Power Supplies

The VOYAGER 3000 uses two high performance power supply units per backplane. A single power supply is rated at 180 Watts. Each power supply is rated at greater than 500,000 hours MTBF with a second power supply providing full redundancy capabilities. The Power supply units are housed in bays 8 through 9 within the cabinet and are mounted in removable shuttles for ease of maintenance. Figure 1-8 shows a Power Supply Unit housed in the canister.
