AirPort Utility 6.3.1 under Yosemite OS X (10.10.4) does not support the old AirPort model that you have.
You will need....or be able to borrow for 10-15 minutes..... a Mac running Leopard OS X (10.5.x), Snow Leopard OS X (10.6.x) or a PC with AirPort Utility 5.6.1 for Windows installed on the device to be able to administer the older AirPort that you have.
