The connection of all power cables must be reliable and the
polarity must be correct.
� Grounding cable
Confirm whether the -48VGND, GND and PE are correctly and
reliably connected.
� Intra-cabinet and inter-cabinet cables
The clock cables, power alarm and testing cables must be cor-
rectly and reliably connected. The cable routing and tie-up
distance are correct. The cable ties must not be pointed and
overlapped.
Cabling Inspection
Cabling inspection includes the following parts:
� Each type of cable must be loose instead of tense at the bend.
� The routing must be laid according to the specified position and
the binding space must be consistent.
� The cabling must be smooth; no cable in the rack must be
crossed. And all cables outside the rack must be bound ac-
cording to different cabinets.
� The cables on the trough and cabling ladder must be tidy. All
cables must be bound and this is not allowed to damage the
external sheath.
� Required redundancy must be left for all cables. In addition,
all cable ties must be cut evenly so that there is no protruding
prick.
