The internal loopback test is executed automatically.
Note: The external loopback test requires a loopback cable. If a loopback cable
is not used, the external loopback test fails. A fiber loopback cable for the Model
GA620 can be constructed by connecting the Rx port to the Tx port on the same
network card. For the Model GA620T, a Category 5 loopback cable with the
following pin configuration is needed:
Pin 1 ––––––– Pin 3
Pin 2 ––––––– Pin 6
Pin 4 ––––––– Pin 7
Pin 5 ––––––– Pin 8
If the test results indicate a possible problem, try reinstalling the card or moving it to
a different slot or to a different system.Then run the DDTP tests again. If the card
still fails, contact Customer Support.
