N-FXE-xxx-02 User Guide, 33509 Rev. D 5
1 Introduction
This document applies to the Lantronix N-FXE-xx-02 100Base-FX Fiber Adaptor NIC Cards.
Product Description
The N-FXE-xx-02 Series is a Fiber Fast Ethernet to PCI-Express (PCIe) bus adapter that fully complies with
all IEEE 802.3u and 100Base-FX standards. It provides up to 200Mbps full-duplex bandwidth capacity to
support high-end systems. In addition, with advanced functions like VLAN filtering packet processing, the
adapter provides added performance, flexible configuration and secure networking to users in a
standards-based environment.
The PCI-Express (PCIe) design gives you the maximum possible bandwidth and bus efficiency, along with
low power consumption. For users equipped with PCI-Express systems, N-FXE-xx-02 Series provides the
ability to easily build or connect to Fast Ethernet fiber networks.
Two LED indicators (LINK/ACT and FDX) on the bracket display NIC link activities and full-duplex status.
The N-FXE-xx-02 support Preboot Execution Environment (PXE). The Multi-Boot Agent (MBA) software
module lets your networked system boot with the images provided by remote systems across the
network.

Installation Procedure
CAUTION: Wear a grounding strap and observe electrostatic discharge precautions when installing the
N-FXE. Failure to observe this caution could result in failure or damage of the N-FXE.
WARNING: Turn power OFF before installing the N-FXE.
To install the N-FXE:
1. Turn OFF power to the PC or file server and unplug the power cord.
2. Remove the cover from the PC or file server and keep the retaining screws.
3. Select an empty PCI-e slot (see system documentation if unsure where PCI-e slots are located) and
remove the faceplate. Keep the faceplate.
4. Remove the network N-FXE from the shipping package and store the packaging material in a safe
place.
5. Apply even pressure on the corners of the N-FXE, pushing down until it seats firmly into the PCI-e
slot.
6. Replace the PC or file server cover and secure it with the screws removed in Step 2.
7. Power up the PC or file server.
Network Remote Boot Configuration
Select remote boot type
To enter the MBA configuration menu to select remote boot type (PXE), press SHIFT-F10 keys within 3
seconds after powering up the PC, otherwise the computer will load the OS.
Set network remote reboot
To set the network remote boot, enter PC BIOS first and then select the Boot tab, after that choose MBA
as the priority.
Cancel network remote boot
To cancel network remote boot, change the PC BIOS setting for MBA to Hard Drive or devices.
