10 Diagnostics and troubleshooting

This chapter describes MPX200 chassis diagnostics and provides information to help you
troubleshoot problems. Diagnostic information is also available through diagnostics, HP P6000
Command View, and the CLI event logs and error messages.

MPX200 chassis diagnostics

Chassis diagnostics are indicated by the chassis LEDs (see
NOTE: The USB port is unmarked and is not supported.

Input Power LED is extinguished

The Input Power LED is illuminated when the MPX200 logic circuitry is receiving the proper voltage.
If the Input Power LED is not illuminated:
1. Inspect the power cord and connectors on the back of the chassis
the cord unplugged? Is the cord or connector damaged?
If yes, make the necessary corrections or repairs. If the problem persists, proceed to the
next step.
If not, proceed to the next step.
2. Inspect the AC power source. Is the power source delivering the proper voltage?
If yes, proceed to the next step.
If not, make the necessary repairs. If the problem persists, proceed to the next step.
3. Replace the MPX200 blade.

System Fault LED is illuminated

The System Fault LED is illuminated when a fault exists in the MPX200 firmware or hardware. If
the System Fault LED is illuminated, check the Heartbeat LED for an error blink pattern and take
the necessary actions. For more information, see
