I bought this switch on ebay. The seller said that he had just jused it to "split up the internet".
He had never used it as anything else then a standard switch. He didnt have the "ip" of the switch or the username/password for administrating it.
I know that you can easy log into the switch through the console despite "not knowing the password".
The switch works like a standard "non-managable" switch. All ports work, and I can connect a TP-cable from my router to the switch, and one from the switch to my computer. This works for all ports.
But im unable to reach the switch configuration. Web dosnt work, since i dont know the ip of the switch. I have tried some kommon ip's like 192.168.1.1/192.168.1.254 and 10.0.0.1/10.0.0.254 with no luck.
Normally this wouldnt be a problem, as you could connect through the serial console port (rs-232).
I can't connect through the console port.
I have a usb-to-rs232 converter that I tried without luck. This converter has worked for simular devices in the past (dreambox, other computer), but I dont get any response from the switch when using windows hyperterminal.
Thinking the serial cabel might be bad it made me try he "loopback test". By shortning pin 2-3 on the "switch side" of the cable. Now I get the characters i type in the hyperterminal, and this tells me that the this isnt a cable issue? Or could it stil be?
Bits per second: 38400
Data bits: 8
Stop bits: 1
Flow Control: None
I thought this might be because "usb-to-rs232" converters dosnt always works. I hooked up my old celeron computer, with windows XP. It has one serial communication port, but it failed to give results.
I also tried to connect the serial cable to my laptop and my old computer. This works. Characters typed on one computer appears on the other computer.
Can I use the "74-0495-01" to anything (picture below)? It was in the box with the switch, but as far as I know it isnt usable on this switch.
Is it possible to "deaktivate" the console port? That gives me a slight chance to find the "switch ip".
Is there any way to restore the switch's default configuration by shorting something inside the switch? Then i could connect to the default ip: 192.168.1.254
Is it odd that the switch works when it seems like the switch configuration side seems to be dead?
Does anyone else have some other thoughts or tips?
Here are a few things that come in my mind:
1. Check if you are using straight through DB9 - DB9 cable, not crossover
2. Try to use lower baud rates in hyperterminal, in case the speed has been changed. The common rates are 2400, 4800, 9600, 19200
3. You can install Wireshark software (http://www.wireshark.org/) on your computer and capture traffic from the interface connected to the switch. You may see the IP address of the switch in some packets, or if it's requesting an IP address by DHCP. In the second scenario, you will need to plug the switch to a network with DHCP, to allow it to pick an address and then access it by web menu/telnet
