Admonishments Important safety admonishments are used throughout this manual to warn of possible hazards to persons or equipment. An admonishment identifies a possible hazard and then explains what may happen if the hazard is not avoided. The admonishments — in the form of Dangers, Warnings, and Cautions — must be followed at all times. These warnings are flagged by use of the triangular alert icon (seen below), and are listed in descending order of severity of injury or damage and likelihood of occurrence. Danger: Danger is used to indicate the presence of a hazard that will cause severe personal injury, death, or substantial property damage if the hazard is not avoided. Warning: Warning is used to indicate the presence of a hazard that can cause severe personal injury, death, or substantial property damage if the hazard is not avoided. Caution: Caution is used to indicate the presence of a hazard that will or can cause minor personal injury or property damage if the hazard is not avoided.

INSTALLATION Warning: Never install chassis in a wet location or during a lightning storm. When installing or modifying communication lines, disconnect lines at the network interface before working with uninsulated lines or terminals. Equipment must be installed after Central Office lightning and grounding protection. 1. Install the Chassis in an ETSI cabinet as shown in Figure 3. NOTE: INSTALL AN M6-10 CAGE NUT (PROVIDED) INTO RESPECTIVE MOUNTING SLOT LOCATIONS IN RAIL
INSERT ONE END OF CAGE NUT INTO SLOT IN RAIL
PUSH OTHER END INTO SLOT
NOTE: IT IS RECOMMENDED TO INSTALL THE CHASSIS ABOVE THE CORRESPONDING DSLAM.

3. Install Circuit Modules as shown in Figure 5 and Figure 6. Note: The make-before-break connections on the chassis backplane allow for insertion or removal of circuit modules without interrupting POTS service. Caution: Observe precautions for handling electrostatic sensitive devices such as printed circuit boards.

4.1 LINE and POTS Cables Figure 8 shows the procedure for routing LINE (from MDF) and POTS (to MDF) cables. The LINE cables are shown in light gray and the POTS cables are shown in dark gray for clarity. Caution: Suggested connector mating cable fasteners are pan-head captive screws overall length of 0.75 inch (19 mm) with no more than 0.25 inches of threads (6.35 mm). If connector mating cable screws are longer than 0.75 inch (19 mm) with more than 0.25 inches of threads (6.35 mm), screws will interfere with the backplane and pull insulator away from the connector. NOTE: LINE CIRCUITS ARE ROUTED FROM THE MDF, POTS CIRCUITS (VOICE ONLY) ARE ROUTED BACK TO THE MDF

4.2 DATA Cables Figure 9 shows the procedure for routing DATA cables from the splitter chassis to the DSLAM. Caution: Suggested connector mating cable fasteners are pan-head captive screws overall length of 0.75 inch (19 mm) with no more than 0.25 inches of threads (6.35 mm). If connector mating cable screws are longer than 0.75 inch (19 mm) with more than 0.25 inches of threads (6.35 mm), screws will interfere with the backplane and pull insulator away from the connector.
