PCIe slots
The PCIe slots are on the rear of the server and your server supports up to eight PCIe slots on riser 1, 2, and
3 assemblies. Below lists all supported parts in the slots:
• RAID/HBA adapters
• COM cable
• GPU adapters
• PCIe SSDs
• PCIe switch
• 7mm SSDs (slot 6 only)
Power supplies
The hot-swap redundant power supply helps you avoid significant interruption to the operation of the system
when a power supply fails. You can purchase a power supply option from Lenovo and install the power
supply to provide power redundancy without turning off the server.
On each power supply, there are three status LEDs near the power cord connector. For information about the
LEDs, see "Rear view LEDs" on page 41.
USB 3.1 Gen 1 connectors
The USB 3.1 Gen 1 connectors can be used to attach a USB-compatible device, such as a USB keyboard,
USB mouse, or USB storage device.
VGA connector
The VGA connectors on the front and rear of the server can be used to attach a high-performance monitor, a
direct-drive monitor, or other devices that use a VGA connector.
XClarity Controller network connector
The XClarity Controller network connector can be used to attach an Ethernet cable to manage the baseboard
management controller (BMC).
