LTE3137 impact on other features The LTE3137: Nokia AirScale RRH 4T4R B7 160 W feature is impacted by the following features: LTE112: Cell Bandwidth - 20 MHz needs to be enabled to use LTE 20 MHz carriers. LTE113: Cell Bandwidth - 15 MHz needs to be enabled to use LTE 15 MHz carriers. LTE114: Cell Bandwidth - 10 MHz needs to be enabled to use LTE 10 MHz carriers. LTE115: Cell Bandwidth - 5 MHz needs to be enabled to use LTE 5 MHz carriers. With LTE614: Distributed Site, AHHB can be used in distributed sites with up to 23 km fiber length to the system module. LTE1103: Load based Power Saving for multi-layer networksor LTE1203: Load based Power Saving with Tx path switching off need to be enabled to use PA shutdown feature. LTE2508: BTS Embedded Power Meter for Energy Efficiency Monitoring needs to be enabled to use energy metering feature. With LTE2541: Nokia CPRI RRH/RFM chaining, AHHB supports Nokia CPRI chain of up to four radio units. LTE2863: PIM Cancellation for AirScale 2.0 Radios PIM Cancellation for AirScale 2.0 Radios must be enabled if the built-in PIM cancellation mechanism is to be used. LTE3036: Micro DTX extension needs to be enabled to use Micro DTX extension. Warnings, cautions or notes related to the product WARNING! Risk of electric shock.Bef ore turning RF power on, RF ports hav e to be terminated by nominal 50Ω load (f or example, f eeder with antenna). Howev er, if these conditions are not met, the plastic caps that are deliv ered within the unused RF ports should remain in place. The plastic caps isolate RF power f rom the env ironment, and thus prov ide electric shock security in case RF power is accidentally on.
NOTICE: The RRH without f an should alway s be mounted in a v ertical orientation with connectors on the bottom side to ensure conv ection cooling.
