Product overview
The PowerEdge C4140 is a 1U, 2-socket, incredibly dense purpose-built rack server that emphasizes performance and reliability in key areas
such as virtualization, power, thermal, and systems management. With up to four double-width accelerators in just 1U of space, the C4140
delivers outstanding performance and maximum density while reducing space, cost and management requirements.
The system is designed to handle the most demanding technical computing workloads in nancial services, life sciences, machine and deep
learning, Oil & Gas exploration, and High Performance Computing (HPC). With Intel's Xeon platform and Nvidia's Volta technologies, C4140
lls a key gap as a leading GPU-accelerated platform in the PowerEdge server portfolio to enable a scalable business architecture in a
heterogeneous data center environment.

NIC indicator codes
The NIC on the back panel has an indicator that provides information about the network activity and link status. The activity LED indicates
whether the NIC is currently connected or not. The link LED indicates the speed of the connected network.
Figure 5. NIC indicators
1link indicator 2 activity indicator
Table 5. NIC indicators
Convention Status Condition
A Link and activity indicators are o The NIC is not connected to the network.
B Link indicator is green The NIC is connected to a valid network at its maximum
port speed (1 Gbps or 10 Gbps).
C Link indicator is amber The NIC is connected to a valid network at less than its
maximum port speed.
D Activity indicator is ashing green Network data is being sent or received.
Power supply unit indicator codes
AC power supply units (PSUs) have an illuminated translucent handle that serves as an indicator. The indicator shows whether power is
present or if a power fault has occurred.
NOTE: The 2400 W and 2000 W PSUs use a C19 or C20 connector.
Product overview 11

Figure 6. AC PSU status indicator

Table 6. AC PSU status indicator codes
Power indicator codes Condition
Green A valid power source is connected to the PSU and the PSU is operational.
Blinking amber Indicates a problem with the PSU.
Not illuminated Power is not connected to the PSU.
Blinking green When the rmware of the PSU is being updated, the PSU handle blinks green.
CAUTION: Do not disconnect the power cord or unplug the PSU when updating rmware. If
rmware update is interrupted, the PSUs do not function.
Blinking green and turns o When hot-plugging a PSU, the PSU handle blinks green ve times at a rate of 4 Hz and turns o. This
indicates a PSU mismatch with respect to eciency, feature set, health status, or supported voltage.
CAUTION: If two PSUs are installed, both the PSUs must have the same type of label; for
example, Extended Power Performance (EPP) label. Mixing PSUs from previous generations of
PowerEdge servers is not supported, even if the PSUs have the same power rating. This results
in a PSU mismatch condition or failure to turn the system on.
CAUTION: When correcting a PSU mismatch, replace only the PSU with the blinking indicator.
Swapping the PSU to make a matched pair can result in an error condition and unexpected
system shutdown. To change from a high output conguration to a low output conguration or
vice versa, you must turn o the system.
CAUTION: The 120 V AC PSU is not recommended for this system and using the same can cause
system throttling.
CAUTION: If two PSUs are used, they must be of the same type and have the same maximum
output power.
Locating Service Tag of your system
Your system is identied by a unique Express Service Code and Service Tag number. The Express Service Code is and Service Tag are
found on the back of the system by pulling out the information tag. Alternatively, the information may be on a sticker on the chassis of the
system. This information is used by Dell EMC to route support calls to the appropriate personnel.

IDSDM or vFlash card
The PowerEdge C4140 system supports Internal Dual SD module (IDSDM) and vFlash card. In the 14th generation of PowerEdge servers,
IDSDM and vFlash card are combined into a single module, and are available in the following options:
• vFlash or
• vFlash and IDSDM
The IDSDM/vFlash card can be connected in a Dell-proprietary PCIe x1 slot using a USB 3.0 interface to host. IDSDM/vFlash module
supports two MicroSD cards for IDSDM and one card for vFlash. The MicroSD card capacity for IDSDM are 16, 32, or 64 GB, while for
vFlash the MicroSD card capacity is 16 GB.
NOTE: There are two dip switches on the IDSDM/vFlash card for write-protection.
NOTE: One IDSDM card slot is dedicated for redundancy.
NOTE: It is recommended to use Dell branded MicroSD cards associated with the IDSDM/vFlash congured
systems.
