Peripheralsīƒ

The LAA provides many peripherals to automate the attached DUT. The peripherals can be controlled from the command line using laam.

Ethernet portsīƒ

Ethernet ports

Public ethernetīƒ

The public ethernet port is used to connect the LAA to the lab network. This network should let the LAA connect to the fleet management cloud service.

Private ethernetīƒ

This ethernet port is used to connect the DUT to the LAA in a private network managed by the LAA. In this network the IPs are:

  • LAA: 198.18.0.1

  • DUT: 198.18.0.2

DUT services

The LAA provides multiple network services on this interface: dhcp, dns, ntp, tftp, nfs, â€Ļ

OLEDīƒ

The OLED screen displays information about the status of the LAA:

  • IPv4

  • version (or target version if an upgrade is in progress)

  • serial numbers

  • organization

If the LAA is unable to get an IPv4 or to connect to the fleet management service, the right information will be displayed. More information on the connectivity guide.

Thermal probesīƒ

The LAA comes with 2 embedded thermal sensors and a thermal probe connector.

Thermal probe

The values can be fetched with:

laam laacli temp amb  # ambiant
laam laacli temp dut  # thermal probe
laam laacli temp sys  # CPU

USB portsīƒ

USB connectors

DUT USBīƒ

  • Port 1: type-C with power delivery

  • Port 2, 3 and 4: type-A

Each port can be controlled from the command line with

laam laacli usb 1 on
laam laacli usb 1 off

LAA USBīƒ

There is 2 USB port on the front of the LAA:

  • USB OTG port

  • Serial over USB: LAA serial console

The USB OTG port can be used to provide a mass storage device using USB gadget mode (USB mass storage emulation):

laam laacli usbg-ms on filename.img
laam laacli usbg-ms off
