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 in 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, and USB flash drive on a remote client, and mapping ISO image files as
virtual drives that are available for use by the server
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
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, which is attached to the power supply on the rear of the server. You can get the
host name without starting the server.
The IPv6 link-local address (LLA) is derived from the IMM2 default host name. To derive the link-local
address, do the following:
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 seventh binary character from left (0 to 1 or 1 to 0), which results in 01011110 F3 FF FE
5E AA D0.
Step 7. Convert the binary back to hexadecimal (for example, 5E F3FCFFFE5EAAD0).
Obtaining the IP address for the IMM2
To access the Web interface to use the remote presence feature, you need the IP address or host name of
the IMM2. You can obtain the IMM2 IP address through the Setup Utility and you can obtain the IMM2 host
name from the IMM2 network access tag. The server comes with a default IP address (192.168.70.125) for
the IMM2.
To obtain the IP address, do the following:
