Testing SuperMicro CSE-PTJBOD-CB2 Jbod Power Board and Power Supply. This power board switches the power supply on when power is applied. It also provides fan power and LED headers. The power board was eventually moved into the left drive bay.


Unpacking and testing out how standoffs will work.


First stack of 4 Jetson Tegra TK1 boards put together. Syba mPCIe cards installed.


Powered up two stacks using custom power cables. Mocking up where the remaining two stacks of Jetson Tegra TK1 boards will be located.


Closeup of custom 8-pin Mollex PCIe to DC-barrel 12v power cables.


Ultra-thin Cat6 cables bundled and routed out of the chassis. Rear panel of the chassis is removed to allow for easier cable routing.


Back of racked chassis showing all 16 Cat6 cable managed and plugged into a Brocade ICX6610. System powered up.

Bare Rosewill chassis with only the power supply installed.

More parts unpacked. Small mPCIe cards are Syba SD-MPE24031 GbE NICs.The white pigtails are 10-pin to 8P8C (RJ45) adapters that came with the Syba cards. We ended up not using the pigtails, and the Syba cards while installed are not cabled.

All 4 stacks Jetson Tegra TK1 assembled.

5.5mm DC Barrel pigtails used to create custom DC Barrel to 8-pin PCIe-style Mollex 12v cables.

First time powering up all 16 boards via the custom power cables.

System racked in a JLSE rack.

Closeup through back panel of chassis. Shows some weather stripping that was used to remove the sharp edges where the Cat6 leaves the chassis.
