A network engineer is installing new PoE wireless APs. The first five APs deploy successfully, but the sixth one fails to start. Which of the following should the engineer investigate first?
When deploying multiple Power over Ethernet (PoE) devices, the switch’s power budget can be exhausted. If the available wattage on the switch cannot supply the additional AP, it will fail to power on. This is the most likely cause when previous APs worked fine but a new one does not.
A. Signal strength affects wireless connectivity, not whether the AP powers up.
B. Duplex mismatch causes poor throughput, not power failure.
D. CRC errors point to cabling issues but do not prevent booting if no power is available.
