1. Remove the UTran PCI-ENC8G-24UM-2X2 enclosure from its packaging, and
place the enclosure next to computer, server, or workstation.
2. Hold one of the U.2 drive trays from the enclosure and push its button
downward for the release of the lever until the lever pops out.
3. Enclosure Installation

7
3. Place a U.2 drive tray on a flat and level surface, and then attach the 2.5” U.2
NVMe SSD into the tray.
4. Adopt four of the screws provided, and fasten the U.2 NVMe SSD on the tray.
Tighten each screw to fasten the U.2 NVMe SSD snugly to the drive tray. Do
not tighten the screws overly.
5. Insert the U.2 drive module into the PCI-ENC8G-24UM-2X2 enclosure until its
lever appears to shut, and then press the lever to close until it clicks to
ensure that the U.2 drive module is within the enclosure.
※Do not force the levers to close while you insert U.2 drive modules
into the enclosure. If a lever does not close smoothly, draw out and
insert the U.2 drive module again, and then press the lever to close.
Clicks!
※You must verify the heads of the four screws are
level with the U.2 drive tray while the 2.5” U.2
NVMe SSD 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.

6. Repeat steps 2 to 5 for further U.2 NVMe SSD drives.
7. Connect US_PM-2425 enclosure to the host card in server/computer through
the HD mini-SAS (SFF-8644) to HD mini-SAS (SFF-8644) data cables.
Connection types between PCI-ENC8G-24UM-2X2 and host server are shown atsection 4
of the user’s manual.
8. The PCI-ENC8G-24UM-2X2 enclosure is with redundant PSU, so connect one end of the
two power cords to the two power receptacles at rear of US_PM-2425 enclosure,
and then connect the other end of the two power cords to the power outlets.

Users can use the Command Line Interface (CLI) to manage the NVMe JBOF
functions.
US_PM-2425 NVMe JBOF utilizes the USB port as the serial port interface.
Please use USB Type-A male to USB Type-B male cable to connect between
US_PM-2425’s switch controller and the computer/workstation; the operation
system will detect a new USB-to-Serial COM Port. Please use this serial port to
configure the switch controller.
USB port location :
Establish the Connection for the USB Port
The CLI function can be managed by using an ANSI/VT-100 compatible terminal
emulation program. The program installation procedure must be done before
proceeding to the CLI function. Whichever terminal emulation program is used,
it must support the XMODEM file transfer protocol.
Start up VT100 Screen
By connecting a VT100 compatible terminal or a computer operating in an
equivalent terminal emulation mode, all CLI administration functions can
be executed by the VT100 terminal.
There are a wide variety of Terminal Emulation packages; most of them are
very similar. The following setup procedure is an example from VT100
Terminal in Windows 10 operating system using the Tera Term tool.
※Notice : Tera Term is a VT100 Terminal Emulation program which is an
open-source, free, software implemented , Terminal Emulator tool.
6. CLI Manager

The Tera Term needs to be downloaded; here is the reference site:
https://tera-term.en.lo4d.com/
Step 1. Install and launch Tera Term program.
Step 2. To ensure proper communication between PCI-ENC8G-24UM-2X2 NVMe JBOF switch
controller and the VT100 Terminal emulation, please configure the
VT100 Terminal emulation settings to the values as below:
For “ Port ”, select COM3 .
(COM3 is the example; actual COM number will depend on the COM
port that is used on the host computer)
For “ Baud rate ”, select 115200 .
For “ Data ”, select 8 bit . For “ Parity ”, select none .
For “ Stop ”, select 1 bit . For “ Flow control ”, select none .
Click OK when the selection is finished.

Step 3. Select the Terminal emulation type, please go to the Terminal section
as shown below:
For “ Terminal ID ”, select VT100 .
Click OK when the selection is finished.
