GW3089 GBlade Server Blade
Product Information
All product information and datasheets can be found here: https://www.gateworks.com/products/arm-server-blades/gblade-arm-server-blade/
Getting Started
The GBlade is pre-installed with Ubuntu Linux. To power the unit use an 802.3at PoE switch or inserter. The bottom 1GbE RJ45 is the PoE port by default. Contact factory for 10GbE PoE options. Typical power consumption is around 10-13W without any additional cards plugged into the NVME socket.
Serial Console Access
Once the unit is powered, the GBlade serial console can be accessed through the type C USB port through a cable to a desktop/laptop PC. The serial console uses an industry standard FTDI FT2232HQ USB to Serial/JTAG converter IC and will show up as a /dev/ttyUSBx device in Linux and can be accessed through a terminal program with the baud rate of 115,200. For other operating systems, virtual COM port (VCP) drivers can be found here: Link.
Example:
sudo screen /dev/ttyUSB1 115200,cs8
Once connected via the USB cable, SSH can be enabled (it is disabled by default) with instructions here: Enable SSH
Any server software (LAMP stack, etc) can then be installed with the package manager.
apt-get update apt-get install {your package}
JTAG & Firmware/OS Update
The GW3089 incorporates onboard a USB to JTAG FTDI chip to allow JTAG programming of the unit without the requirement for a separate JTAG dongle (GW16099) which is typically used on other Gateworks SBCs.
The JTAG software is under development so for initial programming please see the following link on updating from a TFTP server.
Ethernet
There are two Ethernet ports, 1GbE (management) and 10GbE (high speed data).
- (eth1) 1GbE RGMII port is on the bottom (PoE by default) - Note this interface is not enabled in the default Linux installation.
- (eth0) 10GbE XFI port is on the top - This port is brought up with DHCP in the default Linux installation.
Powering Gblade with PoE
Isolated 802.3at 1GbE active PoE is supported on the bottom 1GbE Ethernet port. The Gateworks GW10144 802.3at PoE power supply/inserter can be used to power individual units and/or during development. See link here for info on GW10144: Tycon Inserter
For rackmount applications a 802.3at PoE switch is recommended.
To use the 10GbE port for PoE powering the device, please contact Gateworks Sales.
USB Port
The Type-C USB port is only for serial console access. This port will not work as a standard USB port.
NVME Drive
The GBlade needs to be opened up to install a 2280 M-Key NVME flash storage drive. The Gblade supports PCIe Gen 3.0 x4 lanes.
The NVME drive will show up as /dev/nvme0 and /dev/nvme0n1 respectively in Linux.
Here are the basic steps to open the case and access the NVME socket.
- Remove the four frontplate screws using a T8 Torx driver.
- Remove the frontplate and move to the side. Note the LED cable does not need to be removed.
- Slide out the side plate on the side the LED cable is mounted on.
- The M.2 NVME socket should now be visible and a drive can be inserted. Secure the drive to the PEM towards the front of the unit and reinstall the frontplate.
Some example NVME speed tests with a Samsung 980 drive:
root@jammy-malibu:~# dd if=/dev/nvme0n1 of=/dev/null bs=1M count=10k 10240+0 records in 10240+0 records out 10737418240 bytes (11 GB, 10 GiB) copied, 14.9507 s, 718 MB/s root@jammy-malibu:~# sudo hdparm -tT --direct /dev/nvme0n1 /dev/nvme0n1: Timing O_DIRECT cached reads: 3068 MB in 2.00 seconds = 1535.23 MB/sec Timing O_DIRECT disk reads: 4710 MB in 3.00 seconds = 1569.63 MB/sec
LED
A front panel LED is supported.
When power is applied, the LED will be a solid green. The LED will present a green heartbeat pattern is shown once the board is booted into Linux.
LED Programming
To disable the heartbeat LED:
root@jammy-malibu:~# echo none > /sys/class/leds/green\:heartbeat/trigger #disable default green heartbeat root@jammy-malibu:~# echo 255 > /sys/class/leds/red\:status/brightness #set LED to solid RED

Thermal & Cooling Fan
The GW3089 uses the industrial temperature quad core Marvell CN9130 processor rated at 2.2GHz. The Tjunction rating for the processor is -40C to +105C. The GW3089 enclosure contains a built in CUI fan (model CUI CFM-4020BF-095-342-22) to keep the unit cool and provide airflow to the processor. When the unit first boots, the fan will turn on to full speed and then once Linux starts it will be under thermal control based on the processors AP core temperature.
The fan runs at specific set points. The trip points are set at 50C, 60C and 80C (as shown in the device tree here). Note also the processor will throttle down if the fan isn't able to achieve proper cooling with the fan.
The PWM values for the four default set points are as follows:
Fan Off < 50C Fan On 40% PWM = 50C to 60C Fan On 67% PWM = 60C to 80C Fan On 100% PWM > 80C
These can be adjusted through the device tree if required.
Fan specifications:
- Operating Voltage: 5VDC
- Typical Power Consumption: 1.45W
- Typical RPM: 9500 RPM, Min 8550, Max 10450
- Typical CFM: 11.88
- Typical Noise: 34.2 dBA
- MTBF: Typ. 70K Hours @ +40C
- Operating Temp: -10C to +70C
- Dual Ball Bearing
- Auto Restart Protection
- Polarity Protection
- Soft Start
- Tachometer Signal
- PWM Control
- Safety Approvals: UL, cUL, TUV, CE
- RoHS
The GW8901 uses standard Linux cooling-maps, thermal-zones and the pwm-fan driver.
There are several temperature sensors on the board, identified as 'thermal_zones'. These are shown in Linux under /sys/class/thermal:
root@jammy-malibu:~# ls -la /sys/class/thermal/ total 0 drwxr-xr-x 2 root root 0 Jun 27 18:28 . drwxr-xr-x 62 root root 0 Jun 27 18:28 .. lrwxrwxrwx 1 root root 0 Jun 27 18:28 cooling_device0 -> ../../devices/virtual/thermal/cooling_device0 lrwxrwxrwx 1 root root 0 Jun 27 18:28 cooling_device1 -> ../../devices/virtual/thermal/cooling_device1 lrwxrwxrwx 1 root root 0 Jun 27 18:31 cooling_device2 -> ../../devices/virtual/thermal/cooling_device2 lrwxrwxrwx 1 root root 0 Jun 27 18:28 thermal_zone0 -> ../../devices/virtual/thermal/thermal_zone0 lrwxrwxrwx 1 root root 0 Jun 27 18:28 thermal_zone1 -> ../../devices/virtual/thermal/thermal_zone1 lrwxrwxrwx 1 root root 0 Jun 27 18:28 thermal_zone2 -> ../../devices/virtual/thermal/thermal_zone2 lrwxrwxrwx 1 root root 0 Jun 27 18:28 thermal_zone3 -> ../../devices/virtual/thermal/thermal_zone3 lrwxrwxrwx 1 root root 0 Jun 27 18:28 thermal_zone4 -> ../../devices/virtual/thermal/thermal_zone4 lrwxrwxrwx 1 root root 0 Jun 27 18:28 thermal_zone5 -> ../../devices/virtual/thermal/thermal_zone5
An example temperature for thermal_zone0 would be 60738, or 60738/1000=60.738 degrees Celsius:
root@jammy-malibu:~# cat /sys/class/thermal/thermal_zone0/temp 60738
The zones are labeled below. The AP stands for application processor, or the main CPU, with a sensor for each core of the quad core CPU. The CP0 stands for 'co-processor'.
root@jammy-malibu:~# cat /sys/class/thermal/thermal_zone*/type ap-thermal-ic ap-thermal-cpu0 ap-thermal-cpu1 ap-thermal-cpu2 ap-thermal-cpu3 cp0-thermal-ic
Fan tachometer / tach rpm:
root@jammy-malibu:/sys/class/hwmon/hwmon0# cat fan1_input 9510

Enclosure
The GW3089 anodized enclosure uses the following screws for securing the board, fan and frontplate.
- Frontplate = Torx T8 Head, M3 x 8mm
- Fan = Torx T10 Head, M3 x 25mm
- Board standoffs = Hex 1.5mm Head M2.5 x 5mm
The CPU and 10GbE Phy have passive heatsinks to allow better cooling on these devices. When installing M.2 cards in the GW3089 make sure to take cooling into consideration. Most NVME and AI accelerators recommend some type of heatsink.
The narrow width of the GW3089 enclosure will only allow an 8 to 9mm heatsink (depending on height of devices on the M.2 card). When installing heatsinks make sure to align the fins to maximize cooling with the air flowing from the front to rear of the enclosure.
