The IBM Ethernet Switch B48Y leverages the proven IronWare operating system with an
industry-standard CLI so network administrators can utilize their existing skill sets.

Power supplies and fans

The IBM Ethernet Switch B48Y comes with one 210 W AC power supply and supports a second power
supply (81Y1451) 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 B48Y also comes with a single fan tray consisting of four 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.
