Tip If you have ordered a server with power supply redundancy (at least two power supplies), you do not have to power off the server to replace a power supply because they are redundant and
The server can run in two power modes:
•Main power
•Standby power
You can invoke a graceful shutdown or an emergency shutdown (hard shutdown) by using either of the following methods:
•Use the CIMC management interface. See either the Cisco UCS
•Use the Power button on the server front panel. To use the Power button, follow these steps:
Step 1 Check the color of the Power Status LED (see the “Front Panel LEDs” section on page
•Green indicates that the server is in main power mode and must be shut down before it can be safely powered off. Go to Step 2.
•Amber indicates that the server is already in standby mode and can be safely powered off. Go to Step 3.
Step 2 Invoke either a graceful shutdown or a hard shutdown:
Caution To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown of the operating system.
•Graceful
•Emergency
Step 3 Disconnect the power cords from the power supplies in your server to completely power off the server.
