Installing A DC Power Supply
NOTE: For equipment using –(48–60) V DC power supplies, a qualified electrician must perform all connections to DC
power and to safety grounds. Do not attempt connecting to DC power or installing grounds yourself. All electrical wiring
must comply with applicable local or national codes and practices. Damage due to servicing that is not authorized by Dell
is not covered by your warranty. Read and follow all safety instructions that came with the product.
1. Verify that both the power supplies are the same type and have the same maximum output power.
NOTE: The maximum output power (shown in Watts) is listed on the power supply label.
2. If applicable, remove the power supply blank.
3. Slide the new power supply into the chassis until the power supply is fully seated and the release latch snaps into place.
NOTE: If you unlatched the cable management arm, re-latch it. For information about the cable management arm,
see the system’s rack documentation.
4. Connect the safety ground wire. See Assembling And Connecting The Safety Ground Wire.
5. Install the DC power connector in the power supply. See Assembling The DC Input Power Wires And DC Power Connector.
6. Connect the power wires to a DC power source.
NOTE: When installing, hot-swapping, or hot-adding a new power supply, allow several seconds for the system to
recognize the power supply and determine its status. The power-supply status indicator turns green to signify that
the power supply is functioning properly.
Fan Modules
The M1000e enclosure contains nine hot-swappable fan modules. All nine fan modules must be installed at all times to ensure proper
cooling.
To provide additional cooling for the blades in the enclosure, you can set the fan module configuration to the Enhanced Cooling Mode
(ECM) in the CMC web interface. The ECM feature is available only when all nine fan slots are populated with third generation M1000e
fans. Disabled ECM may reduce upper ambient temperature support on certain system configurations. ECM should be enabled for the
following conditions:
• PowerEdge M630 systems populated with processors of 120 W or more
• PowerEdge M630 systems deployed in environments where the temperature exceeds 30°C
• Any server module configuration operating in a fresh-air environment
For more information on the Enhanced Cooling Mode option, see the latest PowerEdge M1000e CMC User’s Guide at dell.com/
esmmanuals.
Removing A Fan Module
NOTE:
Do not operate the system without the cooling fans.
CAUTION: Exercise care while handling the fan module to prevent damage to the connector on the fan module.
CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and
simple repairs as authorized in your product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow
the safety instructions that are shipped with your product.
1. Identify the failed system fan module using the back-panel fan module indicators.
2. Press the fan-module release button.
3. Slide the fan module out of the enclosure.
