Not able to connect to the web interface of the UPS LAN card

Hi

My predecessor had installed CISCO 3750 switches and implemented LACP on these core switches. From the IP address that was documented, there are 2 IP addresses that has been allocated for the UPS1 and UPS2  LAN Cards, I configured the IP addresses to Card-a and Card-b through the HyperTerminal and now both Cards successfully ping from any PC in the network.

When I browse the IP address 10.14.108.22 of Card-A through the explorer, it keeps searching waiting for 10.14.112.23 and finally it says the requested URL could not be retrieved.

When I browse the IP address 10.14.108.23 of Card-B through the explorer, it successfully opens the web console of the UPS card.

The LAN cable that comes from Card-A is connected to Port 12 of the Core switch- A
The LAN cable that comes from Card-B is connected to Port 12 of the Core switch- B

I did some tests to isolate the problem but can’t find the underlying problem as why I am not able to web interface UPS card A.

If I connect the LAN cable that comes from Card-A to port 12 of Switch-A\ Switch-B, I am not able to browse to the web interface. It keeps searching, waiting for 10.14.112.23 and finally it says the requested URL could not be retrieved.

Similarly, if I connect the LAN cable that comes from Card-B to port 12 of Switch A \Switch B I am not able to browse to the web interface successfully.

I am not sure as why I am not able to connect to the web interface of the UPS LAN Card-A . Please suggest as how to trouble shoot this issue.

I reformatted the UPS LAN Card-a and reconfigured the IP address through HyperTerminal,
No joy

Thank guys in advance

Hi,
- first, are you sure there is no other devices having the same IP address 22 and/or 23 on your LAN ?
- then, what I understand is Card A (IP = 22) not working and Card B (IP = 23) is working. And if you switch  ports from the switches it is the same, Card A is not working while B is working fine. So if that is the case I think you may have an hardware issue with card A.

What is weird here in your description is whe you say :
"When I browse the IP address 10.14.108.22 of Card-A through the explorer, it keeps searching waiting for 10.14.112.23 and finally it says the requested URL could not be retrieved."
Why are you talking about Card B's IP 10.14.108.23?

And when you say :
If I connect the LAN cable that comes from Card-A to port 12 of Switch-A\ Switch-B, I am not able to browse to the web interface. It keeps searching, waiting for 10.14.112.23 and finally it says the requested URL could not be retrieved.
Again why do you talk about IP 10.14.112.23 while it is card A with IP 22 you are trying to connect to?

Please correct me if I am wrong or correct your description.

Thanks for spotting this ! Sorry forgot to were my reading glass :)  I must have said:
"When I browse the IP address 10.14.108.22 of Card-A through the explorer, it keeps searching waiting for 10.14.108.22 and finally it says the requested URL could not be retrieved."


IP 10.14.112.23 does not come in my scope at all.

Ok no problem.
So if you ping both cards, but only card B is working, and when you switch ports it is the same, well this card A has an issue at least with its management interface.
Weird thing is that you can ping it so it is not totally out of order..
I suppose there is no precise ports or https or something else to put in the URL if it works for card B with only http://ip_of_card_B/
Try a hard reset on your card, or everything that you can do to reset it, but I don't have any other idea right now on this.

Under curiosity, I did few more things;

I completely isolated the UPS connecting through the Core switch. I setup a small unmanaged switch completely isolated from our network and connected a PC and the APC card (with same subnet) to this switch and I was able to browse to the faulty card through the web interface.

Another thing which I did was, I removed the UPS LAN card B from UPS2 and connected to UPS1 and changed the IP to 10.14.108.22 and it works. So not sure why it works when isolated from the network and connect directly to a pc  and not through the Core switch.

So Card B works, but it was card A which did not work! So did you put Card A in UPS2 to test it?
Could be because of vlan on your core switch but I don't think so if you have tested to swap ethernet port between card A and B on the core switch.

I put Card A in UPS2 and configured it to IP 10.14.108.23 and it pings and not able to access the web interface. I think I have only pinged swapping the Ethernet ports.I will double check swapping the Ethernet port and see if I can browse. I will post the results soon

I swapped the LAN cable of the working card to port 11 on Core switch-A \ port 11 on Core switch-B , it pings and able to browse web interface.

But If I swap LAN cable of the (faulty card) to port 11 on Core switch-A \ port 11 on Core switch-B , it pings and but not able to browse the web interface.
but surprised it works when isolated from our network.



I don't know how these switches are configured. Interesting thing is , I am able to ping from a PC only when the UPS LAN cards-Ethernet cable are connected to ports 11 on the core switch. If I connect to any other ports on the core they don't ping.
Please suggest what else to check.

You must have vlan ocnfigured on your core switches.
