Returning your faulty fan tray module
A Takeback and Recycle program is provided in compliance with the WEEE (Waste
Electrical and Electronic Equipment) directive for the recycling of electronic
equipment.
The program enables you to return an obsolete or excess nShield-branded product,
which is then disposed of in an environmentally safe manner. For further information
or to arrange the safe disposal of your faulty fan tray module, e-mail

Entrust nShield® Connect Fan Tray Module
The nShield Connect fan tray module contains the main cooling fans and the backup
batteries for the tamper detection functionality. The fan tray module is outside the
security boundary, and can be safely replaced without activating a tamper event. Fan
tray modules must not be modified in any way. Faulty fan tray modules must be
returned for recycling, see Returning your faulty fan tray module in this document.
Note: The backup batteries on the fan tray module provide reserve capacity (a
guaranteed minimum of 3 years) for the tamper detection functionality when
the nShield Connect is in an unpowered state.
If you receive any of the following error messages, accompanied by the orange
warning LED, follow the related action in the table below:
Error message Action
Single fan fail Contact Support
Many fans fail Replace fan tray
Battery power low Replace fan tray
If the error message is Single fan fail, the nShield Connect can continue operating
under the specified operating environment. Although you are advised to contact
Support, the limited nature of such a failure means you can replace the fan tray module
at your convenience.
If the error message is either Many fans fail or Battery power low, you must replace
the fan tray module immediately.
Before you begin
Before you begin the replacement procedure, press the power button on the front
panel to power down the nShield Connect. The unit is now in standby mode. Removing
the fan tray module without powering down causes the unit to shut down to prevent
damage from overheating.
We recommend that you keep the unit powered in standby mode when replacing the
fan tray module. This provides auxiliary power to feed the tamper circuitry and allows
you to replace the fan tray at your convenience. However, if you do remove mains
power, you must install the replacement fan tray within one hour to ensure that a
tamper event is not activated.
Note: Tamper detection functionality remains operational for at least an hour after
the fan tray module is removed for replacement. Removing and replacing the
fan tray cover does not affect the nShield Connect or the tamper detection
functionality.
For more information about the physical security measures implemented on the
nShield Connect, see the nShield Connect User Guide.
