ETEP Installation Guide 65
4 Maintenance
Preventative Maintenance
Periodically perform maintenance on your ETEP. Keep components free of dust and other particulate
matter. Examine cables for damage and ensure that airflow requirements have been met. On ETEP
models that have fans, check the fans for reduced airflow caused by dust build-up and clean as necessary.
No special maintenance is required.
The ETEP is housed in a tamper evident chassis. Periodically check the chassis for evidence of
tampering. Items to look for include stripped screws and damage to the tamper-evident seal. The tamper-
evident seal is located on the rear panel;
The frequency of a physical inspection depends on the value of the intellectual property being protected
and the security of the environment in which the ETEP is located. For example, a locked equipment
closet is more secure than an open server room. At a minimum, it is recommended that the unit’s physical
integrity be checked on a monthly basis.
CAUTION
The ETEP does not contain any field-replaceable internal parts. Do not remove the unit’s cover for any
reason. Removing the cover will zeroize the ETEP, returning it to its factory default state. All configuration
data and keys are destroyed during the zeroization process. The cover is to be removed only by
authorized service personnel. Unauthorized cover removal voids the product warranty.
CAUTION
Disconnect all power cords before servicing.
What To Do If an Appliance Fails
Most ETEP models do not contain any field-replaceable parts. If you experience an appliance failure,
contact Customer Support for a replacement ETEP and throughput license.
The ET1000A and ET10000A have field-replaceable power supplies. Contact Customer Support to obtain
a replacement power supply in the event of a failure. See “Replacing a Power Supply” on page 66 for
removal and installation instructions.
