For example, thread the cables throughtubes.lCables to be protected include AC power cables, transmission cables, and cables laid outunderground.lUse cable clips to secure cables outdoors.lArrange cables neatly along the routing direction and use cable clips to secure the cables.DBS3900 LampSiteInstallation Guide 9 Installing a pRRU3907Issue 06 (2015-10-30) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.149
lDetermine the positions where the clips are installed according to the actual situation.For example, 7/8" feeders are secured with clips at an interval of 1.5 m (4.92 ft) to 2 m(6.56 ft), and CPRI fiber optic cables and power cables are secured with clips at aninterval of 1 m (3.28 ft) to 1.5 m (4.92 ft). Ensure that the clips are evenly spaced and inthe same direction.lWhen fastening cables with a clip, ensure that the cables are aligned neatly and arerouted through the holes in the clip. Do not stretch the cables too tightly.lWhen using clips to secure cables, tighten the screws on the clips after all cables arearranged and laid out.Special Cabling RequirementsCabling of PGND cableslPGND cables for a base station must be connected to the same ground bar.lPGND cables must be buried in the ground or routed indoors.lThe external conductor of the coaxial wire and the shield layer of the shielded cable musthave proper electrical contact with the metal surface of the equipment which they areconnected to.lPGND cables and signal cables must be installed separately. A certain distance must bereserved between them to prevent interference from each other.lSwitches or fuses must not be installed on the PGND cables.lOther devices must not be used for electrical connections of the PGND cables.lAll the metal parts in the housing of the equipment must be reliably connected to theground terminal.9.4.2 pRRU3907 Cable ListThis section describes pRRU cables, connectors added to the pRRU cables, and installationpositions for both ends of each cable.Table 9-5 lists pRRU3907 cables.Table 9-5 List of pRRU3907 cablesCable One End The Other EndConnector Connectedto ...Connector Connected to ...EthernetCableRJ45 connector RHUB/CPRI_E0~CPRI_E7 portRJ45 connector pRRU3907/CPRI_E0~CPRI_E1 portpRRU RFJumperType N maleconnectorRF port on thepRRUDepends on theport model ofthe antennasystemAntenna system DBS3900 LampSiteInstallation Guide 9 Installing a pRRU3907Issue 06 (2015-10-30) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.150
