It also describes the procedures for replacing components and modules. Product Version The following table lists the product version related to this document. Product Name Product Version RRU3908 V2 (hereinafter referred to as RRU3908) SRAN V100R003 eRAN V100R002C00 Intended Audience This document is intended for: lSystem engineers lSite maintainers Organization 1 Changes in the RRU3908 V2 Hardware Maintenance Guide This chapter describes the changes in the RRU3908 V2 Hardware Maintenance Guide. 2 Maintenance Items for the RRU The maintenance items for the RRU are equipment surface, equipment cleanliness, and LEDs. 3 Powering On and Powering Off the RRU RRU3908 V2 Hardware Maintenance GuideAbout This Document Issue 01 (2010-04-10)Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 1 This describes how to power on and power off the RRU. When powering on the RRU, you should check the power supply voltage of the RRU and the status of the LEDs on the RRU. When powering off the RRU, you can perform normal power-off or emergency power-off operation based on field requirements. 4 Replacing the RRU The RRU, a remote radio unit, forms a distributed BTS with the BBU. 5 Replacing the Optical Module The optical module implements optical-electrical conversion, thus enabling optical transmission between the RRU and other devices. You need to remove the optical cable before replacing the optical module. Replacing the optical cable disrupts the transmission of CPRI signals.
