Overview of the HRPSU
This chapter describes the HRPSU (High Power Redundant Power Supply Unit)
power rack and power supply module, and describes preparing for installation.
Introduction to the HRPSU
The HRPSU is a hot-swappable power supply that provides uninterrupted
operation to network devices in the event of a network device power supply
failure. The HRPSU is a standalone unit that can support up to four network
devices equipped with redundant power supply outlets.
The HRPSU is a modular system consisting of a power rack (Order No.
AA0002001) with slots for four power supply modules (Order No. AA0005003).
You can install as many modules as needed, between one and four, in the power
rack. Figure 1-1 shows an HRPSU with all four power supply modules installed.
