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.

4 Powering On and Powering Off the RHUB
About This Chapter
After the RHUB is powered on, check the indicator status. Power off the RHUB in normal or
emergency mode as required.
4.1 Powering On the RHUB
The RHUB is powered by AC input.
4.2 Powering Off the RHUB
An RHUB 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 indoor scenarios.

4.1 Powering On the RHUB
The RHUB is powered by AC input.
Prerequisites
The power cable of the RHUB is not connected to power, that is, the power plug is removed.
Context
NOTICE
The RHUB must be powered on within 7 days after it is unpacked, and the period of its power-
off state cannot exceed 7 days during maintenance.
Procedure
Step 1 Insert the power plug to power on the RHUB.
Step 2 Wait 3 to 5 minutes. Then check the status of the RUN indicator.
If the RUN Indicator Is... It Indicates that... Then...
Steady on There is power input, but the
board is faulty.
Disable the power supply,
rectify the board fault, and
then power on the RHUB
again.
Steady off There is no power input, or an
alarm about the board is
reported.
Disable the power supply and
check the power input again.
If the power input is normal,
rectify the board fault, and
then power on the RHUB
again.
1s on and 1s off The RHUB is running
properly.
End the power-on check task.
0.125s on and 0.125s off The board software is being
loaded.
If the loading is not complete
after 5 minutes, disable the
power supply and check
whether the data in the
configuration file is correct.
Rectify the fault and then
power on the RHUB again.

Procedure
lNormal power-off
NOTICE
Powering off the RHUB interrupts services, and therefore perform associated operations
before a power-off.
1. Remove the power plug to disconnect the RHUB with the external power input.
2. If the RHUB is equipped with an external power device, turn off the switch of the
external power device.
lEmergency power-off
1. Turn off the switch of the external power device.
