• For AC power, include an AC circuit that meets the power specifications of the switch, see Power Requirements for
Switch Modules, on page 115. This circuit must include receptacles that match your local and national requirements
and match the needs of the power cable that is used with the power supply unit.
• For DC power, include a DC circuit that meets the power specifications of the switch see Power Requirements for
Switch Modules, on page 115). This circuit must include a circuit breaker so that you can safely connect the power
cables to the power supply.
Inspecting the New Switch
Before you install a new chassis, unpack and inspect it to be sure that you have all the items that you ordered.
Verify that the switch was not damaged during shipment.
When you handle the chassis or its components, you must follow ESD protocol to prevent ESD damage.
This protocol includes but is not limited to wearing an ESD wrist strap that you connect to the earth
ground.
Caution
Do not discard the shipping container when you unpack the switch. Flatten the shipping cartons and
store them with the pallet that was used for the system. If you move or ship the system in the future,
you will need these containers.
Tip
Step 1 Compare the shipment to the equipment list that is provided by your customer service representative and verify that you
have received your ordered items. The shipment includes boxes for the following:
• System chassis, which includes the following installed components:
• Supervisor modules (1 or 2) of the following types (must be the same type):
• Supervisor A (N9K-SUP-A)
• Supervisor A+ (N9K-SUP-A+)
• Supervisor B (N9K-SUP-B) (required for -R line cards and fabric modules)
• Supervisor B+ (N9K-SUP-B+) (required for -R, -R2 line cards and -R, -R2 fabric modules)
• System controllers (2) (N9K-SC-A)
• Line cards (1 to 8 line cards) as described in the Overview in Chapter 1.
• Fabric modules—See the Overview in Chapter 1 for quantity and type. The switch must have only one type of
fabric module that supports the installed line cards.
The fabric modules must be installed in specific slots as follows (installing fabric modules in other slots can cause a
module mismatch condition):
