Like the [[Arnid:295951|HP Proliant DL380 G5 server|In pictures: Taking apart Hewlett-Packard's Proliant DL380 G5 server]], the D-Link xStack DSN-2100-10 features hot-swappable power supplies in case of a power failure. A status light on each power supply will change from green to orange if there is a failure and there is also an audible alarm. You can replace one of the power supplies while the other picks up the slack. Since both are constantly connected, there is no downtime if one does fail.
D-Link quotes the xStack DSN-2100-10's power consumption at 360W at full configuration.
