Intel MFSYS25 - AXXPSU 1000W Power Supply Module, User Manual, Page: 18 / 164

6 Intel® Modular Server System MFSYS25 User Guide
One power supply will support one compute module plus all other modules in the system.
Two power supplies will support 2 to 3 compute modules (in any slot) plus all other
modules in the system.
Three power supplies will support four to six compute modules (in any slot) plus all other
modules in the system.
Any additional power supplies above the minimum required (based on configuration) will
provide redundancy.
I/O Module Slots
The middle-rear of the chassis can accommodate up to four expansion modules.
Ethernet Switch Module
One or two hot-swap Intel® Gigabit Ethernet Switch modules can be installed. Each
switch has ten uplink ports and twelve internal server bay ports, two ports routed to each
compute module. One switch module is the minimum configuration for external
networking; a second switch module allows for network module redundancy.
Storage Controller
One or two hot-swap Intel® Storage Controllers can be used with 14 hot-swap drives in
the front to support hard disk drives in the chassis. One storage controller is the minimum
configuration; a second storage controller allows for storage controller redundancy. When
two storage controllers are installed and one fails, drive access is maintained through the
operational storage controller.
Management Module
The Intel
®
Management Module is installed in the middle-rear of the chassis, between the
four I/O slots. This module provides an Internet browser interface that allows the
configuration and management of the entire Intel
®
Management Module. This module is
not redundant but the system will continue to operate normally if this module fails.
However, any changes to the system configuration will not be recognized until the failed
management module is replaced.
Main Cooling Modules
Two hot-swap main cooling modules are installed on the left rear of the chassis. Each
module contains a redundant fan. Main cooling modules maintain separate zones in the
chassis. Both modules are required to properly cool all compute modules.
