I have an enterasys C2G124-48 switch that I need to set up some port mirroring on to troubleshoot some Voip issues. However I am having issues connecting to the switch through putty.

I am following the instructions in the manual here:

http://www.manualslib.com/manual/236620/Enterasys-Securestack-C2-C2g124-48p.html?page=49

And I have ensured that the com port is set up as follows in putty:

Speed: 9600 Data Bits: 8 Stop Bits: 1 Parity: None Flow Control: XON/XOFF

Putty initiates the connection, but nothing appears on the terminal and no input is accepted.

I have restarted the switch without any results.

Any idea what I am missing?

  • 1) are you sure that the console port is enabled? 2) why not connect over telnet or ssh? – EEAA Nov 04 '15 at 13:14
  • The switch was purchased used, and did not get a ip from dhcp, the only way I know to determine the ip is to connect to the console port. Any other suggestions would be appreciated. @EEAA – June Lewis Nov 04 '15 at 13:31
  • You might need a null-modem cable. – Tom O'Connor Nov 04 '15 at 13:43
  • @TomO'Connor the manual states a db9 cable. – June Lewis Nov 04 '15 at 13:44

    db9 specifies the end connectors of the cable. Null modem specifies what pinout it uses. Agreed with Tom, you need a null modem cable. – EEAA Nov 04 '15 at 13:50

    Once you do get control of the switch, I'd highly recommend giving it a static IP address, turning off telnet, and enabling ssh so you can access it remotely, without needing to connect a console cable. – EEAA Nov 04 '15 at 13:55

I got it with:

1 Null Modem DB9 Serial Cable +
1 USB Serial DB9 Adapter +
Putty 
   (9600 baud (x690 & x870 require 115200)
   no parity
   8 data bits
   1 stop bit
   XON/XOFF flow control) +

Switch Enterasys B2H124-48

I didn't get the welcome screen as said in the manual, but after type 'admin' and press 'enter' the prompt showed waiting for commands... : )

Good luck!
