ATTO Technology, Inc. ATTO FibreBridge Installation & Operation Manual

Internal Power Distribution

The ATTO FC Rack System provides a redundant power scheme with two "hot swappable" Power Supply Modules. Each Power Supply Module feeds 12V to the backplane. From there, the power is distributed to the bridge modules and the fans.

A failure of one power supply will not affect the functionality of the bridge modules or the cooling system since the second supply is still supplying power to the backplane. In a redundant power supply installation, one supply can be removed and replaced without affecting the rest of the system in any way.

The Product Module is responsible for detecting power supply failures, voltage regulation, and failover. NOTE: Power Modules will load balance when there are two present in the ATTO FC Rack System

Power Module

The Power Module is a hot swappable unit that contains enough power to supply two ATTO Product Modules and four cooling fans. It is designed to slide into the ATTO FC Rack System enclosure, in either of the two bays, on the end of the rack enclosure that is closer to the backplane. This is the end that is farthest away from the cooling vents in the sides of the rack enclosure (see figures 3-1, 3-3 and 3-4).

Figure 3.5 Rack System Power Module

The Power Module supplies power to the ATTO Product Modules. In addition it powers the fans for cooling. The Power Module contains a power supply with the following specifications.

∙Input voltage: 110/230V AC, with an operating input range of 90-132V AC or 175-264V ac, 47- 63Hz, single phase. The AC input range selection is automatic. No manual jumper or switch over is required.

∙Output voltage: +12 Volts @ 5 Amps (60 watts) continuous, 5.8 amps (70 watts) peak.
