Note: If supplying power to the node through the main input port, a power
inserter must be installed to terminate the RF signal.
13 Close the node housing. Refer to
To Close the Node Housing (on page 17).
Important Information Regarding Optical Power Levels
For nodes with both primary and redundant receivers installed, if the optical power
level of the primary receiver falls below -6 dBm, the forward redundancy module
(FRM) will switch to the redundant (backup) receiver.
The backup receiver will remain as the operating receiver until the primary receiver
The backup receiver will remain as the operating receiver until the primary receiver
achieves an optical power level of -6 dBm. However, the FRM will not switch to the
redundant receiver if the optical power level of the redundant receiver is below -10
dBm.
