Technical Information

Jumpers

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 CR8e 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 knows 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.
