4.5 Dealing with Hardware Faults
Ensure that you have obtained a replacement module of the same type
before
removing any faulty
module.
Warning
If the Storage Scaler 6000 subsystem is powered up and you remove any module, replace it
immediately. If the subsystem is used with modules or module blanks 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 equal or greater capacity.
• All the supplied plug-in PCMs, electronics modules, and blank modules must be in place for the air
to flow correctly around the cabinet.
4.6 Replacing a Module
Warning
Whenever replacing a module NEVER leave an EMPTY bay in the rear of the enclosure, obtain a
replacement before removing the problem part.
Please refer to
Chapter 2
, ”Getting Started”
for information on the initial installation of the plug-in modules
in the Storage Scaler 6000 enclosure.
Warning
Observe all conventional ESD precautions when handling Storage Scaler 6000 modules and
components. Avoid contact with Backplane components and module connectors, etc.
4.6.1 Power Cooling Modules
Warning
Do not remove covers from the Power Cooling module (PCM). There is a danger of electric shock.
Return the PCM to your supplier for repair.
Warning
To ensure your system has warning of a power failure please disconnect the power from the
power supply, by either the switch (where present) or by physically removing the power source,
prior to removing the PCM from the enclosure/shelf. Do not remove the faulty PCM unless you
have a replacement unit of the correct type ready for insertion. The system must not be run
without all units in place.
If a power supply unit or its fan is faulty, you must replace the whole PCM. You must not take any longer
than 5 minutes to replace this unit to prevent the enclosure from over-heating.
To remove an AC PCM/Cooling Module- Handle Model:
If a power supply unit or its fan is faulty, you must replace the whole PCM/Cooling module.
As there should always be two PCMs installed, you can continue working while replacing the faulty
module.
1
Make sure you identify the faulty PCM correctly from the two modules installed.
2
Lift latch which secures the power supply cord.
3
Switch off and disconnect the power supply cord.
