Power Supply Cooling; Load Sharing - Cisco SCE 8000 Installation And Configuration Manual

Chapter 2 Introduction to the Cisco SCE 8000 10 GBE Platform

Power Supply Cooling

Power supplies have built-in fans and are completely self-cooling. Air enters from the right of the fan
and exits through the left.

Load Sharing

With two power supplies, each power supply concurrently provides approximately half of the required
power to the system. If one power supply fails, the second power supply immediately assumes full power
to maintain uninterrupted system operation. The second power supply enables load sharing and fault
tolerance automatically; no software configuration is required.
