Thermal considerations
Thermal sensors in the 5U84 enclosure and its components monitor the thermal health of the storage system.
NOTE:
• Exceeding the limits of critical values will activate the over-temperature alarm.
• For information about 5U84 enclosure alarm notification, see 5U alarm conditions .
CLI port connections
ME4 Series Storage System controllers feature a CLI port employing a 3.5mm stereo plug and a mini-USB Type B form factor. For more
information about connecting a serial cable, see
Appendix A of this manual.
Fault isolation methodology
Dell EMC ME4 Series Storage Systems provide many ways to isolate faults. This section presents the basic methodology used to locate
faults within a storage system, and to identify the pertinent CRUs affected.
Use the ME Storage Manager to configure and provision the system upon completing the hardware installation. As part of this process,
configure and enable event notification so the system will notify you when a problem occurs that is at or above the configured severity (see
the topic about configuring event notification within the
Dell EMC ME4 Series Storage System Administrator’s Guide ). With event
notification configured and enabled, you can follow the recommended actions in the notification message to resolve the problem, as further
discussed in the options presented in the following section.
Fault isolation methodology basic steps
Following is a summary of the basic steps used to perform fault isolation and troubleshooting:
• Gather fault information, including using system LEDs as described in Gather fault information
• Determine where in the system the fault is occurring as described in Determine where the fault is occurring .
• Review event logs as described in Review the event logs .
• If required, isolate the fault to a data path component or configuration as described in Review the event logs .
