Preboot Execution Environment (PXE)

The Intel PXE technology enables you to boot your computers, load an operating system, or deploy executable images from a remote server by using a network interface. The operation can be done independently of local data storage devices (such as hard disk drives) or installed operating systems.

Redundant Array of Independent Disks (RAID)

Your server supports onboard SATA software RAID and advanced SATA/SAS hardware RAID configurations if you have a required RAID card installed. For detailed information, see “Configuring RAID” on page 71.

Status light-emitting diodes (LEDs) and diagnostic LEDs

For more information about the LEDs for your server, refer to the related topics in “Locations” on page 13.

ThinkServer EasyStartup program and ThinkServer EasyUpdate Firmware Updater program For more information about the software programs, see “Software” on page 12.

Wake on LAN

When the Wake on LAN feature is enabled on a computer that is connected to a local area network (LAN), a network administrator can remotely turn on or wake up the computer from a management console using remote network management software. Besides, many other functions, such as data transfer and software updates, can be performed remotely without remote attendance and can be done after normal working hours and on weekends to save time and increase productivity.

Advanced system management features

The BMC firmware supports the following advanced system management features:

Note: The advanced system management features are only available when the BMC detects the presence of an integrated keyboard, video, and mouse (iKVM) key. The iKVM key is a remote management module. You can purchase an iKVM key from Lenovo and install it on the iKVM key connector on the system board of your server to enable the iKVM function and activate the advanced system management features.

iKVM redirection

The BMC firmware supports iKVM redirection over LAN. This feature is available remotely from the embedded Web server. The remote management module can digitize and compress the collected keyboard, video, and mouse signals from the host system and then send them to the remote console. Meanwhile, it is easily accessible by remote KVM and controllable through LAN or Internet. For detailed information, refer to the Remote Management Module User Guide on the documentation DVD that comes with your server.

Media redirection

The embedded Web server provides a Java JNLP to enable the remote media redirection. This is used in conjunction with the remote KVM feature or as a standalone applet.

The media redirection feature is intended to enable system administrators or users to mount a remote optical drive, floppy drive, or USB flash disk as a USB device to the server. Once mounted, the remote device functions as a local device to the server, enabling system administrators or users to boot the server and install software (including operating systems), copy files, update the BIOS from this device.

Web Services for Management (WS-MAN)

The BMC firmware supports the WS-MAN specification.

Local Directory Authentication Protocol (LDAP)

The BMC firmware supports the LDAP for user authentication.

Note: The IPMI users, passwords, and sessions are not supported over LDAP.
