Power Supply Units (PSUs)
In the event of a power supply or PSU fan failure, replace the PSU using the following procedure.
CAUTION
: DO NOT REMOVE THE FAILED PSU until the new PSU has arrived and is ready to be
installed. Removing a PSU reduces air flow and cooling and can result in the system overheating.
CAUTION
: Computer components and disk drives are sensitive to electrostatic discharge (ESD).
Always ground any electrostatic charge from your person before touching components with your
hands or with any tools. Always use an anti-static wrist strap (one ships with each Nexsan Storage
System) while installing or performing maintenance on any Nexsan Storage System. See
on page 23 for detailed instructions.

To replace a PSU:
1. Determine which PSU or PSU fan has failed by examining the PSU status LEDs on each module. A red
LED indicates the failed module (see
on page 10). The
Home
page of the GUI also
tells you which module has failed (see the
Nexsan High-Density Storage User Guide
).
2. Remove the power cable from the power socket on the PSU where the failure has occurred.
3. Unbolt the front of the unit from the rack.
