point on the cable guide from where they can be fanned out and fed to the Base
station Distribution Units (BSDU’s).
! Data cables terminating at the front of the BSDU’s should be fed through the
brush gland fitted adjacent to the units and secured to the cable management bar
using tie-wraps.
! When cabling the BSPS cabinet consideration should be given to future growth
and expansion. Allowances in cable forms should be made for the removal of
equipment for maintenance, i.e., BSDU’s, Power racks etc.
! Where cables are installed but not connected to equipment they should be tied
off in such a way as to prevent damage, allow for future growth and
maintenance. Pre-terminated cables should be treated with care and should not
be laid out in vulnerable areas where they may be susceptible to damage.
! Cable crossovers should be kept to a minimum to prevent system interference
and allow easy equipment removal.
! Ensure that the cables are dressed in such a fashion that they are not exposed to
hot exhaust air, sharp edges, doors etc.
! Observe recommended minimum bend radii when installing copper cables.
Wherever a cable changes direction, ensure that it does so in a smooth curve
with a radius of at least 50mm in order to prevent damage.
! Cables shall be secured directly to cabinet cable trays with plastic cable ties.
Secure the data and power cables at regular intervals within the cabinet to the
cable management trays/trunking provided using cable ties. These ties should be
tensioned and cut using the supplied tool 1PAC10370ACK.
! Care is to be taken to ensure that cables providing connection to peripheral
equipment (e.g. PC’s) do not pose a trip hazard.
! WipLL system interface cables providing connection to a network shall be
terminated and presented to a digital distribution frame (DDF) as agreed with the
customer. Dressing of cables at the DDF shall be done to ensure a potential trip
hazard is not created.
