LampSite

Site Maintenance Guide About This Document

Issue 02 (2014-05-27) Huawei Proprietary and Confidential

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.

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.
