5–2 Model 2100 and 2200 Ultra SCSI Controller Enclosures User Guide
Configuration
The enclosure accommodates two 180 W power supplies in a redundant power
configuration. The bezel label is a distinguishing feature of a 180 W power supply (see
Figure 5–2).
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.
CAUTION:
Proper enclosure operation
requires
power supplies rated for at least
180 W.
Power supplies are numbered from left to right (PS1 and PS2 respectively), as viewed
from the rear of the enclosure, for error code purposes.
