How to connect Cisco power injector?
Follow these steps to install the power injector:
- Plug a Category-5 Ethernet cable into the port on the power injector labeled AP.
- Plug the other end of the Ethernet cable into the WAN uplink Ethernet port of the access point.
- Plug a Category-5 Ethernet cable into the port on the power injector labeled Switch.
What is Cisco Aironet power injector?
The Cisco Aironet Power Injector (AIR-PWRINJ5) increases wireless LAN deployment flexibility of Cisco Aironet Access Points by providing an alternative powering option to local power, inline power-capable multiport switches, and multiport power patch panels.
What is PoE injector used for?
A PoE injector connects your PoE-enabled network device to a non-PoE LAN switch port. More specifically, a PoE injector can be used to connect a wireless access point, IP phone, network camera or any IEEE 802.3af/at-powered device (PD) to a network switch.
What is pre Standard 802.3 af switches?
Select the Pre-standard 802.3af switches check box if the access point is being powered by a high-power 802.3af Cisco switch. This switch provides more than the traditional 6 Watts of power but do not support the intelligent power management (IPM) feature.
What is a power injector?
Power injectors are also known as PoE injectors or midspans. They are small and straightforward hardware devices that you connect to your network to allow you to power other devices throughout your network.
What does PoE plus mean?
The updated IEEE 802.3at-2009 PoE standard, also known as PoE+ or PoE plus, allows for up to 30 W of power to Type 2 devices. That’s sufficient power for devices such as VoIP phones, wireless access points, and security cameras.
How far can PoE?
100 meters
Standard PoE has Ethernet cable distance restrictions of 100 meters (328 feet) for data and power transmission, whether for IEEE 802.3af (PoE) or 802.3at (PoE+).
Can I plug a computer into a PoE port?
No, it is not safe to plug an ordinary PC into a passively-powered 24V PoE switch output. Unlike standard 48V “active” PoE – i.e. 802.3af/at/bt – which checks whether the connected device needs to be powered, the “passive” PoE provided by 24V switches is always on if the port is configured to send power.
What is the difference between 802.3 AF and 802.3 at?
The big difference between 802.3af (PoE) and 802.3at (PoE+) is the amount of power delivered over each standard. 802.3af (PoE) can deliver 15.4 watts over Cat5 cables. 802.3at (PoE+) can deliver up to 30 watts over Cat 5 cables with 25.5 watts available to devices.
What is a Power over Ethernet adapter?
Power over Ethernet (PoE) is the process of sending electrical power and data over copper wire. The combination of data transmission along with power supplying hardware onto the same RJ45 Ethernet connector allows for the transmission of power over the network cabling.
