Section 3: Installation Considerations
WARNING! Fiber cables transmit invisible infrared light. To avoid eye damage or blindness,
never look directly into fibers or connectors.
CAUTION! These instructions presume you have verified the Amphenol Network Solutions
equipment being installed is compatible with the rest of the system including power, ground,
circuit protection, signal characteristics, equipment from other vendors, and local codes or
ordinances.
ALERT! This product must be installed and maintained only by qualified technicians.
ALERT! Install this system according to company requirements. It is recommended you install
the system in a Restricted Access Location (RAL) where access is limited using tool, lock and
key, or other means of security and be controlled by the authority responsible for the location.
ALERT! Prior to chassis installation, ensure there is enough space in front and rear to access
cabling.
ALERT! Only use components and crimping tools approved by agencies or certifying bodies
recognized in your country or region, such as Underwriter’s Laboratories (UL), TIA, etc.
