4. Configuring Inline Power on the Cisco 2811 Integrated
Service Router
The Cisco 2811 Integrated Service Router with a NME-16ES-1G-P Blade and power
supply model number 341-0067-02 Rev A0 and type HP-U2850X5 supports 160 Watts of
inline power, which is enough to support Class 2 and some Class 3 PDs on all 16 ports.
The testing associated with these Application Notes did not cover loading of all ports on
the PSE.
The following describes how the Cisco 2811 router interacts with the power devices.
1. PoE capable ports are by default set to auto mode, meaning the Powered
Device Discovery is enabled. If the power from the Ethernet port is
