2.4 Low Power Mode
In applications requiring low power consumption (such as solar power - not 7/24 mode) is strictly
recommended to use LPM mode prior to powering down the entire router.
LPM (Low Power Mode) is a router mode where the router is in sleep mode with minimal power con-
sumption; see Chapter 4.1 for the LPM consumption. The router can be woken up from this mode after a
predetermined period of time. Putting the router into LPM mode can be done using the
lpm
command, see
Commands and Scripts application note for more details.
2.5 USB Port
There is one USB 2.0 host port with a USB-A type socket. The router supports USB Mass Storages and
FTDI serial converters. For guidance on how to address an unsupported FTDI chip, refer to the Commands
and Scripts application note, specifically the chapter on How to Use Unsupported FTDI Chip.
The USB port is designed to disable on overload to prevent potential damage (occurs when a connected
device draws excessive current). The port is re-enabled after the router is rebooted.
Mounting USB Flash Drive to the System
To access a USB flash drive in the router’s system, it must be mounted. Follow these steps to mount the
drive:
• Use the dmesg command to view the list of recently connected devices.
• Identify the entry for the USB flash drive in the command’s output, for example:
sda: sda1
• To mount the drive to the mnt directory, use the mount command:
mount /dev/sda1 /mnt
For more information about the commands for creating, mounting, checking, and unmounting a file system
on a USB Flash Drive, consult the application note for the Ext4_tools router app.
