LPOD C-, X-, or Ku-Band Outdoor Amplifier / Block Up Converter (BUC) MN-LPOD

Serial-based Remote Product Management Revision 10

5–3

• I2C internal bus communications fault.

• Thermal Shutdown – A temperature fault is indicated if the unit is +>90°C. This creates a summary fault and will cause the unit to

mute itself and switch to the back-up unit (if in a redundant system). However, the 10V supply to the FET transistors will remain on

until the unit reaches the thermal shutdown temperature of ≥ >95°C. For protection reasons, the unit will shut down the 10V supply

to the power transistors at temperatures >95°C.

• Firmware checksum error at power up.

• FPGA done indicator error at power up.

• *Block Up Converter (BUC) unlocked.

• Redundant waveguide switch position fault (applies to redundant mode operation only).

• Redundant inter-unit link fault (applies to redundant mode operation only).

• Low Noise Block Down Converter (LNB) current over limit.

The following parameters can be user defined to report an alarm condition, a fault condition, or the parameter can be ignored

completely by masking it:

• RF amplifier low output power (user adjustable value).

• Internal reference oscillator unlocked.

• *LNB current outside specified window.

• *LNB voltage out of tolerance.

*If this parameter generates a fault condition, the RF output will be muted.
