Replace DXi T10 Power Supplies
Overview
The DXi T10 chassis features redundant power supplies, so that the system will continue to operate if one module fails. Failed power supplies should be replaced as soon as convenient. The power supply modules are hot-swappable, meaning they can be changed without powering down the system.
These power supplies are auto-switching capable. This feature enables them to automatically sense the input voltage and operate at a 100-120v or 180-240v as needed by the system.

| Solid Amber | When illuminated, indicates the power supply is plugged in and turned off, or the system is off but in an abnormal state. |
| Blinking Amber | When blinking, this system power supply temperature has reached 63ºC. The system will automatically power-down when the power supply temperature reaches 70ºC and restart when the power supply temperature goes below 60ºC. |
Replacement Procedure
Required Tools: There are no tools required for this component replacement.
Note: This component is hot-swappable. You do not need to stop all I/O from clients or remove power to replace this component.
Take ESD precautions when performing this replacement
The chassis is designed to dissipate all electrostatic discharge (ESD) to the chassis base. Ensure that there is sufficient electrical and mechanical connection from the chassis base to the rack rails, and that the rack itself is tied to earth ground. The unit must be grounded in accordance with all local/regional and national electrical codes.
Some components within the node contain static-sensitive parts. Precautions must be taken to ensure that the system is not exposed to ESD while handling components or servicing the unit. To avoid damaging these parts while performing maintenance procedures, always observe the following precautions:
-
Keep static-sensitive parts in their original shipping containers until ready for installation.
-
Do not place static-sensitive parts on a metal surface. Place them inside their protective shipping bag or on an anti-static mat.
-
Wear anti-static wrist bands when unpacking and handling the units, and avoid touching connectors and other components.
-
Dry climates and cold-weather heating environments have lower relative humidity and are more likely to produce static electricity.
-
Unplug the power cord from the failed module.
-
Push the release tab (on the back of the power supply) as illustrated, then pull the power supply out using the handle provided:
-
Push the new power supply into the power bay until you hear a click:
-
Connect the power cord to the power supply.
