Before you begin
• Verify that the switch is fully installed and secured to a rack.
• Verify that the switch is adequately grounded to the facility earth ground or to a grounded rack.
• Verify that all of the fan and power supply modules are installed in the chassis. If the chassis has less
than 4 power supplies, there must be a blank module (NXA-PS-BLANK) in the open power supply slot
to maintain the designed airflow.
Step 1 If the switch has AC power supplies, connect those power supplies to an AC power source as follows:
a) Verify that the AC power source is turned off at the circuit breaker.
b) Plug the power cable into the power receptacle on the power supply.
c) Attach the other end of the power cable to the AC power source.
d) Turn on the power at the circuit breaker.
e) Verify that the power supply is functioning by making sure that the OK LED turns green and the FAULT LED is
off.
Step 2 Listen for the fans; they should begin operating when the power cable is plugged in.
Step 3 After the switch boots, verify that the following LEDs are on:
• Power supply LED—lit and green
If not green, try removing the module part way from its slot and reinstalling it.
• Fan LED—lit and green
If not green, try removing the module part way from its slot and reinstalling it.
• System Status LED—lit and green (if this LED is orange or red, then one or more environmental monitors is reporting
a problem.)
• Link LEDs for the Ethernet connector—Off
