Features
Performance, ease of use, reliability, and expansion capabilities were key considerations in the design of
your system. These design features make it possible for the user to customize the system hardware to meet
the needs today and provide flexible expansion capabilities for the future.
Chassis feature
• Redundant optional power capabilities
The chassis supports up to three 1300-watt, 1600-watt, or 2700-watt hot-swap CRPS AC power supplies,
which provide redundancy.
Important: Power supplies and redundant power supplies in the chassis must be of the same brand,
power rating, wattage, or efficiency level, with the same latch color.
• Chassis management
The chassis midplane with PSoC (Programmable System on Chip) allows monitor and management of
nodes and power supply units in the chassis. A chassis caretaker node is selected by the PSoC
firmware for chassis management.
For the management interface, see
functions can only be performed by the caretaker node, whereas other functions can be performed by all
nodes.
