Using The Remote Presence And Blue-Screen Capture Features - Lenovo System x3250 M5 Installation And Service Manual

• 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 II (IMM2).
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 memory and mapping it to the server as a virtual drive
The blue-screen capture feature captures the video display contents before the IMM2 restarts the
server when the IMM2 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 host name
Use this information to obtain the IMM2 host name.
If you are logging on to the IMM2 for the first time after installation, the IMM2 defaults to DHCP. If a DHCP
server is not available, the IMM2 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 MAC address). The default host name also comes on the
IMM2 network access tag that comes attached to the power supply on the rear of the server. The IMM2
network access tag provides the default host name of the IMM2 and does not require you to start the server.
The IPv6 link-local address (LLA) is derived from the IMM2 default host name. The IMM2 LLA is on the IMM2
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 MAC address (for example, 5CF3FC5EAAD0).
Step 2. Separate the number into pairs of hexadecimal characters (for example, 5C:F3:FC:5E:AA:D0).
Step 3. Separate the first six and last six hexadecimal characters.
Step 4. Add "FF" and "FE" in the middle of the 12 characters (for example, 5C F3 FC FF FE 5E AA D0).
Step 5. Convert the first pair of hexadecimal characters to binary (for example, 5=0101, C=1100, which
results in 01011100 F3 FC FF FE 5E AA D0).
Step 6. Flip the 7th binary character from left (0 to 1 or 1 to 0), which results in 01011110 F3 FF FE 5E AA D0.
