Cisco Crs 3-Phase Ac Power Distribution Unit - Cisco CRS-1 System Description

Cisco CRS 3-Phase AC Power Distribution Unit

• Fault induced shutdown occurred
• Thermal sensor fault
• Vout out of range
• Boost Vbulk fault
Once all of the faults have been removed and the power module is operating normally, the Internal Fault LED
is turned off.
Cisco CRS 3-Phase AC Power Distribution Unit
This section describes the Cisco CRS Power Distribution Unit (PDU). The PDU converts 3-phase AC input
power to single-phase AC output power that connects directly to the rear of the modular configuration AC
power shelf.
The AC PDU includes either an AC Delta or AC Wye power interface, and has power input and power output
cords entering and exiting the box. The PDU can be installed in a 19-inch rack or other locations, depending
on the PDU type, by using chassis mounting brackets. In this section, single PDU refers to the individual PDU
that converts 3-phase AC input power to single-phase AC output power.
A PDU kit refers to all the components that are required to be installed in a redundant CRS system. A PDU
kit contains 2 single PDUs and any necessary mounting brackets or hardware. When ordering an AC-powered
Cisco CRS system, the appropriate PDU kit Product ID should also be ordered.
Cisco Product ID numbers for PDU kits are as follows:
• CRS-8-PDU-Delta—Redundant 3-phase to single-phase Delta PDU for Cisco CRS 8-slot Line Card
• CRS-8-PDU-Wye—Redundant 3-phase to single-phase Wye PDU for Cisco CRS 8-slot Line Card
The following figure shows the Power Distribution Unit 8D (Cisco product number PDU-321-3-Delta) that
converts 3-phase AC Delta input power to single phase output power.
