Troubleshooting and
Problem Solving

4.1 Overview

The Storage Scaler 6000 Drive Enclosure includes an Enclosure Services Processor and associated

monitoring and control logic to enable it to diagnose problems within the enclosure’s power, cooling, and
drive systems.

The sensors for power and cooling conditions are housed within the PCMs. Each unit is independently

monitored.

4.2 Initial Start-up Problems

4.2.1 Faulty Cords

First check that you have wired up the subsystem correctly. If:

• cords are missing or damaged,
• plugs are incorrect,

• cords are too short,

Call your supplier for a replacement.

4.2.2 Alarm Sounds On Power Up

The Audible Alarm sounds anytime the top cover is open. The alarm mutes automatically once the cover
is closed.

4.2.3 Green “Signal Good” LED on I/O Module Not Lit

Check to ensure that the cables have not been reversed during installation.
