HANDLING PRECAUTIONS FOR
STATIC-SENSITIVE DEVICES

This product is designed to protect sensitive components from
damage due to electrostatic discharge (ESD) during normal operation.
When performing installation procedures, however, take proper static
control precautions to prevent damage to equipment. If you are not
sure of the proper static control precautions, contact your nearest
sales or service representative.

Procedure

To configure the unit using internal Switchpacks S1 and S2:

1. Power down the unit and disconnect the power supply.

2. Remove the enclosure cover:

— Insert a small, flat screwdriver blade into the slots on one side of the

cover and push to free the inner latches

— Lift off the cover to expose the circuit board

3. Locate Switchpack S1.

4. Set Switch 1 on Switchpack S1 to ON to enable Switchpacks 1 and 2.

5. After you enable the switchpacks, you must set the switches to your desired

configuration.

6. Replace and secure the cover.

7. Power up the board to reset and enable the new configuration.
