Power supplies and fans

The IBM Ethernet Switch B24X comes with one 300 W AC power supply and supports a second power supply for 1+1 redundancy. The power supplies are hot-swappable, auto-sensing, auto-switching, and load sharing, with a universal input (90 VAC to 264 VAC). The power supply has an IEC-C14 inlet that connects to a C13 power connector. Power cords are not included with the switch and must be provided separately.

The IBM Ethernet Switch B24X also comes with a single fan tray consisting of three variable-speed fans. If one fan within the fan tray fails it does not affect the operation of the other fans in the unit. The fan tray is hot-swappable, increasing device availability and serviceability.
