Power Supplies
The Cisco MDS 9148S switch supports only AC power supplies. Each power supply provides sufficient
power to maintain switch operation in the event of a single power supply failure. Power supplies are hot
swappable and can be individually replaced without disruption to the system.
The power supply has two LEDs, INPUT OK and OUTPUT OK. Power supply status is also indicated
on a front panel LED.
