Input power LED is extinguished

The Input Power LED illuminates to indicate that the switch logic circuitry is receiving proper voltages. If the
Input Power LED is extinguished:
1. Inspect the power cords and connectors. Is the cord unplugged? Is the cord or connector damaged?
• Yes—Make necessary corrections or repairs. If the condition remains, continue.
• No—Continue.
2. Inspect the AC power source. Is the power source delivering the proper voltage?
• Yes—Continue.
• No—Make necessary repairs. If the condition remains, contact your authorized maintenance
provider.
