4.6 FC-AL Drive Carrier Module Faults
Disk drive status is monitored by a Green LED and an Amber LED mounted on the front of each Drive Carrier
Module, providing the following indications:
4.7 Dealing with Hardware Faults
Ensure that you have obtained a replacement module of the same type before removing any faulty module.
Warning If the SS-1200-FCAL subsystem is powered up and you remove any module, replace it
immediately. If the subsystem is used with modules or blanking plates missing for more than a
few minutes, the Enclosure can overheat, causing power failure and data loss. Such use will
invalidate the warranty.
• Replace a faulty drive with a drive of the same type and capacity.
• All drive bays must be fitted with either a Drive Carrier Module or a front dummy fascia in order to maintain
a balanced air flow.
• All the supplied plug-in power supply units, electronics modules and Blank plates must be in place for the air
to flow correctly around the cabinet.
4.8 Continuous Operation During Replacement
Depending on how the subsystem is set up, if a disk unit fails, it can normally be replaced without interrupting the
use of the system.
In addition, each enclosure can contain one, two or three power supply units, any of which can maintain power and
cooling to the subsystem while one of the others is replaced.
4.9 Replacing a Module
Please refer to Chapter 2, ”” for information on the initial installation of the plug-in modules in the SS-1200-FCAL
enclosure.
Warning Observe all conventional ESD precautions when handling SS-1200-FCAL modules and
components. Avoid contact with Backplane components and module connectors, etc.
