Switch configurations You can order the S3048–ON switch in several different configurations.
3 Site preparations The S3048–ON 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 S3048–ON specifications, see Specifications. NOTE: Install the S3048–ON switch into a rack or cabinet before installing any optional components.
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.
• 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. Always wear an ESD-preventive wrist or heel ground strap when handling the S3048–ON and its accessories. After you remove the original packaging, place the S3048–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 rear aisle.
5 Install the S3048–ON To install the S3048–ON switch, complete the installation procedures in the order presented in this chapter. Always handle the S3048–ON and its components with care. Avoid dropping the switch or its field replaceable units (FRUs). This chapter describes the installation procedures as follows: 1 Unpack 2 Rack or cabinet hardware installation 3 Switch installation 4 Optics installation 5 Power up the switch NOTE: ESD damage can occur if components are mishandled.
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. Rack or cabinet hardware installation You may either place the switch on a rack shelf or mount the switch directly into a 19" wide, EIA-310- E-compliant rack—four-post, twopost, or threaded methods.
Figure 5. 1U tool-less configuration 2 Align and seat the front flange pegs in the holes on the front side of the vertical post, item 2. 3 Repeat this procedure for the second rail. 4 To remove each rail, pull on the latch release button on each flange ear and unseat each rail, item 3. Two-post flush-mount installation 1 For this configuration, remove the castings from the front side of each ReadyRails assembly, item 1.
Figure 6. Two-post flush-mount configuration 2 Attach one rail to the front post flange with two user-supplied screws, item 2. 3 Slide the plunger bracket forward against the vertical post and secure the plunger bracket to the post flange with two user-supplied screws. item 3. 4 Repeat this procedure for the second rail.
Figure 7. Two-post center-mount configuration 2 Slide the back bracket towards the post. Secure it to the post flange with two user-supplied screws, to item 2. 3 Repeat this procedure for the second rail. Four-post threaded installation 1 For this configuration, remove the flange ear castings from each end of the ReadyRails assemblies. To remove the two screws from each flange ear and remove each casting, use a Torx driver, item 1. Retain the castings for future rack requirements.
Figure 8. 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. Switch installation You can mount the switch in the 1U front-rack or 1U flush or center two-post configurations. The following is an example of a front-rack configuration: For the 1U flush or center two-post configurations, slide the switch into the rails in the same manner as the four-post configurations.
Figure 9. 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 three 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. Figure 10. Front rack installation NOTE: Do not the use the mounted ReadyRails as a shelf or a workplace.
Ground cable Dell EMC recommends you ground your switch. To attach the ground cable to the chassis, use a single M4x0.7 screw. The cable itself is not included with the S3048–ON switch. 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.
• 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 S3048–ON. For more information, see Specifications. • There is sufficient airflow around the unit. • The input circuits are correctly sized for the loads and that you use sufficient overcurrent protection devices. • All protective covers are in place.
6 Power supplies The S3048–ON ships with one AC power supply. Dell EMC recommends purchasing a second power supply. The S3048–ON supports AC power supplies with two air-flow directions—from the I/O side to the PSU side and 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.
WARNING: Prevent exposure and contact with hazardous voltages. Do not attempt to operate this switch with the safety cover removed. 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.
NOTE: The S3048-ON powers up when you connect the cables between the power supply and the power source. 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 S3048– ON chassis. NOTE: If a PSU fails, you must replace the entire unit. There are no field serviceable components in the PSU.
7 Fans The S3048–ON comes from the factory with one PSU and three fan modules installed in the chassis. The fan modules and the power supplies, which have integrated fans, are hot-swappable. NOTE: To run the switch, all slots must have operating fan units. If you do not install a module in each slot either as part of the PSU or as an independent fan module, the switch shuts down in one minute. In addition to the power supply modules, you can order and install fan modules separately.
1 Fan modules Fan module installation The fan modules in the S3048–ON are field replaceable. Module slot 1 is on the left side of the chassis, module slot 2 is in the middle of the chassis, and module slot 3 is on the right side of the chassis. CAUTION: DO NOT mix airflow directions. All fans must use the same airflow direction—reverse or normal. If you mix the airflow direction, the switch detects the discrepancy and issues an alarm. You must correct the mixed airflow direction.
8 Management ports Besides the 10/100/1000Base-T RJ-45 ports, the S3048–ON switch provides several ports for management and storage. Topics: • RS-232 console port access • Before you install an OS • ONIE service discovery RS-232 console port access The RS-232 console port is on the I/O-side of the S3048-ON chassis, as shown. Figure 14.
USB-B console port access The USB-B console port is on the I/O side of the S3048-ON. The terminal settings are the same for the serial console port and the RS-232/RJ-45 console port: • 115200 baud rate • No parity • 8 data bits • 1 stop bit • No flow control When you connect the USB-B port, it becomes the primary connection and, while connected, all messages are sent to the USB-B port. NOTE: Before starting this procedure, be sure you have a terminal emulation program already installed on your PC.
