Connectors
RESET Pushbutton – Depressing the RESET pushbutton causes a
partial reset of the CPU and a reset of all board devices. The GLI2 is
placed in the OOS_ROM state
MMI Connector – The RS–232MMI port connector is intended to be
used primarily in the development or factory environment but may be
used in the field for debug/maintenance purposes.
LAN Connectors (A & B) – The two 10BASE2 Ethernet circuit board
mounted BNC connectors are located on the bottom front edge of the
GLI2; one for each LAN interface, A & B. Ethernet cabling is connected
to tee connectors fastened to these BNC connectors.
