The switch is not
plugged into an
active AC power
source, or the
switch’s power
supply may have
failed.
1. Verify that the power cord is plugged into an active power source and to the switch.
Make sure these connections are snug.
2. Try power cycling the switch by unplugging and plugging the power cord back in.
3. If the Power LED is still not on, verify that the AC power source works by plugging
another device into the outlet. Or try plugging the switch into a different outlet or try a
different power cord.
If the power source and power cord are OK and this condition persists, the switch power
supply may have failed. Contact SMC Technical Support for assistance.
