NOTE: Some steps do not apply if you are replacing a different switch or non-Dell EMC switch. NOTE: ESD damage can occur when components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when handling the switch and accessories. After you remove the original packaging, place the switch and components on an anti-static surface.
Power supplies The S5448F-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. CAUTION: PSU and fan airflow directions must match. To avoid damage to the switch, do not mix normal and reverse airflows in a single switch.
4. Plug in the appropriate AC three-prong cable from the switch PSU to the external power source. 5. Repeat steps 1 through 4 if you have a redundant PSU using the second PSU slot on the S5448F-ON switch. 1. When facing the PSU-side of the switch, PSU1 is on the left side of the switch. PSU2 is on the right side of the switch.
= 45-degree C minimum. The altitude of operation is 5000 m. The product must be supplied by a UL-Listed DC power source that is separated from AC mains by double or reinforced insulation when the switch is connected to DC power. For more information, contact your Dell sales representative. NOTE: You need a user-supplied Philips screwdriver to complete this installation.

NOTE: To uninstall the cable from the DC PSU, remove the plastic cover and unscrew the M4 and M5 screws. Pull the DC cable out from the DC PSU socket. Power supplies...
Fans The S5448F-ON switch comes from the factory with two PSUs and six fan modules that are installed in the switch. The fan modules and power supplies, which have integrated fans, are hot-swappable. Besides the power supply modules, you can order and install fan modules separately.
● Flashing yellow—There is a fan fault. ● Off—Fan is off. Fan module installation The fan modules in the S5448F-ON switch are field replaceable. CAUTION: DO NOT mix airflow directions. All fans must use the same airflow direction—reverse or normal. If you must correct the mixed airflow .
Fan module replacement To request a hardware replacement, see https://www.dell.com/support/. CAUTION: Complete the following steps within one minute or the switch temperature could rise above safe thresholds and the switch could shut down: 1. Take the replacement fan module out of the shipping box.
Management ports The S5448F-ON switch provides three ports for management and one USB flash drive mount for file transfers. NOTE: The output examples in this section are for reference only. Your output may vary. Topics: • RJ45 console port access •...
The MicroUSB-B console port is on the I/O side of the switch. NOTE: The S5448F-ON switches use the Silicon Labs CP2102 USB-B chip. To find the correct USB-B universal asynchronous receiver-transmitter (UART) driver, see the Downloads section of the https://www.silabs.com/products/ development-tools/software/usb-to-uart-bridge-vcp-drivers site.
