length of the Ethernet cable is 100m when operating at 100 Mbps and 70m
when operating at 1 Gbps.
7 If the MGMT port will be used for remote management, connect it to the
appropriate data equipment (use a straight Ethernet cable to connect to a
hub/switch/router). The maximum length of the Ethernet cable is 100m.
8 Connect the DC power cable to the power jack of the PIU module. If a
redundant PIU is installed, connect a DC power cable also to the second PIU
module. Connect the power cord(s) to the -48 VDC power source(s), as follows.
Connect the black wire to the 48 VDC contact of the power source.
Connect the red wire to the + (Return) contact.
Connect the ground wire to the ground.
9 For AU-ODUs that connect directly to AU-IDUs: Connect the IF cable(s)
(already connected at the other end to the AU-ODU(s)) to the proper channels
(ODU 1 to ODU 4 connectors) of the applicable AU-IDU module(s). If only a
single AU-ODU per AU-IDU is used, connect the IF cable(s) to the appropriate
ODU-1 connector(s). To avoid transmissions at undesired frequencies, verify
that the frequency and bandwidth parameters are properly configured before
connecting the IF cables.
For AU-ODU that are powered by a Power Feeder: Refer to Section 2.3.3.
CAUTION
A maximum of eight AU-ODU-HP units can be powered directly from the Base Station (via the ODU
connectors of AU-IDUs) using regular (35A) PIU(s). High-Power (58A) PIU(s) can support up to 20
AU-ODU-HP units. Additional AU-ODU-HP units should be powered by ODU Power Feeder(s).
