Cisco Nexus 9508 - Connecting a 3-Kw DC Power Supply to a DC Power Source

•
The power switch on the power supply must be turned off (power switch set to 0).
Step 1
Verify that the circuit breaker for the DC power source is turned off.
Step 2
Verify that the power switch on the power supply is turned off (0).
Step 3
Connect the ground terminal ring on the power cable to the ground terminal on the DC power source and secure it in
place with a nut tightened to the appropriate torque setting for the terminal post.
Step 4
Connect the negative terminal ring on the power cable to the negative (-) terminal on the DC power source and secure
it in place with a nut tightened to the appropriate torque setting for the terminal post.
Step 5
Connect the positive terminal ring on the power cable to the negative (+) terminal on the DC power source and secure
it in place with a nut tightened to the appropriate torque setting for the terminal post.
Step 6
Connect the Saf-D-Grid connector on the other end of the power cable to the Saf-D-Grid receptacle on the power supply.
Step 7
Turn on the circuit breaker for the DC power source circuit.
Step 8
Turn on the power supply by pressing its power switch to on (1).
Step 9
Verify that the Output Power LED turns on and becomes green.
What to Do Next
After you finish connecting all of the power supplies to power sources and each of the power supplies is
operating, you are ready to connect the switch to the network.
Connecting a 3-kW DC Power Supply to a DC Power Source
If you are not using power redundancy or are using n+1 power redundancy, you connect all of the power
supplies in the switch to the same power grid. If you are using n+n power redundancy, you connect half of
the power supplies to one power grid and the other half of power supplies to another power grid (grid A power
supplies are on the left side of the switch and grid B power supplies are on the right side of the switch).
Before You Begin
•
The power supplies must already be installed in the chassis.
•
The power supplies must be close enough to be connected to the DC power source using the
customer-provided power cables.
•
Four 6-AWG lugs provided with the switch.
•
Customer-provided equipment and tools must include all of the following:
◦
Four power cables (6 AWG cables recommended).
If you use colors to designate positive and negative cables, you need two cables colored
for positive polarity and two cables colored for negative polarity.
Note
◦
Wire stripping tool
◦
Crimping tool
