Chapter 9: TDM Services and Interfaces
On PTP 820F, the combo port labelled RFU3/SFP5 (SFP) and RFU3/2.5GE5 (RJ-45) can be configured as either an
RFU interface (RFU3) or an Ethernet interface (Eth3). By default, this port is an RFU interface.
To change the port's use from RFU to Ethernet or Ethernet to RFU:
1 Set the port's admin state to Down in the Interface Manager.
•
If the port is currently configured as an RFU port, it is listed as Radio: Slot 1, Port 5 in the Interface
Manager.
•
If the port is currently configured as an Ethernet port, it is listed as Ethernet: Slot 1, Port 5 in the Interface
Manager.
See Enabling the Interfaces (Interface Manager).
2 In the Radio Unit page, set the Admin status of Radio Unit: Slot 1, Port 3 to Down.
3 If there are any service points attached to the port, remove them.
4 If the port is configured as a Sync source, delete the port as a Sync source.
5 If the port belongs to any interface groups, such as LAG, remove the port from the group.
6 Select Platform > Interfaces > RFU/Ethernet. The RFU/Ethernet Interface Configuration page opens.
