Help installing HP 1920 48G

[TomHD]

Hi all,

 

As mentioned in a thread the other day, hardware is my weakest area of knowledge so please bare with me.

 

I have a new HP 1920 48G, have it in the rack and a PC connected. I logged into the web interface and started the wizard.

 

 

So I entered 10.166.113.25 for IPv4 address and 255.255.0.0 automatically entered for Masklen. Clicked Next then Finish, an error came up but before I could see it and the switch logged me out. Now I cannot get back into the web interface using the default IP nor the one I entered above! I have no idea what to do from here. Help is needed

 

Thanks, TomHD

I don't have any 1920 but we do have 2920, couldn't you just use the console cable and login to it, as you can physically access the switch.

 

Then you could set the IP there (or atleast check what it is).

Are you struggling to get to the switch itself, or just struggling to log in? As you have changed subnets, you need to be able to access both from your PC - you may have routing between the subnets in place to allow this - otherwise you may need to connect directly to a port on that subnet to access it. Or, use the cable.

To get the switch itself, I'm guessing the 255.255.0.0 is the issue?

 

Like I say, terrible with hardware! SO how do I get access via the console port? I have no serial ports to use on a PC/Laptop!

[Achandler]

I thought they gave you a USB to Serial cable in the box nowadays, or atleast a management cable, that looks like a network cable (usually black). You can plug that into the front of the switch then access it (see the quick guide on exactly how), we use console cables usually.

 

Otherwise jsut reset the switch, isn't there a pin push button on the front of them?

[TomHD]

Nope, console cable is RJ45 to serial and no reset buttons at all!

 

I have just found a RJ45 to USB in my cable spares box... So just plug and play? Scratch this, the RJ45 looking end isn't RJ45

Once you set the IP address to the correct manual IP address for you're network - you then need to plug the switch into you're actual network, and you should be able to connect to it from any PC on you're network.

I've got 3 of these and I had to go rooting through the WEEE pile to find a machine with a serial port and set IP/mask and password via a console cable and terminal session. The manual is suprisingly helpful!

Frankly it's just so much easier to plug them into you're network so that they automatically get a DHCP address and then can be connected by a PC of you're choice via the web interface or telnet, change the default passwords, and start setting them up. I've not used a HP serial/usb cable for set up ever, in the 10+ years I've been using Procurves!

I think I have managed to give it a static IP now. Thanks to everyone for the responses, by plugging it into the working network I was able to see the switch in DHCP and get back in to assign a static IP

 

When I look in the Web Management Platform>Network>VLAN Interface I see VLAN ID = *1 | IPv4 Address = 10.166.113.25/24 | Admin Status = Up | Method = Manual. I'm not sure what this means exactly, does the manual elaborate on this?

 

Thanks, TomHD

The manual tells you it is using you're fixed IP address that you entered and not using DHCP on the server. I believe this is what you wanted?

[TomHD]

^ Exactly what I wanted, thanks again all.
