3 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 switch specifications, see Specifications. NOTE: Install the switch into a rack or cabinet before installing any additional components such as cables or optics.
The cabinet must meet minimum size requirements. Airflow must be in accordance with the Electronic Industries Alliance (EIA) standard. Ensure that there is a minimum of 5 inches (12.7 cm) between the intake and exhaust vents and the cabinet wall. Rack mounting When you prepare your equipment rack, ensure that the rack is grounded. Ground the equipment rack to the same ground point the power service in your area uses. The ground path must be permanent.
5 inches (12.7 cm) apart. The fan speed varies based on internal temperature monitoring. The S4112–ON Series never intentionally turns off the fans. For more information, see Fans. Power To connect the switch to the applicable power source, use the appropriate power cable. An AC power cable is included with each PSU. When installing AC or DC switch, follow the requirements of the National Electrical Code ANSI/NFPA 70, where applicable.
4 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 ESD-preventive wrist or heel ground strap when handling the S4112–ON Series switch and its components.
2 Open the container or remove the container top. 3 Carefully remove the switch from the container and place it on a secure and clean surface. 4 Remove all packing material. 5 Inspect the product and accessories for damage. Ground cable NOTE: For an AC-powered switch, although the third conductor of the AC power cord provides a ground path, Dell EMC recommends grounding your switch with a dedicated ground wire.
• Reduced air flow—Do not compromise the amount of airflow required for safe operation of the equipment. Install the equipment in the rack so that the equipment constantly has the correct amount of airflow surrounding it. • Reliable earthing—Maintain reliable earthing of rack-mounted equipment. Pay particular attention to the supply connections other than the direct connections to the branch circuit, for example: use of power strips. • Do not mount the equipment with the fan panel facing downward.
Figure 14. Attach the dual-tray front to the 4-post rack front 7 Attach the rear dual-tray switch rails to the 4-post rack from the rear. Secure the dual tray to the rack using two user-supplied screws for each rack post. Figure 15. Attach the dual-tray rear to the 4-post rack rear 8 Tighten all mounting screws to securely mount the dual tray into the 4-post rack. Figure 16.
Figure 17. 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 18. Dual-tray stop feature 2 If you are installing two switches, insert the second switch in the open dual-tray slot. Switch removal Remove the switch from the dual tray from the front of the four-post rack. Push in the front switch latches according to the latch arrows and pull out the switch.
Figure 19. S4112-ON Series release latches Figure 20. S4112-ON Series release arrow Optics installation The S4112-ON Series (S4112F-ON adn S4112T-ON) switch has the following optic configurations: Table 7. S4112-ON Series optic configurations Platform S4112F-ON S4112T-ON Description • • 12 fixed 1/10GbE SFP+ optical ports 3 fixed 1/100GbE QSFP28 optical ports • 3 fixed 1/100GbE QSFP28 optical ports For a list of supported optics, see the S4112–ON Series data sheet at www.dell.
Optics removal Remove an optic by pushing the tab on the optic and sliding the optic from the port. When removing optics with direct attach cables (DACs) from the port, pull the release tab firmly and steadily. Before pulling the release tab, you may need to gently push the optic into the port to ensure that it is seated properly. Do not jerk or tug repeatedly on the tab. 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.
3 Label and remove all cables. 4 Remove the switch from the dual tray. Press the front switch latch according to the arrow and slide the switch forward. If you are using the PSUs in the replacement switch, remove them from the switch. 5 Unpack the new switch. For more information, see Unpack. 6 Confirm that the software version of the replacement switch is the same as the previously installed switch.
5 Power supplies The S4112–ON Series (S4112F-ON and S4112T-ON) switch ships with two AC or DC power supplies. The power supplies have two air-flow directions, normal and reverse. Normal is from the I/O-side to the PSU-side. Reverse is from the PSU-side to the I/O-side. CAUTION: To prevent electrical shock, ensure that the S4112-ON Series switch is grounded properly. If you do not ground your equipment correctly, excessive emissions may result.
Figure 23. S4112T–ON AC PSUs 1 AC PSUs Figure 24. S4112T–ON DC PSUs 1 DC PSUs The PSUs have an integrated fan that you cannot replace individually; if the fans integrated in a PSU fail, you must replace the entire PSU. You can replace the fan trays individually. For fan tray replacement procedures, see Fans. WARNING: Prevent exposure and contact with hazardous voltages. Do not attempt to operate this switch with the safety cover removed.
Figure 25. AC power cable clips PSU LEDs The single PSU LED is on the I/O-side of the switches. • Solid green—Input is OK. • Flashing yellow—There is a fault with the PSU. • Flashing green—System update. • Off—PSU is off. DC power connections Each DC PSU comes with a connector cable. One cable is provided for each DC PSU.
Figure 26. 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.
6 Fans The S4112–ON Series (S4112F-ON and S4112T-ON) switch comes from the factory with three integrated fans. The S4112–ON Series switch supports two airflow direction options—normal and reverse. • Airflow is from the I/O panel to the PSU—normal. • Airflow is from the PSU to the I/O panel—reverse.
7 Management ports Besides the 10/100/1000Base-T RJ-45 ports, the S4112-ON Series (S4112F-ON and S4112T-ON) switch provides several ports for management and storage. NOTE: The output examples in this section are for reference only. Your output may vary.
