Huawei RH2288H V3 - Verifying Cable Connections

● If you cannot identify cables using the cable labels, attach an engineering
label to each cable.
● Protect cables from burrs, heat sinks, and active accessories, which may
damage the insulation layers of cables.
● Ensure that the length of cable ties for binding cables is appropriate. Do not
connect two or more cable ties together for binding cables. After binding
cables properly, trim o the excess lengths of the cable ties and ensure that
the cuts are neat and smooth.
● Ensure that cables are properly routed, supported, or
xed within the cable
troughs inside the cabinet to prevent loose connections and cable damage.
● Coil any surplus lengths of cables and bind them to proper positions inside
the cabinet.
● Route cables straightly and bind them neatly. The bending radius of a cable
varies with the position where the cable is bent.
– If you need to bend a cable in its middle, the bending radius must be at
least twice the diameter of the cable.
– If you need to bend a cable at the output terminal of a connector, the
bending radius must be at least ve times the cable diameter, and the
cable must be bound before bending.
– Do not use cable ties at a place where the cables are bent. Otherwise, the
cables may break.
Common Cable Routing Methods
The methods of routing cables inside a cabinet are described as follows:
● Determine overhead cabling and underoor cabling for power cables based
on specic conditions of the equipment room. For example, take into
consideration the AC PDF, surge protector, and terminal block.
● Determine overhead cabling and
underoor cabling for service data cables
based on specic conditions of the equipment room.
● Place the connectors of all service data cables at the bottom of the cabinet in
order so that the connectors are
dicult to reach.
Cable Routing Rules
NO TICE
To ensure optimal heat dissipation, do not block the air exhaust vents of PSUs.

CA UTION
Before verifying cable connections, ensure that the power is o. Any incorrect or
loose connection may cause personal injury or equipment damage.
