EB12N3 Installation
This chapter discusses the steps required to configure and install the EB12N3 evaluation board. All
available DIP switches and jumper configurations are explained in details.
The primary installation steps are:
1. Configure jumper/switch options suitable to the evaluation or application requirements.
2. Connect PCI Express endpoint cards to the downstream port PCIe slots on evaluation board.
3. Insert Evaluation Board into the host system (motherboard with root complex chipset).
4. Apply power to the host system.
The EB12N3 board is shipped with all jumpers and switches configured to their default settings, and in
general, they do not require further modification or setup.
Hardware Description
The PES12N3 is a 12 lane, 3-port PCI Express switch. It is a peripheral chip that performs PCI Express
based switching with a feature set optimized for high performance x4 applications such as servers and
storage. It provides fan-out and switching functions between a PCI Express upstream port and two down-
stream ports or peer-to-peer switching between downstream ports.
The PES12N3 has two PCI Express x4 downstream ports accessible through two x4 connectors. Each
port is capable of negotiating a x1, x2, or x4 link width. All endpoint cards connected to the 89EBPES12N3
must support at least one of these link widths.
Basic requirements for the board to run are:
‹
Host system with a PCI Express root complex supporting x4 configuration though a PCI Express x4
slot.
‹
x1, x2, or x4 PCI Express Endpoint Cards.
Host System
The evaluation board cannot be operated as a standalone unit. A host system implementing a PCI
Express root complex supporting x4 configuration through a PCI Express x4 slot is required to take full
advantage of the PES12N3’s capabilities. One such system is the SuperMicro X6DH8-G2 motherboard
equipped with an Intel E7520 chipset which was introduced in 2004 to deploy dual-processor server chipset
technology. The board has three PCI Express slots. All slots have x8 connectors. However, only two have a
x8 link width (J15 and J16). The remaining slot has a x4 link width. Refer to Figure 2.1 to identify the proper
connectors.
