The 7705 SAR-H supports Power over Ethernet (PoE) on all four 10/100/1000 copper Ethernet ports. To use PoE, the PoE power source must be configured at the system level as either internal or external. When the system is configured for the internal PoE power source option, PoE capability can be enabled on ports 5 and 6 only. In addition, port 5 can be enabled for PoE+ but in that case, port 6 cannot support any PoE capability. When the system is configured for the external PoE power source option, a mix of PoE and PoE+ is available on ports 5, 6, 7, and 8. See the 7705 SAR-H Chassis Installation Guide, ‟Ethernet Ports”, for information about supported combinations of PoE and PoE+.
To enable PoE or PoE+ on a PoE-capable port on the 7705 SAR-H, use the config>port>ethernet>poe command; see the 7705 SAR Interface Configuration Guide, ‟Configuration Command Reference”, for more information.
The PoE-capable ports on the 7705 SAR-H act as a Power Source Equipment (PSE) device. They support IEEE 802.3at and IEEE 802.3af.
The 7705 SAR-Wx (variants 3HE07616AA and 3HE07617AA) supports PoE+ on the RJ-45 Ethernet port with PoE+. The PoE+ ports are used to deliver power to a ‟Powered Device”, such as a non-line-of-sight (NLOS) or line-of-sight (LOS) microwave radio, at levels compatible with the IEEE 802.3at standard.
To enable PoE+ on a PoE+-capable port on the 7705 SAR-Wx, use the config>port>ethernet>poe plus command; see the 7705 SAR Interface Configuration Guide, ‟Configuration Command Reference”, for more information.
