1: Storage System Overview
Figure 1-6 shows the ops panel and identifies its components. For more information
about the LEDs and configuration switches, see “ESI/Ops Panel LEDs and Switches” in
Chapter 5.
Figure 1-6 Ops Panel
PSU/Cooling Module
Two power supply cooling modules (PSUs) are mounted in the rear of the enclosure (see
Figure 1-7). These modules supply redundant cooling and power to the enclosure.
Voltage operating ranges are nominally 115 V or 230 V AC, selected automatically.
Note: If a power supply fails, do not remove it from the enclosure until you have a
replacement power supply. The cooling fans in the power supply will continue to operate
even after the power supply fails. Removing a failed power supply and not replacing it
immediately can result in thermal overload.
