Repeat this procedure for the second rail. Four-post threaded installation NOTE: For more installation instructions, see the installation labels attached to the rail assembly. CAUTION: To be NEBS Earthquake Z4-compliant, you must remove the tool-less latch castings described in Step 1. 1.
Figure 12. Four-post threaded round-hole installation 2. For each rail, attach the front and back flanges to the post flanges with two user-supplied screws at each end. Switch installation You can mount the switch in the 1U front-rack or 1U two-post, flush or center configuration. The following is an example of a front-rack configuration: For the 1U two-post configurations, slide the switch into the rails in the same manner as the four-post configurations.
Figure 13. Attach switch rail 2. After installing both switch rails, line them up on the previously mounted ReadyRails and slide the switch in until it is flush with front of rack. To keep the switch from inadvertently sliding out of the rack and falling, about 3 inches before you fully insert your switch, the rail locking feature engages. Figure 14.
NOTE: Do not the use the mounted ReadyRails as a shelf or a workplace. 3. Tighten the two thumb screws and rack screws. To remove the switch from the rack or cabinet, press in the two side-release bars on the switch at the same time and slide the switch forward. Ground cable NOTE: For AC-powered switches, although the third conductor of the AC power cord provides a ground path, Dell EMC recommends grounding your switch with a dedicated ground wire.
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 S5148F-ON switch after it is mounted in a rack or cabinet.
4. Remove the switch from the rack. At the same time, press in the two side-release bars on the switch and slide the switch forward. If you are using the fan trays or 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.
6 Power supplies The S5148F-ON switch ships with two AC or DC power supplies. The two power supplies have two air-flow directions—from the I/O to the PSU and from the PSU to the I/O. Two PSUs are required for full redundancy, but the switch can operate with a single PSU. The PSUs are field replaceable. When running with full redundancy—two power supplies installed and running—you can remove and replace one PSU without disrupting traffic.
CAUTION: Remove the power cable from the PSU before removing the PSU. Also, do not connect the power cable before you insert the PSU in the switch. NOTE: To comply with the GR-1089 Lightning Criteria for Equipment Interfacing with AC or DC Power Ports, use an external surge protection device (SPD) at the AC or DC input of the router. PSU LEDs ● ● ● ● Solid green—Input is OK. Flashing yellow—There is a fault with the PSU. Flashing green blink at 1Hz—Switch is in a standby/CR state. Off—PSU is off.
AC or DC 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 S5148F-ON switch. 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, see Dell EMC support.
WARNING: Do not cross the wires. In the wiring block, RTN aligns with RTN and –48V aligns with –48V. 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. NOTE: To remove the power connector from a DC PSU, use the orange tab on the side of the connector.
7 Fans The S5148F-ON switch comes from the factory with two PSUs and four fan modules installed in the switch. The fan modules and the power supplies, which have integrated fans, are hot-swappable. In addition to the power supply modules, you can order and install fan modules separately. The S5148F-ON switch supports two airflow direction options. Do not mix airflow types in a switch; you can use only a single airflow direction in a switch.
Fan module installation The fan modules in the S5148F-ON switch are field replaceable. Module slot 1 is on the left side of the switch; module slot 4 is on the right side of the switch. CAUTION: DO NOT mix airflow directions. All fans must use the same airflow direction—reverse or normal. If you mix the airflow direction, to avoid damage to the switch, you must correct the mixed airflow . 1. Take the fan module out of the shipping box. 2. Slide the module into the bay. Figure 19.
2. Unlatch and remove the first module that needs the filter replaced. 3. Slide the existing filter upwards to remove it from the module. 4. Replace the filter with a new filter of the same size. 5. Reinsert the fan module. 6. Repeat for the remaining modules that need the filter replaced.
8 Management ports Besides the 10/100/1000Base-T RJ-45 ports, the S5148F-ON switch provides several ports for management and storage. NOTE: The output examples in this section are for reference only. Your output may vary.
