Cooling Requirements; Physical Location Considerations - Entrust nShield nToken v12.40 Installation Manual

Cooling requirements

Cooling requirements
Adequate cooling of the module is essential for trouble-free operation and a long operational life.
During operation you can use the supplied utility to check the actual and maximum
stattree
temperature of the module. It is advised to do this directly after installing the module in its normal
working environment. Monitor the temperature of the module over its first few days of operation. If the
module exceeds the safe operating temperature, it stops operating and displays the error
SOS-T
message on the Status LED (see Status indicators on page 26).

Physical location considerations

nCipher nShield HSMs are certified to NIST FIPS 140-2 level 2 and 3. In addition to the intrinsic
protection provided by an nShield HSM, customers must exercise due diligence to ensure that the
environment within which the nShield HSMs are deployed is configured properly and is regularly
examined as part of a comprehensive risk mitigation program to assess both logical and physical
threats. Applications running in the environment shall be authenticated to ensure their legitimacy and
to thwart possible proliferation of malware that could infiltrate these as they access the HSMs'
cryptographic services. The deployed environment must adopt 'defense in depth' measures and
carefully consider the physical location to prevent detection of electromagnetic emanations that might
otherwise inadvertently disclose cryptographic material.
