From TSM, it's not possible, you have to either point the TCPServeraddress to an IP or fully qualified name.
TCPS 192.168.34.52
or
TCPS tsmserver.mycompany.com
So if it's possible, it would have to be done at the networking level on the OS so that it automatically finds a route to either that IP or hostname if the other route is down.

If you are talking about 2 different IP addresses, then it is not possible.
However, if you are using multi-homed networks, meaning two or more route for a specific IP address and using load balanced NICs, then it is possible. As marclant said, all from the OS level.
Here is how this works.
TSM server and TSM clients has two or more NIC that are load balanced and terminated to different switches. The switches are VLANed such that the backup IP is seen across all switches and routers.
When a card or switch fails, data is still routed properly.
