Introduction
1.5.3 Supported Fiber Optic Cables
Follow these recommendations for copper data cabling in high electrical noise
environments:
• Data cable lengths should be as short as possible, preferably 3 m (10
ft) in length. Copper data cables should not be used for inter-building
communications.
• Power and data cables should not be run in parallel for long distances, and
should be installed in separate conduits. Power and data cables should intersect
at 90° angles when necessary to reduce inductive coupling.
• Shielded/screened cabling can be used when required. Care should be taken to
avoid the creation of ground loops with shielded cabling.

Tamper-Evident Security Seals
In compliance with the security requirements of the Federal Information Processing
Standards (FIPS140-2), FIPS-compliant tamper-evident security seals are applied
to potential access points on this device. Security seals provide evidence of
unauthorized tampering or removal of components.
NOTICE
Worn, damaged or missing seals must be replaced immediately.
Replacement seals are available for purchase from Siemens. For more information,
contact a Siemens Sales representative.
There are three ways to determine if a security seal has been tampered with:
• The seal is cut or torn
• A pattern is left on the device when the top layer of the seal is removed
