Switch and Jumper Settings

Overview

Several switch and jumper settings are required for proper operation of the VNA Card. The following settings are set during the system commissioning and programming and should not be changed. If replacing an existing 69266-001 T1 card or VNA card for maintenance purposes, be sure to replicate the switch and jumper setting of the card being replaced. Refer to Figure 1 for the switch and jumper locations.
