Installing Power Supplies
To install a power supply, follow these steps:
Before you begin
-
To implement n+n redundancy, each PSU must be connected to a separate power grid. Otherwise, only one power grid is required.
-
There must be an earth ground connection to the chassis to which you are installing the replacement module. Typically, the chassis is grounded by its metal-to-metal connection with a grounded rack. If you need to ground the chassis, see Grounding the Switch.
Procedure
Step 1 |
Holding the power supply unit with one hand underneath it and the other hand holding the handle, turn the power supply so that its release latch is on the right side, and align the back end of the power supply (the end with the electrical connections) to the open power supply slot. Carefully slide the power supply unit all the way into the slot until it clicks into place.
|

Step 2 |
Test the installation by trying to pull the power supply out of the slot without using the release latch. If the power supply does not move out of place, it is secured in the slot. If the power supply moves, carefully press it all the way into the slot until it clicks in place. |

Step 3 |
Attach the power cable to the electrical outlet in the front of the power supply. Make sure that the other end of the power cable is attached to the appropriate power source for the power supply. If the power source has a switch, set it to the ON position. |

Step 4 |
Verify that the power supply is operational by making sure that the power supply LED is green. For information on what the power supply LEDs indicate, see the Switch LEDs. |
