Switch LEDs

The following table describes the chassis LEDs for IBM SAN96C-7 switches:

Indicator Location Function Color Status State
Power LED Front panel of chassis Chassis power/Health Off Off

Either of the following conditions exists:

  • The system is not receiving sufficient power from the PSUs.

  • The operating system is not running.
Green Solid On Both PSUs are installed and operating
Red Solid On

Either of the following conditions exists:

  • A PSU has failed.

  • A PSU has been removed.
Status LED Front panel of chassis System Status Green Solid On All diagnostics have passed, Cisco NX-OS is running and the system is operational.
Orange Solid On

Any of the following conditions exist:

  • The system is running bootup diagnostics.

  • The system is booting.

  • A minor temperature threshold is currently exceeded.
Red Blinking

Mismatched airflow direction was observed in one of the following modules:

  • Fan modules—The switch will shut down in 20 seconds.

  • PSUs—The switch will power down after 10 minutes.
Solid On

One of the following conditions exists:

  • A diagnostic test failed or another fault occurred during bootup.

  • A major temperature threshold is currently exceeded.
Fan Status On the front panel Fan health Green Solid On Fan is operating normally
Red Solid On Fan has failed or Fan has been removed.
Faceplate of each fan module Fan tray health Green Solid on Fan module is operating normally.
Red Solid on The fan in the fan module has failed.
PSU Status Faceplate of each PSU PSU input/output Green Off No input to the PSU.
Solid on PSU output is OK.
Blinking PSU output is not OK, but input is OK.
PSU Operation Amber Solid on

One of the following conditions exists in the PSU:

  • Over voltage

  • Over current

  • Over temperature Fan failure.
Blinking PSU has a fault but is still operational.
Off PSU is operating normally.

The following table describes the Ethernet port LEDs for IBM SAN96C-7 switches.

LED Position Status State
Left Off There is no link.
Solid Green Indicates a physical link.
Right Off There is no activity.
Blinking Green Indicates activity.

The following table describes the Fibre Channel port LEDs for IBM SAN96C-7 switches.

Status State
Solid Green The link is up.
Regular Blinking Green The port beacon is active.
Intermittent Blinking Green The link is up (indicates that there is traffic on the port).
Solid Orange SFP is absent or the port is disabled by the software.
Blinking Orange A fault condition exists.
Off No link.
