2 Site preparations The S4112-ON Series (S4112F-ON and S4112T-ON) switch is suitable for installation as part of a common bond network (CBN). You can install the switch in: • • • Network telecommunication facilities Data centers Other locations where the National Electric Code (NEC) applies For more information about the S4112-ON Series switch specifications, see Specifications. NOTE: Install the switch into a rack or cabinet before installing any optional components.
• Environmental—switch location—continuous temperature range is from 5° to 40°C (50° to 104°F). • Operating humidity is from 5 to 85 percent non-condensing, continuous. • In a dry, clean, well-ventilated, and temperature-controlled room, away from heat sources such as hot cooling vents or direct sunlight. • Away from sources of severe electromagnetic noise. • Positioned in a rack or cabinet, or on a desktop with adequate space in the front, back, and sides for proper ventilation and access.
Fans and airflow Fan installation is done as part of the factory install based on stock keeping unit (SKU) type.
Storing components If you do not install your S4112-ON Series switch and components immediately, properly store the switch and all optional components following these guidelines: • Storage location temperature must remain constant. The storage range is from -40° to 65°C (-40° to 149°F). • Store on a dry surface or floor, away from direct sunlight, heat, and air conditioning ducts. • Store in a dust-free environment. NOTE: ESD damage can occur when components are mishandled.
3 S4112-ON Series Installation To install the S4112-ON Series (S4112F-ON and S4112T-ON) switch, complete the installation procedures in the order presented in this section. Always handle the switch and its components with care. Avoid dropping the switch or any field replaceable units (FRUs). NOTE: ESD damage can occur if components are mishandled. Always wear an ESDpreventive wrist or heel ground strap when handling the switch and its components.
• One RJ-45 to DB-9 female cable • AC power: two country- and region-specific AC power cords • DC power: two DC connectors • Ground lug kit (included in the accessories box) • S4112-ON Series Setup Guide • Safety and Regulatory Information • Warranty and Support Information 1 Place the container on a clean, flat surface and cut all straps securing the container. 2 Open the container or remove the container top.
NOTE: Coat the one-hole lug with an anti-oxidant compound before crimping. Also, bring any unplated mating surfaces to a shiny finish and coat with an anti-oxidant before mating. Plated mating surfaces must be clean and free from contamination. NOTE: The rack installation ears are not suitable for grounding. Before you install the switch into the dual-tray: 1 Cut the ground cable (not included) to the desired length. The cable length must facilitate proper operation of the fault interrupt circuits.
power ratings do not exceed the circuit capabilities. Overloaded power sources and extension cords present fire and shock hazards. • Elevated ambient temperature—If you install the switch in a closed rack assembly, the operating temperature of the rack environment may be greater than the room ambient temperature. Use care not to exceed the 45°C (113°F) maximum ambient temperature of the switch. • Reduced air flow—Do not compromise the amount of airflow required for safe operation of the equipment.

Secure the dual tray to the rack using two user-supplied screws for each rack post. Figure 5. Attach the dual-tray rear to the four-post rack rear 8 Tighten all mounting screws to securely mount the dual tray into the four-post rack.
Figure 6. Secure the dual-tray in the four-post rack Switch installation Install one or two half-RU switches in the four-post rack-mounted dual tray. 1 Install one switch into either dual-tray slot from the front. Figure 7. Install an S4112-ON Series switch The switch is fully inserted when it hits the stop feature on the dual tray. The front switch latch snaps the switch into place.
Figure 8. Dual-tray stop feature 2 If you are installing two switches, insert the second switch in the open dual-tray slot. Switch removal 1 Remove a switch from the dual tray from the front of the four-post rack. 2 Push the front switch latches according to the latch arrows and pull out the switch. Figure 9.

Figure 11. DC power connector and wiring block 1 Wiring block 3 PSU connector 2 Power connector 1 Strip a 1/2 inch section of insulation from each of the power connector’s wires, as shown. 2 Insert each of the power connector’s bare wire lengths into the wiring block. The blue wire is -48V, the black wire is the positive return, and the yellow/green wire is the ground wire, as shown. 3 Use a flat-blade screwdriver to tighten the screws that secures the bare wires into the wiring block.
4 Secure the site’s DC power source wires to the other side of the wiring block, see steps 1 and 3. WARNING: Do not cross the wires. 5 Insert the DC power connector into the power socket of the DC PSU. Ensure that the connector pins firmly seat and you hear the click of the power connector’s left and right levered clamps lock into place. WARNING: Never try to force the power connector into or out of the DC PSU power socket.
Switch power-up Supply power to the S4112-ON Series (S4112F-ON and S4112T-ON) switch after you mount it in a rack or cabinet. Reinspect your switch before power up.
