HPA error status
• Check continuity on
ARINC buses between
HSD and antenna
subsystem
• Check continuity on
ARINC buses between
HSD and SDU
• Verify SDI is strapped
correctly (TP5B to TP5D)
• Check the external power
source is properly
connected and meets
installation requirements
• Check transmit path from
HSD output (MPC1) to the
antenna subsystem (coax
cables, splitters, relays,
etc…)
• Check the RFU TX output
(MPC1) connection to the
HSD input (TPC1)
• Check installation location
meets the RTCA/DO-160D
environmental
specifications
• Check for proper fan-tray
operation and air-cooling.
• Verify the fan-tray plug
distribution is as per the
installation requirements
