Backplane and LED Board Wiring
1. LED board signal cable: Get the HDD activity signals and internal protocol for the spin up of each
backplane. This cable connects the backplanes (start from #1) and LED board.
2. Discrete HDD failure signal cable: This cable is optional for the HBA or RAID card with HDD failure signal
support. It is connected by direct cable connection, and each backplane needs one 4P-4P discrete cable.
3. Fan connection: Connect the fan cable from Fan#1 to Fan#5 sequentially, and configure the fan quantity
and monitoring setting DIP on the LED board accordingly.
4. Power connection: Connect the power connector from PSU. Since each backplane needs two 4-pin power
connectors, it is strongly recommend do NOT using 4-pin connectors from same power wire for any single
backplane.
5. HDD cable: Refer to ā€œMini-SAS Cablesā€ session for detail below. Check the responded HBA or RAID card
before installing.
