Explanation

Procedure for Power Failures on PoE-Powered HP V1810G8 Switches HP V1810G-8 switches can be powered by PoE instead of by a traditional power source. When they are, you must use a different procedure to troubleshoot. First, use a known good RJ-45 cable to connect the V1810G- 8 port 1 (the port that receives PoE) to the PoE power source (which might be an injector or a PoE switch). If this does not solve the problem, check the PoE source and verify that it has enough power to supply to the V1810G switch (15W). Finally, if the PoE source is a switch, have the switch administrator check the PoE priority of the port that connects to the V1810G-8. The priority must be high enough to ensure that the switch will deliver power to the V1810G-8. Once you are certain that the PoE source is delivering the proper amount of power, check the V1810G- 8 Power LED. If it is still not illuminated, the switch has failed. Replace it.
