Caution When Connecting RET Cable
Make sure to turn off the breaker connected to the RRH-P4 power of the DU
cabinet before connecting the RET cable between the antenna RET port and the
RRH-P4 RET port.
If you connect or disconnect the RET cable while the breaker is turned on, it may
cause an electric short circuit resulting in damage to the RET function.
