When two RF cabinets are installed, the routing of the power cables to the extension RF
cabinet is as follows: The power cables are routed along the right of the APM30, through
the rectangular cable hole on the right of the APM30, and then along the support at the
bottom. After led through the cable hole in the bottom middle of the RF cabinet, the power
cables are connected to the DCDUs.
For a single RF cabinet on which the APM30 is stacked, the monitoring signal cables are
routed downwards along the cable trough on the right of the APM30 (seen from the front).
After led through the round cable hole on the right of the APM30, the monitoring signal
cables are connected to the FEMA in the RF cabinet.
When two RF cabinets are installed, the signal cable between the cascaded RF cabinets is
led from one cabinet to the other through the rectangular cable hole in the middle of each
RF cabinet.
The equipotential cable is routed through the round cable holes on the left of the APM30
and RF cabinet.
The equipotential cable is routed through the rectangular cable holes on the left of the
transmission and RF cabinets.
The power cables are routed downwards along the cable trough on the right of the APM30,
through the rectangular cable hole on the right, and to the support at the bottom. After led
through the rectangular cable hole on the left of the transmission cabinet, the power cable
is connected to the DCDU. If the HTMC is stacked on an RF cabinet, the power cable is
routed upwards along the left of the cabinet.
The transmission cable is routed downwards along the cable trough on the right of the
APM30, through the rectangular cable hole on the right, and to the support at the bottom.
After led through the rectangular cable hole on the right of the transmission cabinet, the
transmission cable is connected to the transmission device. If the transmission cabinet is
stacked on an RF cabinet, the transmission cable is routed upwards along the right of the
cabinet.
