Chapter 7. Device Failure and Replacement

Whether the red LED is flashing or the syslog is filling up with cryptic messages, a hardware failure is never a day at the beach. The goal of this chapter is to provide a guide for identifying and remedying device failures. We begin with a discussion of supported devices before proceeding with a discussion of how to look for errors. We then discuss how to identify a failed device. Finally, we consider replacements and alternative options to remedy the problem.
