➊The power supplies installed in the switch are not plugged into active AC power sources, or the power supply may have failed.
1.Verify the power cord is plugged into an active power source and to the switch. Ensure 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 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. Call your ProCurve authorized dealer, or use the electronic support services from ProCurve to get assistance. See the Customer Support/Warranty card for more information.
