CHAPTER 2 - Installation
Preparing for Installation
2.1.4 Fiber Optic Safety
Before installing the DX40 you should be aware that devices that employ laser technology, such as the fiber optical SFP ports and associated cabling, can be dangerous. Do not look directly into a fiber optic port or into the end of a fiber optic line. Doing so could cause injury to your eye or blindness. Always assume that there is laser activity in the line or port, even if the device is powered down. As a reminder, whenever this manual calls for the handling of fiber optic lines, those instructions will be accompanied by a “Laser Warning,” as follows:
LASER WARNING: DO NOT LOOK INTO A FIBER OPTIC CABLE OR PORT! These can produce invisible light that may do serious eye damage. Always assume that fiber optic cables or ports are actively radiating light energy.
2.1.5 Fiber Optic Handling
Contamination from dust, dirt, oils from the hands and other sources can impede the transmission and reception of optical signals through the optical fibers.When handling the optical connectors and fiber cables, follow these precautions to minimize the contamination of the connectors and ports:
•
•
•
•
Cover optical connectors and ports with dust caps when they are not in use. Do not touch fiber tips or the interior of optical ports when handling fiber cables and connectors.
Clean fiber optic connectors as described in Section 2.4.2.1, “Cleaning Connectors” prior to making any optical connection.
Clean optical ports as described in Section 2.4.2.2, “Cleaning Optical Ports” if contaminants or degraded performance are noted on the interface.
Fiber optic connectors should be cleaned after each use and optical ports should be cleaned if you notice contamination or degraded performance.
Fiber optic cables and connectors are fragile and can be easily broken through rough handling. When handling fiber optic media, take the following precautions:
•
•
•
Do not strike the fiber cable with tools.
Do not pinch, crimp, or compress the jacketing of the optical cable.
Do not use less than the minimum bend radius of 3 inches (7.62 cm) when routing or coiling cables.
2.1.6 External Connections
You can speed up the installation of the DX40 by having the following equipment and information on hand before beginning:
•
•
•
A supply of cables and connectors of the required types.
IP addresses for new devices and any existing devices you will be connecting to.
Your notes on naming conventions and end point information.
