11. nShield Connect maintenance
The nShield Connect contains only two user-replaceable parts:
•
The PSUs
•
The fan tray module
Replacing a PSU or fan tray module does not affect FIPS 140-2 validations for the nShield
Connect, or result in a tamper event. However, in the very rare event that a PSU or fan
tray module requires replacement, contact Support before carrying out the replacement
procedure.
Do not allow a fan tray to be removed from the nShield Connect for
longer than 30 minutes, otherwise a tamper event will occur.
For more information about replacing either a PSU or the fan tray module, see the
Installation Sheet that accompanies the replacement part.
Breaking the security seal or dismantling the nShield Connect voids
your warranty cover, and any existing maintenance and support
agreements.
11.1. Flash testing the module
The module is designed to comply with IEC/EN 60950-1 but should be tested only by
trained safety professionals. Because the module is fitted with radio frequency
interference suppressors, it is recommended that only a DC test be performed.
Repeated application of the flash test can damage safety insulation.
