Password disable Jumper

Our server occasionally does not accept our service admin password.  Recently it required two days of round and round to gain access.  Understanding the jumper defied as item 21 in Jumpers and connectors is not much help because the instruction is to change the jumper from pins 2 and 4 to pins 4 and 6.

Unfortunately there are already TWO pincaps on that item and, we have no pinout for the pin base. . . . .
