NIX Quick Installation Guide
Installing SFP Module 1. Wear an ESD-preventive wrist strap before SFP module
installation. 2. Find the send (TX) and receive (RX) markings that iden-
tify the top side of the SFP transceiver module. 3. Position the SFP transceiver module in front of the
socket opening.
Please refer to the antenna and ODU installation guide for installation instruc-tions of antenna and ODU.
NOTE: Dont switch on the power until all the cables are installed properly.
For the specific operating frequency of the hop, arrange to enable the RSL to become variable within an al-lowable range, correlate the data in the lookup table against the RSSI reading along all points of the RSL range. The antenna pair is identified when measured RSSI level matches against the corresponding RSL values
The above figure represents the RSSI level as the antenna is being brought into alignment. Location of the optimal signal strength should be at the maxi-mum of its RSSI profile.

1. Go to Configuration > Switch > PTP. 2. Cl ick Add New PTP Clock , and then set up Device Type as E2e Transp . 3. Configure 2 Step Flag . True refers to xxxx, False refers to xxxx. 4. Configure Protocol . Ethernet refers to two layer mult icast , IPV4 Mult i refers to
three layer mult icast, IPV4 Uni means three layer unicast . 5. Cl ick Save to accept the conf igurat ion. 6. Check the port to which the Synch Ethernet connect and port 9, then c l ick Save . 7. Set up PTP Master Enable as True , then c l ick Save .
Go to Configuration > Switch > SyncE. I f the Synch Ethernet funct ion is not required, uncheck the c lock port .
I f the Synch Ethernet funct ion is required, f i rst ly ident i fy the port to which the Synch Ethernet connect for upstream equipment, then check the desired port in both Port Configuration ( Configuration > Switch > Port) window and SyncE Configuration window.
Check the port 9 in SyncE Configuration window for downstream equipment.

Go to Configuration > MRU > IDU IP to set up the IP address for both s ides.
NOTE: After the system configuration above f inished, reboot the equipments for the changes to take effect.
