System Enclosure Features
The M1000e system enclosure (chassis) includes the following features:
Scalability Features
• Support for up to 16 half-height or 8 full-height blades (server modules).
• Support for three layers of I/O fabric, selectable between combinations
of Ethernet, Infiniband, and Fibre Channel modules.
Up to six I/O modules may be installed in the enclosure, chosen from Fibre
Channel switches, Fibre Channel passthroughs, Infiniband switches,
Ethernet switches, and Ethernet passthrough modules.
Reliability Features
• Nine redundant, hot-pluggable system fan modules.
• Three 2360-watt, hot-pluggable power supplies and three power supply
blanks, or six 2360-watt, hot-pluggable power supplies. (Three power
supplies provide power to the system; adding three additional power
supplies provides 3+3 redundancy.)

Power supplies can only connect to a power distribution unit (PDU).
They cannot connect directly to an electrical outlet.
NOTICE:
The system enclosure requires a 200-240V power source.
