www.dell.com | support.dell.com Figure 39-2. Order of PoE Termination 0 1 Terminate PoE 2 For the configuration in the first example in Enabling PoE on a Port: • Power for ports 7/1 and 7/2 is terminated first because it is configured with inline power auto. • Power for port 7/2 is terminated before PoE for port 7/1 because port 7/1 has a lower port number. • Power for port 7/0 is terminated last because it is configured with inline power static. When a failed PSU is replaced and there is sufficient power for PoE, power is automatically re-supplied for previously configured PoE ports, and power is supplied first to ports with the highest priority. Figure 39-3. Order of PoE Re-Supply 0 1 Re-supply 2 Power Additional PoE Ports on the S-Series By default, 320 Watts is available for PoE on the S50V and S25V models of the S-Series. You have the option of enabling more power by connecting the external Dell Force10 DC 470W Redundant Power Supply to the Current Sharing terminal of the S50V and S25V. This power supply is in backup mode by default, but you can use the power budget stack-unit command to allow that external power supply to be used for powering PoE ports. 790W is the maximum that you can allocate to PoE, although the combined output of the internal AC power supply and the external DC power supply is 940W. That external power supply is the only power supply that you can use to add power for PoE with the S-Series. Message 28 appears if you attempt to use the power budget command when an external power supply is not connected. Message 2 External Power Supply Not Found % Error: External power supply not found or incompatible external power supply. 744 | Power over Ethernet
