7.11 Galaxy 65 Subsystem Problems
Problem: The Storage Manager module’s STATUS LED does not turn on.
Check that the SM module is properly seated in the slot and the handles are closed and locked. Check
for events in SAM and the RS-232 interface (Disk Array Administrator) for power-on initialization and
diagnostics errors.
Problem: The Galaxy 65 Subsystem reports an SDRAM memory error.
Contact your supplier.
7.12 Replacing a Module
Please refer to the Galaxy 65 Getting Started Manual (P/N 44521-01A) for information on the initial
installation of the plug-in modules in the Galaxy 65 enclosure.
Warning Observe all conventional ESD precautions when handling Galaxy 65 modules and components.
Avoid contact with Backplane components and module connectors, etc.
7.12.1 Power Supply/Cooling Modules
Warning Do not remove covers from the power supply unit. Danger of electric shock inside. Return the PSU
to your supplier for repair.
7.12.1.1 Removing a PSU Module
Warning Do not remove the faulty Power Supply/Cooling module unless you have a replacement unit of the
correct type ready for insertion.
If a power supply unit or its fan is faulty, you must replace the whole Power Supply/Cooling module.
As there should always be two power supply units installed, you can continue working while replacing the
faulty module.
1 Make sure you identify the faulty Power Supply/Cooling module correctly, from the two modules installed,
2 Switch off and disconnect the power supply cord.
3 Squeeze the two latches on the PSU handle together ( Figure 7–2 ) and open the handle to cam the PSU
out of the enclosure ( Figure 7–3 ).
4 Grip the handle and withdraw the PSU ( Figure 7–4 ).
7.12.1.2 Inserting the Module
1 Check for damage, especially to the rear connector on the PSU.
Caution Handle the module carefully and avoid damaging the connector pins. Do not install the module if any pins
appear to be bent.
