Power Supply Blanks, Removing a Power Supply Module

NOTE: A 2700 W power supply module requires 110 V to 240 V input from an AC power source. If a power supply module is plugged into a 110 V electrical outlet, the power supply operates at 1350 W, if you select the Allow 110 VAC Operation check box in the CMC Power Configuration screen.

NOTE: The power supply modules have internal fans that provide thermal cooling to these modules. A power supply module must be replaced if an internal fan failure occurs.

The CMC module controls power management for the system. You can program the CMC to configure the power budget, redundancy, and dynamic power of the entire enclosure (chassis, servers, I/O modules, iKVM, CMC, and power supplies). The power management service optimizes power consumption and re-allocates power to different modules based on real-time demand. For more information, see the CMC User's Guide at support.dell.com/manuals.

NOTE: The wattage of a power supply module is listed on its regulatory label.

NOTE: PDU inlet cords for this system may be too thick to fit in the wire guides installed in the rack vertical rails. If this is the case, remove the wire guides by removing the attachment screw securing each guide. Route the PDU inlet cords along the vertical rails, securing them with tie wraps or strips.

Power Supply Blanks

If the M1000e enclosure is operated with only three power supplies, power supply blanks must be installed in the three unoccupied power supply bays (4 through 6) to maintain proper cooling airflow in the enclosure.
