Caution - Your site must have a local power disconnect (for example, circuit breakers) between the power source and the power cords. Ensure that these circuit breakers are set to off before connecting the power cords.
Caution - Ensure that you install the server near your power grid's electrical outlets, and ensure that these outlets are easily accessible in case you must detach the power cords in an emergency.
Caution - This safest and preferred way to supply power to the server is to install the power cords while the power source circuit breakers are set to off. If you do not have access to the circuit breakers and the facility power cannot be switched off, only connect the power cords to the AC input filters at this time. When you power on the server for the first time, connect the IEC 60309 power cord plugs to the live facility power grid sockets.
The server receives power from six power cords. The server is designed to receive power from two separate power grids, with three power cords receiving power from one power grid and the remaining three power cords receiving power from a second power grid. You must connect all six power cords.
Note - To aid installing and servicing the power cords, label both ends of the power cords with the number of the AC input filter (AC0, AC1, AC3, and so on) or with a number specific to your facility.
Review the Power Cord Specifications to ensure that you received the correct power cords for your facility.
Review the Power Cord-to-Power Supply Relationship to understand which power cord supplies power to which power supply.
Review the Facility Power Requirements.
Review the Circuit Breaker Capacity Requirements to ensure that the circuit breakers accommodate your facility power infrastructure.
You will be connecting three power cords from one power grid to the left three AC input filters (AC0, AC1, and AC2) and three power cords from the second power grid to the right three AC input filters (AC3, AC4, and AC5).
If you are routing the power cords up, go to Step 6.
If you are routing the power cords down, continue to Step 5.
For more information about routing power cords and data cables, see Rear Cable Routing Options.
Route the power cord plug to the left-most AC input filter labeled AC0. Continue to Step 7.
Note - Do not overtighten the tie-wraps, and provide some slack in case you need to detach the power cord or replace the AC input filter. However, do not allow the power cord to lay on the cable management hooks below the AC input filters. These hooks cannot support the weight of the power cords.
If you are routing the power cord upward, thread the power cord out through the top of the server.
If you are routing downward, lead the power cord to the right cable channel. Continue to lead the power cord down the right cable channel and then through the floor cutout underneath the server.
Consult with your facilities manager or a qualified electrician for the specific instructions on how to connect the power cords at your data center.
By labeling these components, you will be able to replace the power cords to the appropriate outlets after servicing the server. When powering on the server for the first time, you will switch on each circuit breaker in the order of the AC input filters.
Note - If you have numbered these components using a numbering sequence unique to your facility, ensure that you can still determine the AC input filter number associated with each component.
Connect the cables from the left to the right. Ensure that each power cord is connected to the correct facility AC power grid.
Note - You must connect all six power cords.
