5.2 Powering Off the pRRU
A pRRU 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.
Procedure
l
Normal power-off
NOTICE
Powering off the pRRU interrupts services, and therefore perform associated operations
before a power-off.
–
If the pRRU is powered in PoE mode, remove the Ethernet cable.
–
If the pRRU is powered by an AC/DC adapter, disconnect the power cable of the AC/
DC adapter.
l
Emergency power-off
1.
Turn off the switch of the external power device.
