One LPU and grounding kit ( Table 35 ) is required for the PSU drop cable connection to the
ODU. If the ODU is to be connected to an auxiliary device, one additional LPU and grounding
kit is required for the Aux drop cable. Order the kits from Cambium Networks (
Table 36 ).

LPU and Grounding Kit (One Kit Per End) C000065L007A
Note
LPUs are not suitable for installation on SFP copper Cat5e Ethernet interfaces. For
SFP drop cables, obtain suitable surge protectors from a specialist supplier.
SFP optical Ethernet interfaces do not require surge protectors.
LPU for GPS drop cables
When a GPS receiver is the timing reference source for PTP-SYNC (optional), an LPU must be
installed near the point at which the GPS drop cable enters the building. A single LPU from the
LPU and Grounding Kit (C000065L007A) (
Table 35 ) is suitable. Alternatively, the single LPU kit
for PTP 250/300/500 ( Figure 23 ) could be used.
