#6. and #15. - 16. Backplane Main Power
Connectors
The power connectors, designated MP1
for BPN-NVMe-136PL and MP1, MP2,
PSU1, and PSU2 for BPN-NVMe-136PL-
J, provide power to the backplanes. MP1
of BPN-NVMe-136PL connects to MP1 or
MP2 of BPN-NVMe-136PL-J. See the table
on the right for pin definitions for the 12-pin
connectors.

#1. - 3. and #9. - 14. Amphenol Connectors
The Amphenol ports are used to connect
the Amphenol slim-line cables between
BPN-NVMe-136PL and BPN-NVMe-136PL-
J. They are designated MCN1, MCN2, and
MCN3 for BPN-NVMe-136PL and MCN1,
MCN2, MCN3, MCN4, MCN5, and MCN6
for BPN-NVMe-136PL-J. To connect two
BPN-NVMe-136PL SSD trays to one BPN-
NVMe-136PL-J JBOF/NVMF Controller,
MCN1, MCN2, and MCN3 of the first BPN-
NVMe-136PL should be linked to MCN1,
MCN2, and MCN3 of BPN-NVMe-136PL-J,
and MCN1, MCN2, and MCN3 of the sec-
ond BPN-NVMe-136PL should be linked to
MCN4, MCN5, and MCN6 of BPN-NVMe-
136PL-J.

#4. - 5. and #8. PCIe Slots
The PCIe slots are designated MJ1 and
MJ3 for BPN-NVMe-136PL, and JPCIE1
and JPCIE2 for BPN-NVMe-136PL-J. The
slots of the BPN-NVMe-136PL are where
the NVMe daughter cards are installed, with
BPN-NVMe3-136NB-L connecting to MJ1
and BPN-NVMe3-136NB-R connecting to
MJ3. JPCIE1 and JPCIE2 can each support
an NVMe over Fabrics card.
