• Redundant networking connection
The Lenovo XClarity Controller provides failover capability to a redundant Ethernet connection with the
applicable application installed. If a problem occurs with the primary Ethernet connection, all Ethernet
traffic that is associated with the primary connection is automatically switched to the optional redundant
Ethernet connection. If the applicable device drivers are installed, this switching occurs without data loss
and without user intervention.
• Redundant cooling and power capabilities
The server supports up to four non-hot-swap fans and the fan 4 is the redundant fan. The redundant
cooling by the fan enables continued operation if one of the fans fails.
Some server models support one fixed power supply and some server models support a maximum of two
hot-swap power supplies.
