Troubleshooting and Problem Solving
Dealing with Hardware Faults
Ensure that you have obtained a replacement module of the same type before removing any faulty
module.
!
WARNING
If your SR1202 enclosure is powered up and you remove any module, replace it immediately. If the
enclosure is used with plug-in modules, dummy carriers or blank modules 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 drive bays must be fitted with a Drive Carrier or Dummy Carrier module in order to maintain
abalanced air flow.
• All of the supplied plug-in power supply units, electronics modules, dummy carriers and blank
modules must be in place for the air to flow correctly around the cabinet.
Continuous Operation During Replacement
Depending on how the SR1202 enclosure is set up, if a disk unit fails, it can normally be replaced
without interrupting the use of the system.
In addition, each enclosure contains two Power Supply modules, either of which can maintain power
and cooling to the subsystem while the other is replaced.
NOTE
The PSU replacement time must be as short as possible as the SR1202 enclosure is designed to
operate with two PSUs installed.
!
IMPORTANT
The fans within the Cooling module are not user replaceable, in the event of a cooling fan failure the
complete Cooling module must be replaced.
Ops Panel
!
IMPORTANT
The Ops Panel is an integral part of the enclosure assembly and can only be replaced with a replacement
enclosure. The enclosure should only be replaced by trained personnel.
Replacing a Module
!
WARNING
Whenever replacing a module NEVER leave an EMPTY space in the rear of the enclosure, obtain a
replacement before removing the problem part.
Please refer to Chapter 3, ”Getting Started” for information on the initial installation of the plug-in
modules in the SR1202 enclosure.
!
WARNING
Observe all conventional ESD precautions when handling SR1202 modules andcomponents. Avoid
contact with Backplane components and module connectors, etc.
