Specifications

The IBP-G4X16-2 is a passive backplane supporting PCIe Gen1, Gen2, Gen3 and Gen4 speeds and x1, x2, x4, x8 and x16 link-widths.
Both slots are symmetric and can be used for the Dolphin PCIe uplink card or Add-in Card. (The silk print specifies an Add-in and
Target cable adapter slot – but this can be ignored when using any Dolphin uplink card).

•
Support PCIe x1/ PCIe x4/ PCIe x8/ PCIex16 PCIe 1.0 / PCIe 2.0 / PCIe 3.0 / PCIe 4.0
•
55.52(W) mm x 164.53(L) mm
•
Compliant to ATX / MicroATX cabinets.

Pin headers and connectors

The card has the following pin headers:
J1: PCIe x16 PCI-E 4.0 SMT Type Slot
- For PCIe Add-in Card
J2: PCIe x16 PCI-E 4.0 SMT Type Slot
- For Target cable adapter
ATXPR: Power Connector
- ATX 24-Pin Power Connector
FAN: FAN Power Connector (12V Output)
- JST compatible wafer 2pin (pitch=2.0mm) connector
FAN2: FAN Power Connector (12V Output)
- JST compatible wafer 3pin (pitch=2.54mm) connector
RESET J1: RESET Button
PWR ON: Power On Control from Target Cable Adapter to switch On/Off the ATX Power Supply
- JST compatible wafer 2pin (pitch=2.5mm) connector
Note: To enable the auto-switch power On/Off control the Target Cable Adapter must have design to provide PWR ON
connector and you need to use a cable to join both connectors.
PWR SW: Power Switch Pin Header
- 2pin Header (pitch=2.54mm)
POWER LED: 3.3V Power LED Pin Header
- 3pin Header (pitch=2.54mm)
