FTOS Configuration Guide for the C-Series - Force10 Networks

Recovering from a Failed Power Supply
If ports are PoE-enabled, and a PSU fails, power might be terminated on some ports to compensate for the
power loss. This does not affect PoE individual port configurations.
For C-Series, use the show power supply command to display PSU status (Figure 453).
For S-Series, see the Power over Ethernet (PoE) chapter in the FTOS Command Reference for the S-Series
for an example of the output of the show power inline output and its field descriptions.

If power must be terminated for some ports, the order in which ports are affected is based on priority. Ports
with the lowest priority are terminated first (see Managing Power Priorities on page 646).

Terminate PoE
• 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.
