10.1 Adding Boards
Input and Output Boards
The number of input and output signals in an enclosure determines the
number of input and output boards. In an enclosure, signals are sent and
received through input or output connectors. Each board has eight
connectors.
To add an input or output board:
Warning:
To avoid ESD (Electrostatic Discharge) damage to sensitive
components, make sure you are properly grounded (see the
Caution
page
inside front cover) before handling any internal 8Y-XL materials.
1. Turn off the enclosure.
2. Remove the plate that covers the empty expansion/control slot.
Make sure you are working with the correct slot. If you put the board
in the wrong slot, signal routing is affected. The board’s location
must match the system’s configuration information (uploaded from
the configuration file). A new configuration file is sent with new
boards.
3. Attach the daughter board to the switching board.
