RV1 and RV2 . If necessary, use the EXT-8100 Extender Board to adjust the potentiometers with the
card running in the frame.

Board Installation
Use the following steps to install the AMA-8511 in a RossGear 8000 series digital distribution frame:
1. Refer to the User Manual of the RossGear 8000 series frame, to ensure that the
frame is properly installed according to instructions.
2. Please note that heat and power distribution requirements within a frame may dictate
specific slot placement of cards. Cards with many heat-producing components
should be arranged to avoid areas of excess heat build-up, particularly in frames
using convectional cooling.
3. After selecting the desired frame installation slot, hold the AMA-8511 card by the
edges and carefully align the card edges with the slots in the frame. Then fully insert
the card into the frame until the rear connection plug is properly seated.
BNC Labels
Affix the supplied BNC label, as per the included instructions, to the BNC area on the rear of the rack
frame.
