Configurazione POE per telefoni Cisco 7960G su switch HP 1910 (JE007A)
Come indicato in Power over Ethernet (PoE) Power Requirements FAQ i telefoni 7960G supportano un metodo Cisco pre-standard di individuazione dell’alimentazione e non lo standard POE IEEE 802.3af.
Q. What is the difference between the Cisco original PoE products and the IEEE 802.3af standard?
A. The differences include:
• the amount of power that is available to the connected device
• the method used for device discovery
• the way that power is removed from the wire when a powered device is removedQ. What IP phone models support the Cisco pre-standard method of powered device detection?
A. These Cisco IP phones can accept Cisco pre-standard PoE from a card integrated with a Cisco Catalyst switch or a Catalyst in-line power patch panel:
• 7985G
• 7960G
• 7940G
• 7910G
• 7910G + SW
• 7912G
• 7905G
• 7902G
• 7962G
• 7975G
• 802.3af
These phones can draw local power from a power cube (CP-PWR-CUBE-2=) in addition to a country or regionally specific power cord (CP-PWR-CORD-xx=).
Gli switch HPE V1910-24G-PoE (JE007A) possono gestire telefoni che supportano un metodo Cisco pre-standard di individuazione dell’alimentazione abilitando l’opzione Non-Standard PD Compatibility per la rilevazione dell’alimentazione.
A riguardo si veda quanto riportato nel documento HP 1910 Gigabit Ethernet Switch Series User Guide-R1513:
