Data Sheet

Feature

Description

Cisco Discovery Protocol (CDP)

The switch advertises itself using the Cisco Discovery Protocol. It also learns the connected device

and its characteristics via CDP.

Power over Ethernet (PoE)

802.3af PoE and 802.3at PoE+

delivered over any of the RJ-45

ports within the listed power

budgets

Switches support 802.3at PoE+, 802.3af, and Cisco pre-standard (legacy) PoE. Maximum power of

30.0W to any 10/100 or Gigabit Ethernet port for PoE+ supported devices and 15.4W for PoE

supported devices, until the PoE budget for the switch is reached. The total power available for PoE

per switch is as follows:
