1.1 Features
Chapter 1
Overview
The ARIA™Cybersecurity Solutions Myricom®ARC Series 10G network adapter (Myri-10G Adapter)
improves server and application performance by offloading a variety of server-intensive functions, such as
encryption or micro-segmentation. This specialized Ethernet adapter connects to a PCIe slot on a host system
and supports one or more 10G network interfaces.
When configured as Tx-only, the adapter acts as a “data diode,” isolating the network. In this mode, traffic
flows in one direction only, from low secure areas to high secure areas. This unidirectional security gateway
ensures non-secure traffic can only travel in one direction.
This document describes the adapter and provides the instructions for installing the adapter, Tx-only
firmware, and verifying the 10G Ethernet driver for Linux-based systems.
1.1 Features
The Myri-10G Adapter component supports the following features:
lHalf height and ½ length PCIe board
lTwo Lanai Z8ES CPUs @ 365 MHz
l2 MB RAM
lPCIe Gen 2 x8 host interface, with backwards compatibility for PCIe Gen 1
lFour LEDs (two per port)
l10G network interface ports (single- or dual-port)
See the following figure for an illustration of a dual-port card.

is labeled S. See the following table for a description of the different colors/states.
Color State Indicates
Green Solidly Lit The adapter is powered on and has established a 10G link.
Off The adapter has not established a link or Linux has not booted
yet.

2.1 Verifying the PCIe Expansion Slot
Chapter 2
Installing the Myri-10G Adapter
This chapter describes the following tasks for installing the Myri-10G Adapter hardware.
ARIA products are designed to be compatible with industry standards and typically install quickly without
significant effort. If you encounter any issues during the installation process, please contact ARIA customer
support for assistance ([e-mail]).
This chapter focuses on the physical installation and configuring the hardware for transmit (Tx) only.
2.1 Verifying the PCIe Expansion Slot
Prior to installing the Myri-10G Adapter, you should verify the expansion slot is compatible with
the card. The Myri-10G Adapterrequires a PCIe server slot with a minimum of 4 lanes, but a slot
with 8 lanes is recommended. For the best performance, you should check the slot to ensure a
secure electrical connection.
2.2 Installing the Physical Myri-10G Adapter
Installing the physical Myri-10G Adapter requires installing the adapter into a host system. You
can then install the firmware once the board is properly functioning in the host system. Installing
the firmware requires a tarball file that you can download to the host system at any time.
2.2.1 Installing the Adapter
To install the adapter:
The Myri-10G Adapter contains materials and parts that are susceptible to damage
caused by Electrostatic Discharge (ESD). Use static-safe procedures when handling
the card.
1. Close all active applications and shut down the operating system.
2. Turn off the computer and disconnect the power cord.
3. Open the computer chassis to find an available PCIe slot.
NOTE: Place the adapter in an expansion slot that is connected to the CPU that
will run your application.
4. Seat the adapter firmly into the PCIe slot until the card clicks into place.
5. Secure the adapter to the chassis with a screw.
6. Close the computer chassis and connect the power cord.
7. Power on the computer.
You can now install the firmware required for configuring the adapter for Tx only.

2.2.2 Installing the Tx-Only Firmware
NOTE: The TX-only firmware is supported on Linux systems only.
Once you have installed the hardware, you can install the Tx-only firmware. The firmware is
contained in a tarball file (.tar.gz) and is available from ARIACybersecurity Solutions Support
([e-mail]).
NOTE: You must be logged in as an administrator or have super user privileges to install the
firmware.
The commands for installing the firmware differs for CentOS and Ubuntu. The procedures for each
OS are provided in the following sections.
Ubuntu (18.04)
To install the Tx-only firmware on Ubuntu:
1. Place the tar.gz file in a temporary directory on the machine.
2. Extract the files.
tar xvf myri-tools-<version>-linux-64bit.tar.tz
3. Verify the required .mcp2 file is local to the system. This file contains the firmware that will
be installed in the EEPROMflash of the adapter.
4. Execute the ze-upgrade script from the <tools>/bin/ directory.
sudo ./ze-upgrade ../myri-eeprom-<version>.mcp2
5. Change the directory to /lib/firmware on the machine.
6. Delete or move all .dat files the card is currently using.
7. Copy the new .dat files from tarball (.tar.gz) to the /lib/firmware directory.
8. Update the firmware.
sudo update-initramfs -u
9. Reboot the system and verify the adapter is using the Tx only firmware.
./myri_info
The output reflects Tx-only firmware when successfully completed.

To install the Tx-only firmware on CentOS:
1. Place the tar.gz file in a temporary directory on the machine.
2. Extract the files.
tar xvf myri-tools-<version>-linux-64bit.tar.tz
3. Verify the required .mcp2 file is local to the system. This file contains the firmware that will
be installed in the EEPROMflash of the adapter.
4. Execute the ze-upgrade script from the <tools>/bin/ directory.
sudo ./ze-upgrade ../myri-eeprom-<version>.mcp2
5. Change the directory to /lib/firmware on the machine.
6. Delete or move all .dat files the card is currently using.
7. Copy the new .dat files from tarball (.tar.gz) to the /lib/firmware directory.
8. Update the firmware.
sudo dracut -f
9. Reboot the system and verify the adapter is using the Tx only firmware.
./myri_info
The output reflects Tx-only firmware when successfully completed. See Figure 2-1 for
example output.
