4 Hardware Set-up / Installation
The following steps will guide you through the installation of your One Stop Systems expansion system.
4.1 Remove Top Cover
Remove the two (2) mounting screws on top of the chassis. Slide the enclosure cover towards the back of the unit to disengage it from the
guides and then lift the cover off.
4.2 Install Target Card
By default, the Target card is installed in the unit. The Target card is plugged in or installed in the Target slot. If the Target card is missing or not
installed, follow these steps.
Configure the card first; set the card switches to Target mode.
Plug in the Target card in the designated target slot (upstream slot) of the expansion system.
4.2.1 Target Card Configuration
SW1 #1 = ON; #2= ON
SW2 = All OFF

One Stop Systems
EB4400 (8SLOT BP) 18
Once the dipswitches are set correctly, plug in the target card, make sure it is fully seated in the PCie slot.
4.3 Install Host Card
Before installation, you must check the switches on the Host card.
By default, all the switches on the Host card are set to OFF position (“Auto-Negotiation” mode).
You can leave the switches to default or you can set the switches (SW1 and SW2) on the card for the desired Host operating mode.
See “Host Card Configuration” section for more details.
4.3.1 Host Card Configuration
The following are switch settings for the Host card.
x16 Dip switch Settings:
SW1 #2 = ON; #5 =ON.
SW2 #1 = ON; #2 = ON
x8 Dip switch Settings:
SW1 #2 = ON; #5 = ON
SW2 #1 = OFF; #2 = ON or #2 = OFF and #1 = ON

One Stop Systems
EB4400 (8SLOT BP) 19
x4 Dip switch Settings:
SW1 #2 = ON; #5 = ON
SW2 = All OFF
Once the Host-card is configured, install the card into a x16 Gen4 PCIe slot on a computer motherboard.
Check the PCIe slot for any foreign debris as this can damage the card during installation.
Align the host card PCIe connector on top of the PCIe slot and carefully push the card down until it is firmly seated.
Secure the card with the screw.
Below photo is an example of a x16 PCIe slot connectors. The photo on the right is a PCI-E 3.0 x16 slot. The specification of the PCIe slot is
printed on the board next to connector for easy identification. Use a x16 PCIe slot for the host card to achieve stable performance.
