Avaya 555-245-600 manual Switches from Extreme Networks, Power over Ethernet PoE

Avaya C360 converged stackable switches

●Simple network time protocol (SNTP) or TIME protocols are available to provide a consistent timestamp to all switches from an external source.

●Radius authentication enables centralized user management.

●You can use all appropriate tools of the Avaya Integrated Management suite for administration.

●System logging can occur by terminal, internal file, or Syslog server.

●Switch access can be restricted to specified protocols or services.

●You an restrict access to management interfaces by IP address.

●You can invoke a telnet client from the CLI.

Power over Ethernet (PoE)

●PoE is supported on the C363T-PWR and C364T-PWR switches.

●PoE is fully compliant with the 802.3af-2003 standard.

●PoE provides up to 15.4W per port (on10/100 ports) over Ethernet cables to power IP phones, wireless access points, and other end-points using 802.3af-2003 standards.

●PoE automatically detects device connections and removal.

●PoE automatic load detection does the following:

-Tests whether the device connected to the port requires remote powering.

-Controls the power injection to the wires.

●Power is distributed between the 24/48 PoE ports according to priorities that you configure. Power priority can be configured on each port. Distribution is calculated from actual power consumption.

Switches from Extreme Networks

Avaya recommends the following switches from Extreme Networks for use with Avaya VoIP:
