Chapter 4: Power Supplies and Fans
Chapter 4
Power and Cooling
The MicroBlade enclosure integrates a power supply and a cooling fan into a single module.
The fan can operate independently from the power supply, so that if the power supply fails,
the fan continues to provide cooling for the system. The Chassis Management Module (CMM)
monitors the status of the power supplies and the power information for the enclosure.

Power Cord
A plastic locking clip partially covering the socket was designed to prevent the power supply
module from being removed with the power cord still connected.
Only the recommended power cord or an equivalent 14 gauge cord should be used. Typical
C13/C14 cords are only 16 Gauge wiring and pose a fire hazard if substituted.
