Two port notation profiles can be selected for the QM97x0 NDR switch systems. In both cases, each 
cage in the system's front panel holds two ports from the same ASIC, and the cage numbers are 

global: 

ASIC/Cage/Port:

ASIC/Cage/Port/Split: 

Initial Power On

Each system’s input voltage is specified in the 

Specifications

 chapter.

The power cords should be standard 3-wire AC power cords including a safety ground and rated for 
15A or higher.

Plug in the first power cable.
Plug in the second power cable.
Wait for the system upload process.

Check the frontal System Status LEDs and confirm that all of the LEDs show status lights 
consistent with normal operation (initially flashing, and then moving to a steady color) as 

shown below. For more information, refer to 

LED Notifications

System Status LEDs 5 Minutes After Power On

The system platform will automatically power on when AC power is applied. There is no 
power system. Check all boards, power supplies, and fan tray modules for proper insertion 

before plugging in a power cable.

It may take up to five minutes to turn on the system. If the System Status LED shows 
amber after five minutes, unplug the system and call your NVIDIA representative for 
assistance.
