Jump ers
Caution: Jumper configuration to be performed by qualified service personnel only.
Disconnect the AC power cord prior to accessing any component inside the rear cabinet.
Located on the backplane printed circuit board are six jumper blocks. From these jumpers system integrators can manually configure the DEU subsystem. To change the jumper setting, pull the jumper plug off its pin(s) and carefully fit in down onto the pin(s) as indicated. This allows the user to make reversible changes to the circuitry on the printed circuit board.
The jumper settings are known as “open” or “unjumpered” and “jumpered.” When unjumpering the setting remove the jumper plug from both pins and seat it over just one of the pins. This allows the jumper plug to be stored for later use.
