Chapter 5: Installation Installing a NIDU
Connecting the NIDU to the PSU, LAN and TDM cables
Caution
Always connect the NIDU to the Main PSU port of the ODU via the PSU. The TDM service
will not operate if the NIDU is connected to the Aux or SFP port of the ODU.
Caution
If the ODU port has negotiated a link at 100BASE-T, the NIDU will not send or receive TDM
data and will not bridge customer data traffic. Ensure that the Ethernet drop cable between
the ODU and the PSU, and the network cable between the PSU and the NIDU, will reliably
support operation at 1000BASE-T.
Note
Use the E1/T1 ports in ascending numeric sequence, for example: if there is one E1/T1
channel, use port 1; if are three E1/T1 channels, use ports 1, 2 and 3.
Use this procedure to connect the NIDU to the PSU, LAN and TDM transceivers.
1
Disconnect the power supply from the PSU.
2
Connect an indoor Cat5e cable from the NIDU (ODU port 3) to the PSU (LAN port):
3
Connect an indoor Cat5e cable from the NIDU (LAN port 1) to the Ethernet network terminating
equipment:
