CAUTION:
The power control button on the device and the power switch on the power supply do not turn off the
electrical current that is supplied to the device. The device also might have more than one power
cord. To remove all electrical current from the device, ensure that all power cords are disconnected
from the power source.
CAUTION:
Make sure that all server power cords are disconnected from their power sources before performing
this procedure.
• Before you remove the I/O tray, disconnect and label all cables connected to adapters in the I/O tray.
Note: System identification information for the Lenovo ThinkSystem SR950 server is stored in the I/O
tray. If you are removing the I/O tray to replace it as part of a maintenance operation, you will need to
transfer system identification information to the new I/O tray, after it is installed in the server.
• If you are managing the server from Lenovo XClarity Administrator, make sure that you unmanage the
server before removing the I/O tray. Then, you can manage the server again after the new I/O tray has
been replaced.
