Replacing IRFU components Chapter 5: Installation
5-98
phn-2513_004v000 (Oct 2012)
Figure 111 Transceiver replacement (1+0 example)
Remove the transceiver
To remove the old transceiver, proceed as follows:
1
Power off the CMU.
2
Push the PWR button OFF for at least 3 seconds, until the PWR LED is Off.
This ensures that there are no sparks at the DC power connectors when
removing DC from the transceiver. This will also indicate to the IRFU
controller that, after installing the new transceiver, the PWR button has to be
pushed ON again. Otherwise, power will automatically turn on when DC
power is reconnected to the newly installed transmitter.
3
Disconnect both the power cable and IF cable from their respective connectors on
the IRFU.
