Troubleshooting Flowcharts

This section provides flowcharts to illustrate common troubleshooting methods.

The flowcharts included in this section are:

■

 “Power Supply and Fan Module” on page 7-7

■

 “Drive LEDs” on page 7-9

■

 “Front-Panel LEDs” on page 7-14

■

 “I/O Controller Module” on page 7-19

For the JBOD and expansion unit flowchart, see  “Troubleshooting SANnet II 200 
SCSI JBOD Arrays” on page B-13. 

For overview information about LEDs, see Chapter 5.

For information about replacing modules, refer to the 

SANnet II Family FRU 

Installation Guide

.

Caution – 

Whenever you are troubleshooting and replacing components, there is an 

increased possibility of data loss. To prevent any possible data loss, back up user data 
to another storage device prior to troubleshooting your array. 

7.7.1

Power Supply and Fan Module 

The following flowchart provides troubleshooting procedures for the power supply and 
fan module.
