Optical drives

The server does not support an internal optical drive option, however, you can connect an external USB

optical drive. See

http://support.lenovo.com/en/documents/pd011281

for information about available

external optical drives from Lenovo. Alternatively, use the remote media feature of the IMMv2 and the

Chassis Management Module.

Note: The USB port on the compute node supplies up to 0.5 A at 5 V. For devices that require more

power, an additional power source is required.

I/O expansion options

The X6 compute node has four I/O expansion connectors for attaching I/O adapters, as shown in the

following figure. Installing I/O adapters allows the server to connect to switch modules in the Flex System

Enterprise Chassis. The following figure shows the location of the four I/O expansion slots.

Note: Slots 3 and 4 support only a subset of the adapters that are supported in slots 1 and 2. Slots 3 and

4 do not support dual-ASIC adapters because of the PCIe lanes that are routed to slots 3 and 4. For

specifics, see the "Network adapters" section.
