Tee switch position while redundancy mode is enabled, a mode error will result.

Table A-1 Notes:
This table applies to LPOD 1:1 Redundancy System operation when the
Redundancy State is set to Tx+Rx (ESW=2).
The operational settings in this table – i.e., "0-7 (for the OFM command), and
"0/1" or "0/1-4" for the Online Unit entries, and "0" or "1" for the Offline Unit
entries – conform to the "Description of Arguments" format for remote
command and query operations as they are tabulated in Chapter 5. SERIAL
INTERFACE OPERATION.
The available operational settings for the Online Unit or Offline Unit serial
remote commands are as follows:
• AMP=0 (the Rx power amplifier is turned OFF), or 1 (the Rx power
amplifier is turned ON)
• MUT=0 (disabled, i.e., the Tx is NOT MUTED), or 1 (enabled, i.e., the Tx is
MUTED – no data is transmitted). Note that, in the Online Unit, the Tx
Mute setting (MUT) drives that unit's LNB Bias Tee setting (SBT) – if
MUT=0, then SBT=1; if MUT=1, then SBT=0.
• AUX=0 (disabled, meaning that the Auxiliary Mute Mode is turned OFF, or
NOT MUTED), or 1 (enabled, i.e., the Auxiliary Mute Mode is turned ON,
or MUTED)
• SBT=0 (LNB Bias Tee in Off State, i.e., MUTED – no data is received), or 1
(LNB Bias Tee is in Through State, i.e., NOT MUTED). Note that, in the
