Chapter 8 Troubleshooting Your Array 8-5

8.1.4 Power Supply Sensors

Each SANnet II 200 FC, SATA, and SATA SE array has two fully redundant power

supplies, with load sharing capabilities. The sensors monitor the voltage, temperature,

and fan units in each power supply.

8.2 Silencing Audible Alarms

An audible alarm indicates that either a component in the array has failed or a specific

controller event has occurred. Error conditions and controller events are reported by

event messages and event logs. Component failures are also indicated by LED activity

on the array.
