2.8 EMI/EMC
The StorageTek T10000D Tape Drive conforms to the EMI/EMC requirements
specified by 47 Code of Federal Regulations, Part 15, Subpart B, Unintentional
Radiators, Digital Devices, Class A (business use).
2.9 Self-Tests
The StorageTek T10000D Tape Drive performs the required Integrity Test and
Power-On Self-Tests (POSTs) during initial power-up. On-demand self-tests can
be performed by the “IPL” service available to the CO or by cycling the power of
the module. The module executes conditional self-tests during normal operation
whenever a new random number is generated, asymmetric key pairs are
generated, or whenever new firmware is loaded. The following sections describe
the power-up and conditional self-tests that are run by the module in each
Approved mode. All test run without requiring operator intervention.
2.9.1 Integrity Tests
An integrity test is the first operation performed by the StorageTek T10000D
Tape Drive after power has been supplied. The module performs a 32-bit CRC
53
on the firmware and hardware/FPGA images as its approved integrity technique.
Data output is not available while the integrity test is being performed. If the test
passes, the module will continue on to perform the required Known Answer Tests
(KATs) on its cryptographic algorithms. If the firmware integrity test fails, the
module will remain in its initial boot state and create an unencrypted dump file
54
.
The CO will be required to reboot the module in order to resolve the error.
2.9.2 Power-On Self-Tests
POSTs are performed by the ETD when power is applied to the module and after
the integrity test has passed. Data output is not available while the POSTs are
being performed. After the POSTs successfully complete, the module will begin
normal operation. Normal operation may be in one of the Approve modes or in
the Mixed mode. The operational status of the module is determined when the
module first boots. If any of the POSTs fail, then the ETD will create an
unencrypted dump file and then continue to reboot. Otherwise, the module
indicates that all self-tests have passed by moving to a normal operational state.
The following POSTs are performed by the module during every boot-up,
regardless of current operational mode:

CRC – Cyclic Redundancy Check

When operating in the Permanent Encryption or Encryption Enabled Modes, unencrypted data dumps shall be deleted by the
CO after their creation
