Power supply module overview
Power supplies can be removed and replaced without special tools. If replacing one power supply, the device can continue operating
during replacement if procedures are followed in this guide.
NOTE
Depending on the module conguration of the chassis and the number of power supplies installed, the device may be able to
continue operating during the replacement. Refer to the ExtremeRouting SLX 9850 Technical Specications on page 131 to
determine your power requirements. If insucient power is present, the chassis will start powering down modules until the
power demand can be met.
For a list of supported power supplies, refer to Supported hardware and software on page 11. For a description of the power supply
module LEDs, refer to Interpreting power supply module LEDs on page 80.
The following gure shows the components of the AC power supply.
