Figure 5–2. 180 W power supply bezel label
One power supply supports all enclosure operations. A second power supply provides
power redundancy to eliminate the power supply as a single point of failure.
Power supplies are numbered from left to right (PS1 and PS2 respectively), as viewed
from the rear of the enclosure, for error code purposes.
CAUTION: Proper enclosure operation requires power supplies rated for at least
180 W.
