3com Superstack II Dual Speed Hub 500 3c16611

The console ports on these hubs are by default supposed to auto detect the baud rate of the connecting machine if the Parity, Stop bits and Data size are set to the same as the swtich... whiic it looks like  you have them set properly....

Try hitting Return 2 times (or multiple times) in a row and see if you get a response... this is whats called the "wake-up" procedure on these hubs

double check for the heck of it  that you have Stop Bits = 1, Parity = none, and Data bits (Character bits) = 8

If that doesnt work try setting hyperterm to operate as a VT100 Terminal

I have setup the above information correctly including setting the terminal emulation to vt100. I have also pressed return twice and still get no prompt of any kind. Is their some way to by pass the console connection and use the ethernet ports directly?

Do you know the managemnt IP of the device?

Can you ping it?

I would say to factory reset the device if you havet done so

how do you do a factory reset?

I dont remember exactly... but now that I think about it I am pretty sure it will require console access so thats not going to work since you cant get into the console.....

This may or may not help, or you may have it already... its a PDF guide for the management module and it talks about resetting the hub....

Is the device a known working hub?  Is the management module installed properly?

I don't know the default management ip address of the device. The devices from my understanding have come from known working environments. The file you have linked up on your last post is stuff that I have been going through although confusing at times. Since I don't know the default ip address of the device. I can't even ping to it.

Sorry the file wasnt more helpful...

Are familiar with wireshark and capturing packets?
its not difficult if you arent familiar with it?

Most devices that have an IP address assigned send out whats called a gratuitous ARP.  They basically ARP for thier own ip to see if someone else claims it.   If you setup wireshark and plug your PC into a hub port and start capturing then power up the hub.... I bet you will capture the gratuitous arp and be able to glean the ip for the hub....  It will be contained in the DATA portion of the packet within wireshark...

Also if you have an idea what IP subnet (ie 192.168.10.0 / 24)the device came from you could use Look At Lan to scan the entire subnet from your pc attached to the hub and it will let you know what it finds....  You pc of course would need an ip on the same subnet (192.168.10.250)....

By the way what IP did you assign to your pc?  Have tried to change to a different ip on the same subnet in case you happen to have chosen the same ip as the hub?

I am familiar with wireshark since it is use in the cisco labs. If the switch or hub has dhcp enabled it would produce an ip address. If I assign an ip address for my local pc it would be set to the 192.168.x.x /24 subnet but another factor in setting up the ip address would be to figure out the default gateway. Also, I have heard from external sources that their is a hardware factory reset button. I don't have the hardware manual for said device. I was wondering if you by chance know of where I can find it or provide a link to where its located.

Thanks for the advice, a friend of mine found a work around solution mainly a hardware work around solution to get into the console port. It required a some adapters and a serial to usb adapter that I will be looking for in the coming days. I will keep you updated on that aspect of the switch/hub connection.
