c. Hang the device onto the pole mount bracket and tighten/adjust the screws so the
u4hm is snug but not overly tight.
4. Prepare the cable entry location (bottom).
5. Route the incoming cable(s) up the pole to the mounting location and connect to the
u4hm as follows:
u4hm Interfaces (Bottom Cover Removed)
a. Connect the WAN Ethernet cable (from the upstream ONT or PoE switch):
Feed the Ethernet cable through the right-hand cut-out in the cable entry stub (#
3 raceway above).
b. Conditional Step: If using commercial power, connect the DC power cable (from
the AC/DC adapter):
Feed the DC power cable through the ‘x’ hole in the right cable entry stub (#3 in
image above).
Connect the DC power cable to the power input jack.
c. Conditional Step: If this unit provides a wired LAN connection or a daisy-chained
link to another u4hm unit, connect the LAN Ethernet cable:
Feed the Ethernet cable through the ‘x’ hole in the left cable entry stub (#1 in
image above).
Connect the Ethernet cable to Ethernet port ‘1’ (RJ-45 interface for LAN link).
6. Once complete, route cables directly to and against the mounting pole and secure with
cable ties or other material as appropriate per local codes.
7. Seal the cable entry locations with silicone based caulk as needed.
