The Technical Specifications Sheets for all versions of this server, which include supported component partnumbers, are at Cisco UCS Servers Technical Specifications Sheets (scroll down to Technical Specifications).
Depending on your Cisco IMC settings, Cisco IMC can beaccessed through the 1-Gb dedicated management port, the1-Gb/10-Gb Ethernet LAN ports, or a Cisco virtual interface card.
Baseboard management
Rear panel:
• One 1-Gb Ethernet dedicated management port (RJ-45connector)
• Two 1-Gb/10-Gb BASE-T Ethernet LAN ports (RJ-45connectors)
The dual LAN ports can support 1 Gbps and 10 Gbps,depending on the link partner capability.
• One RS-232 serial port (RJ-45 connector)
• One VGA video connector port (DB-15 connector)
• Two USB 3.0 ports
Front panel:
• One front-panel keyboard/video/mouse (KVM) connectorthat is used with the KVM cable, which provides two USB2.0, one VGA, and one DB-9 serial connector.

Six horizontal PCIe expansion slots on two PCIe riser assemblies.
See PCIe Slot Specifications for specifications of the slots.
PCIe I/O
The PCIe bus slots in this server support the InfiniBandarchitecture.
• Optionally, the two rear-loading drive bays support upto two 2.5-inch SAS/SATA drives; or up to two 2.5-inchNVMe SSDs.

OverviewSummary of Server Features
DescriptionFeature
SAS/SATA drives are hot-swappable. NVMe SSDs arehot-pluggable, meaning that they must be shut down in theoperating system before hot-removal.
The server can be ordered with a rear-drive backplane assemblythat provides bays for two rear-loading, 2.5-inch drives:
• Server PID UCSC-C240-M5SN supports up to two rearNVMe PCIe SSDs only.
• All other C240 M5 PIDs support up to two drives:
• When using a hardware-RAID controller card in theserver, SAS/SATA drives or NVMe SSDs are supportedin the rear bays.
• When using software RAID in the server, only NVMeSSDs are supported in the rear bays.
Storage, rear-panel
The server has these internal storage options:
• One USB 3.0 port on the motherboard.
• One micro-SD card socket on PCIe riser 1.
• Mini-storage module socket, optionally with either:
• SD card carrier. Supports up to two SD cards.
• M.2 SSD carrier. Supports either two SATAM.2 SSDsor two NVMe M.2 SSDs.
• Cisco Boot-Optimized M.2 RAID Controller (modulewith two slots for SATAM.2 drives, plus an integratedSATA RAID controller that can control the two SATAM.2 drives in a RAID 1 array)
Storage, internal
The SFF drives, 8-drive version of the server supports afront-loading DVD drive option.
Other removable media
The server has a dedicated internal socket that supports one ofthe following storage-controller options:
• A PCIe-style Cisco modular RAID controller card(SAS/SATA).
• A PCIe-style interposer card for the server’s embeddedSATA RAID controller.
For a detailed list of storage controller options, see #unique_14.
Storage management
The server has a mounting bracket on the removable air bafflefor one supercap unit that is used with the Cisco modular RAIDcontroller card.
