Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.

1 Changes in RRU Hardware Maintenance Guide

This chapter describes the changes in RRU Hardware Maintenance Guide.

2 Preventative Maintenance Items for an RRU

Preventative maintenance improves the reliability of the RRU. You are advised to perform scheduled maintenance yearly.

3 Powering On and Off an RRU

After an RRU is powered on, check the status of RRU indicators and voltage. Before the RRU is powered off, follow the normal power-off or emergent power-off procedure as required.

4 Replacing an RRU

This chapter describes the procedures and precautions for replacing a common RRU, replacing a blade RRU, and replacing a non-blade RRU with a blade RRU by reusing mounting kits. Replacing an RRU interrupts all the services carried by the RRU and causes alarms.

5 Replacing an Optical Module

An optical module implements optical-electrical conversion, enabling optical transmission between an RRU and other devices. You must disconnect optical fibers from an optical module before replacing the optical module. Disconnecting the optical fibers interrupts the transmission of CPRI signals.

6 Adding RRUs

This chapter describes the procedure and precautions for adding RRUs with different exteriors on a pole.

3 Powering On and Off an RRU

About This Chapter

After an RRU is powered on, check the status of RRU indicators and voltage. Before the RRU is powered off, follow the normal power-off or emergent power-off procedure as required.

3.1 Powering On an RRU

This section describes how to power on an RRU. Observe the indicators on the RRU to check the running status.

3.2 Powering Off an RRU

An RRU can be powered off in two ways: normal power-off and emergency power-off. You need to perform a normal power-off in scenarios such as an equipment swap or foreseeable regional blackout, and you need to perform an emergency power-off in emergencies such as a fire, smoke, or water damage in the equipment room.

3.1 Powering On an RRU

This section describes how to power on an RRU. Observe the indicators on the RRU to check the running status.

Prerequisites



The RRU hardware is installed and RRU cable connections are secure.



The input voltage of a DC RRU ranges from -36 V DC to -57 V DC.



The input voltage of an AC RRU ranges from 100 V AC to 240 V AC.

Context

After unpacking an RRU, you must power on it within 24 hours. If you power off the RRU for maintenance, you must restore power to the RRU within 24 hours.
