back from the seller of the switches and he used a straight-through serial cable (not a null-modem one). I have tried that and it works.

ampranti: Thanks for your help.

Let me clarify:  The Cisco cable is the same thing as a straight-through serial cable. This switch just happens to have DB9 connectors on both sides, so it's easier to use a straight-through serial cable than get adapters for the Cisco cable.

ampranti was right on the money.

Straight-through serial cable (or Cisco cable) worked like a charm.  Thanks!
