Features Specific to the Cisco UCS C240 M3 NEBS Server
NEBS Compliance
The Cisco UCS C240 M3 NEBS Server has been certified for the following levels of NEBS compliance:
• The DC-power version of the server is certified for NEBS Level 3 compliance.
• The AC-power version of the server is certified for NEBS Level 1 compliance.
Power Supplies
The Cisco UCS C240 M3 NEBS server can use either AC or DC power supplies.
650 W AC Power Supply
The NEBS server can use one or two 650 W AC power supplies (Cisco PID UCSC-PSU-650W).
• The server is certified for NEBS Level 1 compliance when using these AC power supplies.
• These power supplies are hot-swappable with 1+1 redundancy when two power supplies are present.
• See Power Supply Specifications, page 6, for information about these power supplies.
• See the Cisco UCS C240 Server Installation and Service Guide, Chapter 3, for information about
replacing a power supply.
930 W DC Power Supply
The NEBS server can use one or two 930 W, –48 VDC power supplies (Cisco PID
UCSC-PSU-930WDC).
• The server is certified for NEBS Level 3 compliance when using these DC power supplies.
• These power supplies are hot-swappable with 1+1 redundancy when two power supplies are present.
• See Power Supply Specifications, page 6, for information about these power supplies.
• See the Cisco UCS C240 Server Installation and Service Guide, Chapter 3, for information about
replacing a power supply.
Installation Grounding Requirement (DC Power Supplies Only)
The 650 W AC power supplies have internal grounding and so no additional grounding is required when
the supported AC power cords are used.
When using the DC power supply, additional grounding of the server chassis to the earth ground of the
rack is required. Screw holes for use with your grounding lugs and grounding wires are supplied on the
chassis rear panel.
Note The grounding points on the chassis are sized for M5 screws. The grounding points are spaced at 0.625
inches (15.86 mm). You must provide your own screws, grounding lug, and grounding wire. The
grounding lug required is a Panduit LCD10-14AF-L or equivalent. The grounding cable that you provide
must be 14 AWG (2 mm), minimum 60° C wire, or as permitted by the local code.
See Figure 1-1 for the location of the grounding lug screw-holes on the chassis rear panel.
