Power supplies

Power to the blade server is derived from the power supplies that are installed in the chassis. There are no
server options regarding power supplies.

System Management

The server contains an integrated service processor, XClarity Controller (XCC), which provides advanced
service-processor control, monitoring, and alerting functions. The XCC is based on the Pilot4 XE401
baseboard management controller (BMC) using a dual-core ARM Cortex A9 service processor.

Local management

As shown in Figure 2, the SN850 front panel includes a USB port, status indicators, a button to enable
management via the USB port and a console breakout cable port. The breakout cable (supplied with the
chassis) provides serial, video and a USB port for connecting a local console. The USB ports on the
breakout cable support keyboard and mouse; storage devices are not supported.
System status with XClarity Mobile
The Lenovo XClarity Mobile (LXCM) app now includes a tethering function where you can connect your
Android or iOS device to the server via USB to see the status of the server.
The steps to connect the mobile device are as follows:
1. Enable USB Management on the server, by pressing and holding for 3 seconds the dedicated USB
management button on the front of the server.
2. Connect the mobile device via a USB cable to the server's USB port with the management symbol
3. In iOS or Android settings, enable Personal Hotspot or USB Tethering
