FaxPress Enterprise Redundant Getting Started Guide
Replacing Redundant Components
The FaxPress Enterprise Redundant's hard disk drives, system fans and power supply modules are relatively
easy to remove and replace in case of failure or malfunction. As the redundant designation implies, each
component has an exact duplicate running in its place, providing non-stop functionality in case one of them
malfunctions. In the rare event that this occurs the FaxPress Enterprise Redundant will automatically and
transparently transfer the workload to the functioning module, providing administrators enough time to
replace the faulty component(s). There is no need to power down the FaxPress Enterprise Redundant to
replace the faulty component(s).
Replacing a Hard Disk Module
To remove a failed hard disk drive, open the latch and use it to pull out the hard disk module. This can be
done while the system is on and processing faxes as long as one hard disk module is present and operational.
Put a replacement hard disk module into the failed hard disk slot. Push in the module until it is flush with the
other hard disk module and the latch has almost completely snapped back in. Press the latch completely into
the module.
Replacing a System Fan Module
Replacing a fan can be done while the system is on and processing faxes. Both fan modules can be removed
at the same time, as long as failed modules are replaced immediately, and the temperature of the system
components remains stable.
To replace a failed system fan module, pull on the latch until the fan module is completely out. Align the new,
replacement fan module with the chassis and push straight down on the middle of the module until it is flush
into the chassis. Replace and reseal the chassis.
Replacing a Power Supply Module
Under normal conditions with both power supply modules operational, the power supply's status LED will
be solid green. When a power supply module fails or is turned off, the power supply chassis will produce a
loud beep and cause the status LED to blink. Pressing the alarm cutoff switch will silence the loud beep, but
the status LED will continue to blink until both power supply units are on and operational.
To remove the power supply module, bring the module handle down to facilitate the removal of the power
supply module. This might require a moderate amount of force. Slide the black latch in towards the module
handle and pull the module out by the handle at the same time. This can be done while the system is on and
processing faxes as long as one power supply module is present and operational.
