Dell Edge Gateway 3003 Installation and Operation Manual

Configuring low-power states: S3 and S4

# sudo systemctl suspend

# sudo systemctl hibernate

Configuring system wake-up from low-power states (S3/S4/S5)—WLAN

1. Enable Wake on WLAN in the BIOS program. For more information on accessing the BIOS program, see Accessing BIOS settings. Alternatively, use Dell Command | Configure.

   # sudo /opt/dell/dcc/cctk --wakeonlan=enablewakeonwlan

2. Connect the system to a wireless network.

   # sudo nmcli dev wifi connect $SSID password $PSK ifname wlan0

3. Enable Wake on WLAN.

   # sudo iw phy0 wowlan enable magic-packet

4. Recheck the support status.

   # sudo iw phy phy0 wowlan show

5. Make sure wlan0 is up and running with the assigned IP address.
6. Perform sleep.

   # sudo systemctl sleep

   Or, perform hibernation.

   # sudo systemctl hibernate

7. Use another system to wake from WLAN (Supported tools: wakeonlan and etherwake).

   # sudo wakeonlan MAC
   # sudo etherwake MAC

Configuring system wake-up from low-power states (S3/S4/S5)—Real-Time Clock (RTC)

1. Sync the time between the Edge Gateway and operating system:

   (root)# hwclock --hctosys

2. Obtain the RTC timer sysfs:

   (root)# ls -a /sys/class/rtc/rtc0

3. Clean-up the timer:

   (root)# echo 0 > /sys/class/rtc/rtc0/wakealarm

4. For example, set the wake-up event for 60 seconds:

   (root)# echo +60 > /sys/class/rtc/rtc0/wakealarm

5. For example, place the Edge Gateway in suspend mode:

   (root)# systemctl suspend

   If successful, the RTC will wake up the Edge Gateway in 60 seconds.

Configuring system wake-up from low-power states (S3/S4/S5)—LAN

1. Enable Wake on LAN in the BIOS program. For more information on accessing the BIOS program, see Accessing BIOS settings. Alternatively, use Dell Command | Configure.

   # sudo /opt/dell/dcc/cctk --wakeonlan=enable

2. Enable Wake on LAN in nmcli (enabled by default).

   # nmcli c show “Wired connection 1” | grep wake
   802-3-ethernet.wake-on-lan: magic
   # nmcli c show “Wired connection 2” | grep wake
   802-3-ethernet.wake-on-lan: magic

3. Make sure the ethernet connection is up and running with the assigned IP address.
4. Perform sleep.

   # sudo systemctl sleep

   Or, perform hibernation.

   # sudo systemctl hibernate

5. Use another system to wake from LAN (Supported tools: wakeonlan and etherwake).

   # sudo wakeonlan MAC
   # sudo etherwake MAC
