From your scenario what i guess is the two 5500's (A&B) are connected to each other also. Thats why the link between B&4500 is remaining down due to STP ( to avoid Network loop).
Please correct me if I am wrong.

What is the status of the link connecting 4500 to 5500 B when 500A is active and when 5500A is down .

If you are running STP i will suggest you to wait for 2 minutes after 5500A goes down and STP will be recalculated and the link connecting to 5500B will become active and then the route will also become active.

Best regards

If you are creating only Layer 2 VLANs on the switch , you wont be able to ping the servers and Routers as they are in default VLAN1.
you can do the below steps
1. Create sub interfaces on the router LAN interface
2. Provide a new ip range to the new sub interface
3. Make the switch port connecting router as trunk, so that it will carry both the VLAN info
4. on your Labtop/PC give the IP address in the newly defined range
5. Make your switch port to be in the new VLAN

This will work , if you wont be able to configure the above settings, let me know i will give you the detailed config

The primary connection method for those switches would be serial connection. In the box there should have been a DB9 serial to RJ45 cable. Hyperterminal default settings would allow you to connect.

if it allows telnet sessions, you would go to a command prompt and type:
telnet (or whatever the IP address of the switch is.)

I don't know anything about these units, nor do I have time to source any docs for you, but maybe you can try connecting a PC directly to the port your patch panel is connecting the the switch from, you can at least see if that port is working.
My next and only other suggestion is to invest in a "LAN cable tester". In my area, you can find cheap ones for U$20.
The tester will allow you to check connectivity between any two ports, and allows you to test both patch links and individual CAT5/6 cables.
Good luck!
