Installing and Routing Power Cables
-
Upward Cabling (TN81PDU)
M8 grounding bolt
To office power supply (4×63A)
PGND cable
BGND power cable
-48V power cable
Do not install or demount the power cable while the power is on. To avoid personal injuries, turn off the power
before performing the operations.
The signal cable, power cable and fiber should be routed and bundled separately. Connect these cables in
sequence: PGND cable > BGND power cables > -48 V power cables.
When installing the PGND cable, connect the PGND cable to one grounding bolt on the cabinet and to the
grounding bar on the other side.
