HP Switch 2000 Redundant Power Supply
At A Glance
The HP J3136A AdvanceStack Switch 2000 Redundant Power Supply
provides redundant DC power to the HP J3100A AdvanceStack Switch 2000.
The Redundant Power Supply (RPS) shares the power load with the Switch
2000’s main power supply. If the Switch 2000’s power supply components
were to fail, the RPS power supply component will instantly supply power to
the Switch 2000.
Features
Network Connections Provides fully redundant power to the Switch 2000.
Modular, Easy-to-Use Design The RPS is easy to mount on the back of the Switch 2000.
Each Switch 2000 has an RPS LED to report the status of the Redundant Power
Supply.
RPS status information available from HP Stack Manager (Windows 3.1
software shipped with the devices that support the RPS) and HP Interconnect
Manager.
Management SNMP indication on the RPS connection and the RPS fault condition through the
connected devices.
