1.1 Overview
PCI-ENC8G-024U 2U24bay PCIe NVMe JBOF enclosure is designed to provide an external NVMe
storage solution. The enclosure is equipped with two PCIe switch controllers, supporting a total
of twenty-four (24) high-speed SFF-8639 NVMe SSDs. Each controller integrates the Avago
Technologies ExpressFabric Capella 2 PCIe switch PEX9781 with eight external mini-SAS HD
connectors, designed to provide PCIe expansion. The total maximum bandwidth is PCIe Gen3
x64 512GT/s and allows up to 8 head-nodes access the NVMe JBOF enclosure.
1.2 Package Checklist
Before the installation of the enclosure, verify the items below are included in the package.
A. Enclosure × 1 B. HDD tray (installed in the PCI-ENC8G-024U) ×
24
C. Hard disk drive mounting screw × 96 D: AC Power cord x2
E. Package of slide rail× 1

2.2 Enclosure Setup
1. Remove the PCI-ENC8G-024U enclosure from its packaging, and place the enclosure next to
PC, server, or workstation.
2. Hold one of the drive trays from the enclosure and push its button downward for the release of
the lever until the lever pops out.
3. Place a drive tray on a flat and level surface, and then attach the drive into the tray.
WARNING:
You must verify the heads of the four screws are level with the drive tray while the drive is attached
to the tray; otherwise, a screw may take hold of the tray from the bottom side and prevent you to
pull the tray out of the enclosure.
4. Use four of the screws provided, and fasten the drive on the tray. Tighten each screw to fasten
the HDD snugly to the drive tray. Do not overly tighten the screws.
WARNING:
Do not force the levers to close while you insert drive modules into the PCI-ENC8G-024U enclosure.
If a lever does not close smoothly, draw out and insert the drive module again, and then press the
lever to close.
4
SERIAL CABLES NVMe JBOF User’s Manual
5. Insert the drive module into the PCI-ENC8G-024U enclosure correctly until its lever appears to
shut, and then press the lever to close until it clicks to ensure that the drive module is within
the enclosure.
6. Repeat steps 2 to 5 for further drives.
7. Connect PCI-ENC8G-024U enclosure to the host interface: An external PCIe host adapter card
through an SFF-8644 mini-SAS HD data cable. The connection between the PCI-ENC8G-024U
enclosure and the external PCIe host adapter ports is shown as follows:
8. Connecting PCI-ENC8G-024U enclosure’s USB Port (optional)
‧
PCI-ENC8G-024U enclosure’s system functions can be managed via a COM port running a
VT-100 terminal emulation program, or a VT-100 compatible terminal.
9. The PCI-ENC8G-024U enclosure provides a redundant power supply unit. Connect one end of
the two power cords to the two receptacles on rear of PCI-ENC8G-024U enclosure, and then
connect the other end of the two power cords to the power outlets.
11. After the two power cords are connected, you can power on the PCI-ENC8G-024U enclosure
and the computer.

Location of USB
Port
NVMe JBOF enclosure uses the USB port as the serial port interface. Please us e the USB type A
male to Type B male cable to connect switch controller to PC and operation system will detect a
new “
USB-to-Serial COM Port”. Please use this serial port
