3 1. Overview. Netrunr Edge Server (NES) is designed to provide connectivity, compute and storage functionality for your IoT network deployments. The NES architecture is optimized to support large scale data networking functions. A quad-core x86-64-bit processor is connected high speed interfaces like three gigabit ethernet ports, three mini-pci Express slots (mpcie), two external USB 3.0 ports, four internal USB 2.0 ports, SATA port, SD card and multiple GPIOs. 2.

4 The front panel of Netrunr Edge has three user-programmable green LEDs. The LEDs are connected to following pins of AMD FCH south bridge as listed in Table 1. LED PIN ID Default Function LED1 G57 Power/Heartbeat LED2 G58 WAN activity LED3 G59 SSD hard drive activity Table 1: LED connections Software to control is provided as Linux kernel module through Axiomware software repository on Github ( 3.2 Back Panel The back panel of the NES has ports listed in Table 2. Default functionality (as WAN or LAN) of ethernet ports can be modified using software. Functionality of ANT1 and ANT2 is dependent of installed options. PORT Default Function Connector/Type ANT1 Dual-band Wi-Fi Antenna RP-SMA RS232C Serial port (DTE) DB9 LAN1 LAN Gigabit ethernet RJ45 LAN2 LAN Gigabit ethernet RJ45 WAN WAN Gigabit ethernet RJ45 USB Dual USB 3.0 Host ports USB host 12V DC power input Barrel (center power) ANT2 2.4GHz Bluetooth Antenna RP-SMA Table 2: Back panel Figure 2: Back panel Power is supplied by a barrel connector (5.5mm OD, 2.5 mm id), with center pin at 12V. Nominal power consumption of Netrunr Edge server is TBD. 4

5 WAN port supports Wake-on-LAN (WOL) feature. LAN 1 and LAN2 ports do not support WOL features. WOL can be activated by the events listed in Table 3. Most common WOL systems use Type G events. Event type P U M B G Description Wake on PHY activity Wake on unicast messages Wake on multicast messages Wake on broadcast messages Wake on MagicPacket Table 3: Wake-on-LAN event types 3.3 Serial port (RS232C)/Boot-up The back panel serial port is live from BIOS startup to full operating system bootup. The default serial port parameters are N1, with no flow control. Pin-out of the port is listed in Table 4. A null-modem cable must be used to connect to another computer. Press F10 during bootup to enter boot devices selection, select Payload[setup] to select BIOS options. This serial port access is useful during development phase and porting of operating system. During regular production use, network ports (WAN/LAN1/LAN2/Wi-Fi) can be used for access and control of NES.

Internals. Open the metal enclosure of NES to access the mini-pciexpress slots, SD card slot, SATA and the dual simcard. It is recommended that NES is powered-down during this operation. The main CPU is on the bottom side of the PCB. The bottom section of the enclosure is thermally connected to the processor and functions as heat-sink. Four screws are used to secure the motherboard to the bottom section of the enclosure. A thermal compound is used at the interface between the heatsink and processor. Major connectors of NES motherboard are listed in Figure 3. Use Figure 4 to identify the pin 1 location of specific connectors that are listed below. 5

6 Figure 3: NES motherboard - internal component identification 4.1 Mini-PCI express slots Netrunr Edge Server provides ample expandability and customization using three mini-pciexpress connectors. Please refer to Table 5 for details of capabilities of each slot. NES has dual SIM card. In normal configuration, J2 SIM card is connected to J14 slot and J1 SIM card is connected to J15 slot. SIM card can be swapped by software using GPIO G33 (due to pull-up logic, 0 = swap, 1 = normal operation).

The two USB ports on J13 is used for Wi-Fi and Bluetooth radios. The two USB ports on J17 are unused. Both the ports follow the PC standard for internal USB ports. The 5V supply pins on J13 and J17 can supply up to 1A current, each. The pin-out of J13 and J17 is listed in Table 6. The two USB ports in each connector are identified as USB1 and USB2. 6

SD card interface is directly connected to main CPU. Use sdhci driver to access this feature. 4.4 SATA J6 SATA connector can be used for drives. J7 provides 5V for SATA drives. SATA drives can be used for data storage or as boot medium (main OS). 4.5 COM2 port NES provides an additional COM port on J4 header. This COM is low voltage (not RS23 signal levels). Do not apply high voltage to the pins. Pin Signal 1 3.3V 2 TXD 3 RXD 4 GND 5 5V Table 7: COM 2 port 4.6 I2C and LED The J5 connector is unpopulated. This connector can be used access the I2C bus.

To install driver support for temperature sensor, please install the lm-sensors package. Under Debian 9, use the following command: # Install software > sudo apt-get install lm-sensors # Execute software > sensors k10temp-pci-00c3 Adapter: PCI adapter temp1: C (high = C) (crit = C, hyst = C) fam15h_power-pci-00c4 Adapter: PCI adapter power1: 9.27 W (interval = 0.01 s, crit = 6.00 W) 4.10 Wi-Fi Netrunr Edge uses a Realtek RTL8811CU Wi-Fi radio. This is a dual-band ac (abgn+ac) Wave2, MU- MIMO chipset. Since this radio was recently released, the drivers may not be present in all Linux distributions. 8

Axiomware provides the source code and instructions for compiling the wireless drivers on our Github repository Bluetooth Netrunr Edge uses the BCM20704, a dual-mode Bluetooth 4.2 SoC from Cypress Semiconductor. All current Linux kernels (3.10+) have built-in driver support. An external 5dBi antenna is provided for optimal coverage Motherboard chipset support All devices on the NES motherboard are supported by current Linux distributions by default. Please contact Axiomware if a specific feature is missing. 9

10 4.13 AES-NI support NES processor supports AES-NI instructions to accelerate AES-128 and AES-256 operations. All current encryption and VPN frameworks on Linux will use AES-NI instructions by default. AES-NI will provide 10x to 50x boost for encrypted streams on the gigabit interfaces. 5. Known issues and fixes. 5.1 I2C address conflict between SP5100 watchdog timer and piix4 If watchdog timer is not required, the changes listed below are not required. A warning message is printed out during boot process; this can be safely ignored. To enable the use of SP5100 watchdog timer, blacklist piix4. The following commands can be used in Debian 9: # login as root user > su > cat > /etc/modprobe.d/blacklist<<eof blacklist i2c_piix4 EOF # update > update-initramfs -u # reboot > reboot 10
