Power over Ethernet for the Ethernet
Routing Switch 2526T-PWR and
2550T-PWR
The Ethernet Routing Switch 2550T-PWR and 2526T-PWR provide IEEE
802.3af-compliant power over half of the front-panel RJ-45 ports, located on
the left-hand side of the front panel. The switch provides power discovery,
power management, and statistics on power use on each port and each
switch basis. You can use the Ethernet Routing Switch 2500 Series to
provide power to network appliances, such as IP telephones, wireless
access points, and video devices.
The Ethernet Routing Switch 2526T-PWR and 2550T-PWR provide Power
over Ethernet for 12 and 24 ports with respectively. The switches only
support PoE on the lower-numbered ports (identified by a red border). The
switches provide a maximum of 168 Watts of power to PoE ports. Adequate
power is available to supply, on average, 7 Watts for each port on the
2550T-PWR, and 14 Watts for each port on the 2526T-PWR. A maximum of
15.4 Watts is available on any port for any given device.
The Ethernet Routing Switch 2550T-PWR and 2526T-PWR supply data
terminal equipment (DTE) power only on signal pins.
By default, power is allocated based on real time measurements. If the total
Ethernet power budget for the switch is exceeded, the switch sheds load
by shutting down power to ports.
You configure the Power over Ethernet (PoE) parameters on the PoE ports
using the Command Line Interface (CLI), the web-based management
system, or Device Manager (JDM).
