Routing Planning
It is recommended that cables, including E1 cables, optical fibers, and
Ethernet cables, be routed on the left side of the cabinet.
If cables are routed on the rear of a device, ensure that the cables do not
block the air vents of the device to achieve proper heat dissipation.
Before routing cables, make temporary labels and attach them to the
cables. After the cables are routed, make formal labels and attach them
to the cables as required.
Do not bundle or route outdoor cables (such as outdoor antenna feeders
and outdoor power cables) and indoor cables together in the cabinet or
cable tray.
NOTE
CAUTION
It is recommended that the power
cables of a DC device be routed on
the right side of the cabinet. To
facilitate fan module maintenance,
keep the cables away from the upper
or lower fan module insertion and
removal areas.
CAUTION
It is recommended that the power
cables of an AC device be routed on
the left side of the cabinet. To
facilitate power module maintenance,
keep the cables away from the upper
or lower power module insertion and
removal areas.
