6 Power supplies The S4048T-ON ships with two power supply units. The system supports AC or DC 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 system can operate with a single PSU. The PSUs are field replaceable. When running with full redundancy—two power supply units installed and running, you can remove and replace one PSU without disrupting traffic.
WARNING: Prevent exposure and contact with hazardous voltages. Do not attempt to operate this system with the safety cover removed. 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 chassis. 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 switch.
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 S4048T–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, see Dell Support. NOTE: If you use a single PSU, install a blank plate in the other PSU slot.
7 Fans The S4048T-ON comes from the factory with two PSUs and four fan modules installed in the chassis. The fan modules and the power supplies, which have integrated fans, are hot-swappable. NOTE: To run the system, the four fan slots must have operating fan units. If you do not install a module in each slot, the system shuts down in one minute. In addition to the power supply modules, you can order and install fan modules separately. The system supports two airflow direction options.
Fan module installation The fan modules in the S4048T-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, to avoid damage to the switch, you must correct the mixed airflow. 1. Take the fan module out of the shipping box. 2.
4. Replace the filter with a new filter of the same size. 5. Repeat for the remaining modules that need the filter replaced.
