DC-Input Power Supply LEDs (Cisco 7513, Cisco 7513-MX, and Cisco 7576)
In systems with a single power supply, and in systems with redundant power when both power supplies
are being shut down, the output fail LED lights momentarily as the system ramps down, but is off when
the power supply has completely shut down.
The AC-input and DC-input power supplies are self-monitoring. Each supply monitors its own
temperature and internal voltages. (For detailed descriptions of the show commands used to monitor
environmental conditions, see the
“Cisco 7513 and Cisco 7513-MX Environmental show Command
Examples” section on page 2-31
.)
