Administrator Guide

After you supply power to the system, the fans operate at medium speed. The green (online) fan module, RPM, and line card LEDs are lit
and remain lit as long as the system is receiving power and is operational.
When you turn on power supplies and supply power to the chassis, the system performs a series of power-on self-tests (POSTs). RPM and
line card LEDs blink as the diagnostic programs run. No user interaction is required. You can observe the process on your console terminal.
When the boot process completes, the line card LEDs remain online (green) and the console monitor displays the CLI prompt.
Checking LED Status
After you power on the switch, you can check the system, fan, power status, and port activity using LEDs on the front panel of RPMs, line
cards, power supplies, and fan modules.
NOTE: You can also check system status using CLI show commands and the Simple Network Management Protocol (SNMP).
For more information about these options, see the Dell Networking Command Line Reference and Conguration Guides for the
C9000 Series .
When the C9010 successfully powers up or reloads:
• RPM LEDs display system status and management port activity.
• Line card port LEDs display link status and port activity.
• PSU and fan LEDs display individual PSU and fan operational status.
For RPM LED location, see Installing an RPM. All other LEDs are shown in illustrations in this section.
