Power-on Self Test When the VCN Access Point is plugged-in, the VCN AP immediately starts

(POST)the power-on self test (POST) sequence as indicated by the power LED flashing in green. If the VCN AP is not powered, the power LED remains OFF. Check the power connections and the ac/dc adapter.

The power-on self test verifies that every component of the VCN AP is fully functional. The power-on self test lasts for 30 seconds at the most, during which time it is orange. If the power-on self test is successfully completed, the power LED turns green. If the power-on self test detected a VCN AP failure, the power LED remains orange. In this case, contact 3Com technical support; refer to Appendix F, Technical Support.

Use the front panel LEDs to determine each port’s status:
