B Diagnostics and troubleshooting
Diagnostic information about the mpx100/100b is available through the chassis LEDs and the port LEDs.
Diagnostic information is also available through the HP StorageWorks mpx Manager and CLI event logs
and error displays. This section describes the following types of diagnostics:
• Chassis diagnostics , page 173
• Troubleshooting LUN presentation from the EVA to the iSCSI initiator , page 175

Input Power LED is extinguished
The Input Power LED is illuminated when the mpx100/100b logic circuitry is receiving proper voltages. If
the Input Power LED is not illuminated:
1. Inspect power cord and connectors. Is the cord unplugged? Is the cord or connector damaged?
• If yes, make necessary corrections or repairs. If the condition remains, continue with the
next step.
• If not, continue with the next step.
2. Inspect AC power source. Is the power source delivering the proper voltage?
• If yes, continue with the next step.
• If not, make the necessary repairs. If the condition remains, continue with the next step.
3. Replace the mpx100/100b.
System Alert LED is illuminated
The System Fault LED is illuminated when a fault exists in the mpx100/100b firmware or hardware. If the
System Fault LED is illuminated, check the Heartbeat LED for an error blink pattern and take necessary
actions. See “ Heartbeat LED blink patterns ” on page 174 for more information.
