Chapter 2

Interpreting LEDs

About this chapter

This chapter describes the basic startup sequence and interpreting LEDs on your system for basic monitoring of the system.

Types of LEDs

Two sets of LEDs provide you with basic information about how your system is running. These sets give high-level device status at a glance, along with network activity:

LEDs visible on the front of your appliance with the bezel in place
Front Panel
LEDs visible on the back of your appliance

Using cheat sheets for quick reference

Your system is shipped with a cheat sheet located at the bottom of the chassis.

Check LEDs

Check all system LEDs to determine whether any components are not functioning properly. The following illustration is a replica of the part of the cheat sheet that shows LED locations and explanations.

FRU Map

Use the FRU map to identify Field-Replaceable Units in your system.

Note
FRU procedures are documented in flyers shipped with the component. You can also go to the Hardware Information Library for FRU documentation at http://now.netapp.com.
