Replacing a power supply
The design of the 6900/8900 platform is such that you can remove a power
supply from the chassis without powering down the system, provided that
there is at least one power supply operating during the replacement process.
To replace a power supply
1. Disconnect the AC power cord or DC wiring block from the power
supply.
2. Loosen the power supply screw by turning it counterclockwise,
using an appropriate screwdriver if necessary.
Note:
The screws that hold the power supplies to the chassis are
captive and cannot be removed.
3. Grasp the ejector handle and rotate it downward to eject the power
supply from the system.
4. Remove the power supply from the system by pulling straight
toward you.
5. Ensure that the latch on the new power supply is in the down
position and slide the power supply into the power supply slot until
the latch engages.
6. Rotate the latch upwards to fully seat the power supply.
