The output power of the RU is controlled by 1 dB steps for each band and for each TX port (the controllable range is 10dB from the maximum TX power for a single carrier). When the system temperature at startup is 40 to 20 , the system reports to the EMS as a Cold Start state

(refer to RU Alarms). RF transmission is not operating and power amp is set to on for warmup. The temperature is monitored from the start of the device, and the Cold start state is released when the temperature reaches 20 and reported to the EMS. The RU supports the TX power reduction on switching to battery backup at the cell site. The TX power reduction is configured by DL Gain control (controllable range is 3 dB) for each band via M-plane message. When the power source is restored from battery backup, the RU resume normal operation before switching to battery backup automatically by DL Gain controlling from host system. In case the power source is restored after power loss, the RU resumes normal operation at the condition before power loss automatically as well as any other settings, for example, frequency and output power via M-plane control from host system. Transmission Blanking The RU supports transmission blanking by PA on/off control for each RF port via C-plane control from host system. In case of warmup status, for example, cold start, PA on is set without transmission output regardless of C-plane control from host system. Dual-band RU has a transmit power of 80 W/Port and has two transmit modes, depending on the transmit power of each band. Drain Voltage Control 1. n70 + n66: 20 W + 60 W 2. n70 + n66: 40 W + 40 W Release 1.0 Issue 1.1, May 2021 Fujitsu and Fujitsu Customer Use Only RU Hardware Feature TX Control Function 62 In order to reduce power consumption, the RU controls the drain voltage of the power amp in accordance with the transmission mode. The drain voltage is switched according to the transmission output power of each band. The transmission output power of each band is checked by the DL Gain value in the M-plane "TX-Array-Carrier"

message. When transmission carrier setting is added or changed during operation and switching of transmission mode occurs, transmission is turned off to change drain voltage, and transmission control is performed again after switching drain voltage.

power output for the LTE n66 band has been increased from 40W to 60W and an OBW addition of 25MHz for LTE n70 has been added. Therefore, Fujitsu needs a brand-new FCC ID and Limited Testing based on the FCC response on 05/14/2021:

The DB 5G RU already has FCC approval (CFD5GRUDB), however, due to a recent change, the From FCC: For the new filing, all test reports are required. For the n66 band at 60W you must perform a complete retest. For the n70 band at 40W portion you must do testing for the 25 MHz BW. For the n70 band you may include the test data for 5 MHz BW, 10 MHz BW, and 20 MHz BW from the previously certified product. The test report must clearly document what data is reused and the original FCC ID. Reports submittal and use of each report for this certification:

Nemko Report. As per the test plan and based on the FCC guidance Nemko did full testing on Band n66 and limited testing (only 25MHZ BW) for Band n70 and this is reported in Nemko radio report 443812-TRFWL (FCC Part 27). Test results for Band n70 for all the other BW (5MHZ/10MHZ and 20MHz) will be leveraged from Intertek reports since the product is identical and all testing is representative. Intertek Report(s). As described above the only usable/valid data for this new certification will be from Band n70 with 5MHz BW, 10MHz BW & 20 MHz BW from the following reports:
