• Serial port redirection over telnet or ssh.
• SMI handling
• System event log (SEL) - user readable event log.
The IMM also provides the following remote server management capabilities through the OSA SMBridge
management utility program:
• Command-line interface (IPMI Shell)
The command-line interface provides direct access to server management functions through the IPMI 2.0
protocol. Use the command-line interface to issue commands to control the server power, view system
information, and identify the server. You can also save one or more commands as a text file and run the
file as a script.
• Serial over LAN
Establish a Serial over LAN (SOL) connection to manage servers from a remote location. You can remotely
view and change the UEFI settings, restart the server, identify the server, and perform other management
functions. Any standard Telnet client application can access the SOL connection.

Using the remote presence and blue-screen capture features
The remote presence and blue-screen capture features are integrated functions of the Integrated
Management Module 2.1 (IMM2.1).
The remote presence feature provides the following functions:
• Remotely viewing video with graphics resolutions up to 1600 x 1200 at 75 Hz, regardless of the system
state
• Remotely accessing the server, using the keyboard and mouse from a remote client
• Mapping the CD or DVD drive, diskette drive, and USB flash drive on a remote client, and mapping ISO
and diskette image files as virtual drives that are available for use by the server
• Uploading a diskette image to the IMM2.1 memory and mapping it to the server as a virtual drive
The blue-screen capture feature captures the video display contents before the IMM2.1 restarts the server
when the IMM2.1 detects an operating-system hang condition. A system administrator can use the blue-
screen capture to assist in determining the cause of the hang condition.
Obtaining the IMM2.1 host name
Use this information to obtain the IMM2.1 host name.
If you are logging on to the IMM2.1 for the first time after installation, the IMM2.1 defaults to DHCP. If a
DHCP server is not available, the IMM2.1 uses a static IP address of 192.168.70.125. The default IPv4 host
name is “IMM-” (plus the last 12 characters on the IMM2.1 MAC address). The default host name also comes
on the IMM2.1 network access label that is on the pull out tab. The IMM2.1 network access tag provides the
default host name of the IMM2.1 and does not require you to start the server.
The IPv6 link-local address (LLA) is derived from the IMM2.1 default host name. The IMM2.1 LLA is on the
IMM2.1 network access tag is on the power supply on the rear of the server. To derive the link-local address,
complete the following steps:
Step 1. Take the last 12 characters on the IMM2.1 MAC address (for example, 5CF3FC5EAAD0).
