Automatic Power Transfer Switch

The Automatic Power Transfer Switch allows servers and other equipment with three power supplies in an N+1 redundant configuration (such as the V880/V890) to be connected to two supply power grids without losing availability in the event of either one of the two power grids failing. The switch is supported in the Sun StorEdge 72" and 900/1000 racks.

Features:

• Allows equipment with three power supplies (in a N+1 redundant configuration) to be powered by two utility power grids and survive the failure of one of the grids
• Can be used to provide a resilient power source for devices with a single power supply
• 1U rack mounted
• Can be used with both StorEdge 72" and Sun Rack 900/1000 cabinets
• Ideal for V880 and V890 servers
• Two 16A IEC C20 power inputs for connection to two incoming power grids
• One IEC C19 and eight IEC C13 outputs, maximum total load 16A
• Fast switching time prevents server interruption during switchover
• Includes two IEC C19 to C20 input power cords for use with StorEdge rack
• Overload protection (circuit breaker trip guards included)
• Supports out-of-phase inputs
• Front panel status LEDs
• Includes rackmount kit and cable management bracket
• Includes engineer on-site installation (UK mainland, normal working hours)
• RoHS compliant

• Up to two V880/V890 servers may be connected to one Automatic Power Transfer Switch when configured as above.
• The standard StorEdge 72" rack sequencers are used to distribute the power to both the Automatic Power Transfer Switch and directly to two power supplies in the V880/V890(s).
• It is expected that the Transfer Switch will be located in the lower half of the rack. Should the Transfer Switch need to be located in the top of the rack, order 1 off UKT-R1U-ATS-XKIT to accompany it.

• Input cables are provided by option X6829A – not included (two of the four cables delivered by this option are required per ATS).
• The supply power requirement will be 2x IEC309 16A sockets per ATS.
• The Sun Rack 900/1000 Power Distribution System is not required or used for the V880/V890 power connection.
• This configuration may be doubled when two V880/V890 servers are to be installed in one Sun Rack (using 2 Automatic Power Transfer Switchs).
• One Sun Rack Power Distribution System and one Automatic Power Transfer Switch may be installed when only one V880/V890 is present.
• It is expected that the Transfer Switch will be located in the lower half of the rack. Should the Transfer Switch need to be located in the top of the rack, order 1 off UKT-R1U-ATS-XKIT to accompany it.

Order Code:

• Rack mount kit
• Cable management bracket
• Two IEC C19 to C20 input power cables (used when installed in a StorEdge 72" rack)
• Installation documentation
• Onsite engineer installation (UK mainland only, normal working hours)

• Two IEC309/16A plug to IEC309/C19 16Amp input power cables, 4 meters long
• Three IEC320/C13 to IEC320/C14 10Amp power cables, 3 meters long

• V880/V890 systems in a StorEdge 72" Rack will require the cables within the V880/V890 rack mount kit (X8628A).
• V880/V890 systems in a Sun Rack 900/1000 will require 1x X6829A (sufficient for two ATS) and the cables within the V880/V890 rack mount kit (X8638A)
