Managing powerconnect 2748

Hi,

I've just started in a new company where the netword switches are primarily powerconnect 2748 and Powerconnect 3424P. Now my problem is that the switches are set to managed but I have no idea what their IP addresses are, since the guy I replaced have made no documentation at all. As far as I can tell there is no console port on the switches, so how can I find out which IP addresses are being used so that I can connect to them using my browser?

Thanks in advance,

Ronnie

    3424P has a serial port.  The settings are 9600,8,none,1, no flowcontrol.

    2748 does not have a serial port.   Its default IP is 192.168.2.1.  The default Username is "admin" the default Password is (do not enter anything".  Try this and see if it works.

    If you do not care about the current config, you can just press the "Managed Mode" button and it will go to unmanaged mode.   Wait about 2 minutes for the switch to come fully up in unmanaged mode, and then press the button again.  Wait about 2 minutes and the config will be cleared and the switch will be set to the default IP and password.

    If you do care about the current configuration, you should try an IP scanning tool like "Angry IP", but then you still may have a problem figuring out the the Username and Password.

    Hi and thanks for your help so far. However scanning the network with angry ip didn't seem to find the switches, so I've looked at the advanced configuration section here

    <ADMIN NOTE: Broken link has been removed from this post by Dell> and then tried connecting using hyper terminal to the console on the 3424P using 9600,8,none,1, no flowcontrol to view the IP configuration, but no matter which command I write I get a "unrecognized command" reply:

    console> configure
    % Unrecognized command
    console> show ip interface
    % Unrecognized command
    console>

    Any idea why this is and is there somewhere that I can find a complete description of the commands to use? When connecting I didn't get prompted for a username and/or password, so could this be why my commands are unrecognized?

    Thanks again,

    Ronnie

    console> enable

    console# show ip interface

    Excellent stuff - sometimes it's so simple :). Now I get this:

     

    console> show ip interface


      Gateway IP Address        Activity status       Type  
    ----------------------- ----------------------- --------
    192.168.43.254          Active                  static  


          IP Address                 I/F             Type   
    ----------------------- ---------------------- ---------
    192.168.2.244/24        vlan 1                 Static   
    192.168.43.244/24       vlan 20                Static   
    192.168.44.244/23       vlan 10                Static   

    console#

     

    I've tried connecting to each ip address in my browser, but there are no replies and I can't ping the addresses either. Could you explaing the above info for me? I assume there are three VLAN's created, but can I use any of the ip addresses to connect to the switch?

     

    Thanks,

    Ronnie

    Usually, all ports are not members of all vlans.  So you can not ping all the IP addresses from any port.  Also, your PC needs to be on the same subnet as the vlan you are connected to and trying to access.

    Post the ourput of the following and I will tell you exactly what to do to be able to access the switch:

    console> enable

    console# show running-config
