NOTE: Install the S4048–ON switch into a rack or cabinet before installing any optional components.
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. Switch ground Dell EMC recommends you ground you switch. Use the S4048–ON in a common bond network (CBN). Connect the grounding cables as described in Install the S4048–ON. Fans and airflow The S4048–ON fans support two airflow options.
NOTE: ESD damage can occur when components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when handling the S4048–ON and its accessories. After you remove the original packaging, place the S4048–ON and its components on an anti-static surface.
4 NEBS compliance For your switch to be network equipment building system (NEBS) compliant, you must follow the instructions detailed in this section. To be NEBS compliant, orient your switch in the rack so that the air inlet is from the front aisle and the air exhaust is to the back aisle.
5 S4048–ON installation To install the S4048–ON switch, Dell EMC recommends completing the installation procedures in the order presented in this chapter. Always handle the S4048–ON and its components with care. Avoid dropping the switch or its 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 S4048–ON and its components.
NOTE: The illustrations in this document are not intended to represent a specific switch. NOTE: Do not the use the mounted Ready-Rails as a shelf or a workplace. Rack mount safety considerations ● Rack loading—Overloading or uneven loading of racks may result in shelf or rack failure, causing damage to the equipment and possible personal injury. Stabilize racks in a permanent location before loading begins. Mount the components beginning at the bottom of the rack, then work to the top.
Two-post flush-mount configuration CAUTION: Your switch is not NEBS Earthquake Z4-compliant if you use this installation method. 1. For this configuration, remove the latch castings from the front side of each ReadyRails assembly, item 1. To remove the two screws from each front flange ear on the switch side of the rail and remove each casting, use a Torx screwdriver. Retain the castings for future rack requirements. It is not necessary to remove the rear flange castings. Figure 7.
Figure 8. Two-post center-mount configuration 2. Slide the back bracket towards the post and secure it to the post flange with two user-supplied screws, item 2. 3. Repeat this procedure for the second rail. Four-post threaded configuration CAUTION: To be NEBS Earthquake Z4-compliant, you must remove the tool-less latch castings described in Step 1. 1. For this configuration, remove the latch castings from each end of the ReadyRails assemblies.
Figure 9. Four-post threaded configuration 2. For each rail, attach the front and rear flanges to the post flanges with two user-supplied screws at each end, item 2. S4048-ON installation You can mount the switch in the 1U front-rack or 1U flush and center two-post configurations. The following is an example of a front-rack configuration: For the 1U flush and center two-post configurations, slide the switch into the rails in the same manner as the four-post configurations.
Figure 10. Switch rails attachment 2. After you have installed both switch rails, line them up on the previously mounted Ready-Rails and slide the switch in until it is flush with front of rack. About 3 inches before you fully insert your switch, the rail locking feature engages to keep the switch from inadvertently sliding out of the rack and falling. NOTE: Do not the use the mounted Ready-Rails as a shelf or a workplace. Figure 11.
Ground cable Dell EMC recommends grounding your switch. To attach the ground cable to the chassis, use a single M4x0.7 screw. The cable itself is not included with the S4048–ON. To properly ground the chassis, Dell EMC recommends using a 6 AWG one-hole lug, #10 hole size, 63" spacing, not included in shipping. The one-hole lug must be a UL recognized, crimp-type lug. CAUTION: Grounding conductors must be made of copper. Do not use aluminum conductors.
Switch power-up Supply power to the S4048–ON after it is mounted in a rack or cabinet. Dell EMC recommends re-inspecting your switch before powering up. Verify the following: ● The equipment is properly secured to the rack and properly grounded, optional. ● The equipment rack is properly mounted and grounded, optional. ● The ambient temperature around the unit—which may be higher than the room temperature, is within the limits specified for the S4048–ON. For more information, see Specifications.
6 Power supplies The S4048–ON ships with one AC power supply. Dell EMC recommends purchasing a second power supply. The S4048–ON supports AC power supplies with 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. Two PSUs are required for full redundancy, but the switch can operate with a single PSU. The PSUs are field replaceable.
CAUTION: Remove the power cable from the PSU prior to removing the PSU. Also, do not connect the power cable before you insert the PSU in the chassis. NOTE: To comply with the GR-1089 Lightning Criteria for Equipment Interfacing with AC Power Ports, use an external surge protection device (SPD) at the AC input of the router. AC power supply installation NOTE: The PSU slides into the slot smoothly. Do not force a PSU into a slot as this action may damage the PSU or the S4048–ON chassis.
AC power supply replacement CAUTION: Disconnect the power cord before removing the power supplies. Also, disconnect all power cords before servicing. NOTE: The PSU slides into the slot smoothly. Do not force a PSU into a slot as this action may damage the PSU or the S4048–ON chassis. NOTE: If a PSU fails, you must replace the entire unit. There are no field serviceable components in the PSU. To request a hardware replacement, refer to Technical Support.
3. Insert the PSU into the switch PSU slot. Insert the PSU exposed PCB edge connector first. The PSU slot is keyed so that the PSU inserts fully in one orientation only. Figure 15.
