When I connect to the switch using the serial interface, I get the username prompt but nothing I type seems to register. I've tried both Hyperterminal and SecureCRT, with no luck. Am I doing something wrong? Do I have a wrong setting on my terminal app? I'm using VT100 emulation, 8n1 with no flow control.
Use a console cable with following minimum pinout (the flat gray one with the RJ45- D9 type converter currently shipping with new P33xx switches will suffice): DB9 Console Port 1 ----------- 6 2 ----------- 3 3 ----------- 2 4 ----------- 4 5 ----------- 5 6 7 ----------- 8 8 ----------- 7 9
Obviously the speed is set to 9600
maybe stop all sessions & try to re-establish a new one. The instruction manual warns u can only run one..
Hi, it sounds like its not receiving anything from your console. your settings sounds correct for your serial comms etc.. if you can see the data coming in on the screen (ie user prompt). Check your serial cable to ensure you have actually wired it up correctly, perhaps the wire for Rx has fallen off / bad solder joint (at the network switch end), or could be the Tx end as well (at the computer end). check that all the pins look okay and aren't bent at the computer serial port, you could also try another serial port or another computer. I use Hyperterminal for many applications. You may also need to use a null modem serial cable (i dont know what you are using).

telnet to the IP address of the Cisco switch
Enter the telnet access password for the Cisco swict when requested, and then the "Enter" key.
Type "enable" at the command prompt, and then the "Enter" key.
Enter the Privileged Exec password when requested at the command prompt, and then the "Enter" key. Then enter "configuration terminal" at the command prompt, and then the "Enter" key.
Type "interface fastethernet0/1," replacing the "fastethernet0/1" with the name of an interface in which you wish to enable PoE, and then the "Enter" key. Then, while in interface configuration mode, type "power inline auto" and then the "Enter" key. Repeat this step for each interface in which PoE is required.
Type "end" at the command prompt and then the "Enter" key, copy running-config
Below is some commands to run, I don't have any power on the interface but this will show you if this is working...
SW1#sh power inline fastEthernet 0/1
Available:360(w) Used:0(w) Remaining:360(w)
Interface Admin Oper Power Device Class Max
--------- ------ ---------- ------- ------------------- ----- ----
Fa0/1 auto off 0.0 n/a n/a 15.4
Run this command to see the interface is up.....
SW1# sh interface fastEthernet 0/1 ' in protocol
FastEthernet0/1 is up, line protocol is up (connected)
SW1#sh cdp interface fastEthernet 0/1
FastEthernet0/1 is up, line protocol is up

To re-enable the Console access requires the SW2900 series to be reset to its default settings via the WEB INTERFACE

-Once the unit has successfully booted and the prompt presented
-Enter "password" (without "")
-Enter "admin" when the system prompts for User
-Press the "Enter" key when the system prompts for "Old Password" (the ADMIN password was reset by the Web Interface commands)
-Enter "" when the system prompts for the New Password (where "" is the new product ADMIN password)

SW2900 Baseline Switch - Default console access disabled following password change
From the web interface, the default user "admin" password is changed and console access is disabled Cause:
When applying the new password, by default
the service-type is set to "telnet". When applied, the default
"terminal" setting is removed thus disabling console access.
Using a Null-Modem Cable , hook up the Console port of the switch to an available COM port on a computer (cable must be able
to provide serial port communication between 2 computers).
Set up a Hyperterminal session to that COM port (e.g.: com1), with
the port settings at 9600/8/N/1/N (. When the screen comes
up blank with a blinking cursor, hit [enter] once or twice to bring up a
Alternative to 1 and 2 above, if there is a known assigned TCP/IP
address for the switch, one can telnet to that address, hit
[enter] once or twice to get the login prompt.
Default logins to try are admin/(no password) or security/security. One of those 2 should bring up the management menu.
To reset factory defaults, type SYSTEM[enter] then type
INITIALIZE[enter]. This will reset everything that has been set up on
the switch, with the exception of the TCP/IP address, if there is one.
All other previous configurations will need to be
You can type in username "3comcso" and password "RIP000". It will ask you to reinitialize the switch.
This will reset all settings including passwords.
Hi Nalinfrancis, One way you can config the LP is to log on to the serial interface and then configure an IP address to the first eth port that is available. Then connect directly to the port using a crossover cable depending on the laptop or pc that you use if it can switch put your laptop/pc on the same network that you configured on the port. Then connect via your browser to the IP address assigned to the LP. Logging with you default username and password. From there you can do all the configuration via the web interface. Regards,
Download free version of HyperTerminal for Vista : ftp://ftp.hilgraeve.com/htpe/htpe63.exe Make a new connection : connect using COM1 (depends of your configuration) 19 200 bits/sec 8 data bits No parity 1 stop bit No control of flux
And push enter twice to display a "Login:" prompt. Connect using default user/passwords : http://support.3com.com/infodeli/tools/switches/ss3/management/ug/setup.htm#13131
Make sure you're using the correct console cable...if it's not wired correctly, hyperterminal will continue to give you a blank stare no matter what you do. A great way to verify your cable is to try it on another switch that's working ok. Your hyperterminal comm settings should be 9600 baud, 8 data bits, one stop bit, no parity, and flow control disabled...assuming no one changed the default console settings on the switches.
If you are still having trouble getting a prompt from the console, you can try the following procedure, although this is only known to work on earlier versions of the Baystack switches...
Shut down the power and wait for about a minute. With hyperterminal connected...turn on the power and type "NetICs" (don't include the quotes) within 15 seconds of turning on the power. This should place you in a privileged mode and allow you to use the menu to reset the switches to factory defaults. Good luck!
