Cisco Systems 7513 manual Power

Product Overview

In systems with a single power supply, and in systems with redundant power when both power supplies are shutting down, the output fail LED lights momentarily as the system ramps down, but goes out when the power supply has completely shut down.

The power supplies feature the following three safety interlock features:

•An on/off switch with a locking mechanism on each power supply prevents the power supply from being removed from the chassis when the power supply switch is in the ON () position. When the switch is ON, a metal tab extends into a slot in the chassis. When the switch is OFF (O), the tab is raised and clears the slot.

•A captive installation screw at the bottom of the power supply front panel provides electrical grounding and prevents the power supply from vibrating or sliding out of the bay and dislodging from the power connectors in the backplane. (See Figure 5.)
