Cisco 7609-S User Guide - Page 13

Caution: Due to decreased airflow when using the opacity shield, which is required for FIPS 140-2 validation, short-term operation as specified by GR-63-CORE at 55oC is impacted. Short-term operation requirements will only be met at 40 oC. Without the opacity shield installed, the system will meet the short-term operations requirements at 55 oC. Caution: We recommend that you change the opacity shield every three months to prevent dust build-up and the possibility of overheating the chassis. If the environment is especially dusty, inspect and replace the opacity shield more often. Note: If you need to remove the 7606-S chassis from the rack, you must first remove the opacity shield. With the opacity shield installed, the chassis is too wide to slide out of the rack. Figure 4 - Installing the Opacity Shield on the Cisco 7606-S Router The 7609-S does not require any opacity shields. 2.4.2 Tamper Evidence Once the module has been configured to meet overall FIPS 140-2 Level 2 requirements, the module cannot be accessed without signs of tampering. The CO shall inspect for signs of tampering periodically. To seal the system, apply serialized tamper-evidence labels as depicted in the figures below. © Copyright 2011 Cisco Systems, Inc. 13 This document may be freely reproduced and distributed whole and intact including this Copyright Notice.
