What are the different ways that a 1130 AP can detect and receive power?
A. These are the different methods by which the 1130 AP can detect and receive power: • Cisco inline power (detected with a capacitance method), referred to as a “pre-standard method” because it was designed prior to the introduction of IEEE 802.3af. • 802.3af standard (detected with a resistive method). This can be either a 802.3af capable switch or an 802.3af mid-span device, which basically inserts power into the line much as does a power injector. • Power injector mode. The power is sent through a Cisco powered injector, which is a smart method with a handshake, or through a manual “hack,” such as a simple application of power on the unused pairs when the correct polarity is known. • Cisco powered devices that use “Cisco Power Negotiation mode.” This is a Cisco device that can support 802.3af yet can supply power through the Cisco inline power method. The switch is able to detect devices by both resistive or capacitive methods. In order for the “Cisco Power Negotiation mode” to wor
