LampSite Site Maintenance Guide

This chapter describes the RHUB maintenance items, involving the equipment room, equipment, power system, and grounding system.

3 pRRU Maintenance Items

This chapter describes the pRRU maintenance items, involving equipment and power system.

4 Powering On and Powering Off the RHUB

After the RHUB is powered on, check the indicator status. Power off the RHUB in normal or emergency mode as required.

5 Powering On and Powering Off the pRRU

After the pRRU is powered on, check the power supply voltage and indicator status. Power off the pRRU based on the power supply mode.

6 Replacing the RHUB

The RHUB is an indoor convergence unit. It converges multiple pRRUs to the BBU. Replacing the RHUB interrupts services carried on the serving cell.

About This Document

7 Replacing an Optical Module

An optical module provides a port for opto-electronic conversion. This enables the transmission between the RHUB and BBU through the optical fiber. Replacing the optical module requires removing the optical fibers. This interrupts all the services.

8 Replacing the RF Daughter Board

This section describes the procedures for replacing the RF daughter board of the pRRU. A pRRU can have two transmission ports or three transmission ports, requiring the same installation operations. This section uses the pRRU with three transmission ports as an example. Replacing an RF daughter board interrupts all the services carried on the pRRU.

9 Replacing the Wi-Fi Daughter Board

This section describes the procedures for replacing the Wi-Fi daughter board, which applies only to a pRRU with three transmission ports.Replacing an Wi-Fi daughter board interrupts all the services carried on the pRRU.

10 Replacing the pDock Mother Board

This section describes the procedure for replacing the pDock mother board. Replacing the pDock mother board of a pRRU will interrupt all services carried on the pRRU. A pDock mother board can have two transmission ports or three transmission ports, requiring the same installation operations. This section uses the pDock mother board with three transmission ports as an example.
