Rear view
The rear view of the server varies by model. Depending on the model, your server might look slightly different from the illustrations in this topic.

Rear components overview
Ethernet connectors
Figure 5. OCP module (two connectors, seen from the rear) | Figure 6. OCP module (four connectors, seen from the rear) |
The OCP module provides two or four extra Ethernet connectors for network connections.
By default, any of the connectors on the OCP module can function as a shared management connector.
The OCP module is an optional part. It is default to be installed on the rear and optional in the front of the server.
If the ThinkSystem V3 Management NIC Adapter Kit is installed on the server, it will not be displayed on the PCIe card list of system management software, such as XCC, LXPM, and so on.
Hot-swap drives and drive bays
The drive bays on the front and rear of your server are designed for hot-swap drives. The number of the installed drives in your server varies by model. When you install drives, follow the order of the drive bay numbers.
The EMI integrity and cooling of the server are protected by having all drive bays occupied. Vacant drive bays must be occupied by drive fillers.
PCIe slots
The PCIe slots are on the rear of the server and your server supports up to three PCIe slots on riser 1 and 2 assemblies.
Power supply units
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 Power supply LEDs.
USB 3.1 Gen 1 (5Gbps) connectors
The USB 3.1 Gen 1 (5Gbps) connectors are direct connect interfaces (DCIs) for debugging, which 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).
