Obtaining The Imm Host Name - Lenovo System x3250 M4 Installation And Service Manual

• 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 IMM host name

Use this information to obtain the IMM host name.
If you are logging on to the IMM for the first time after installation, the IMM defaults to DHCP. If a DHCP
server is not available, the IMM uses a static IP address of 192.168.70.125. The default IPv4 host name
is "IMM-" (plus the last 12 characters on the IMM MAC address). The default host name also comes on
the IMM network access tag that comes attached to the power supply on the rear of the server. The IMM
network access tag provides the default host name of the IMM and does not require you to start the server.
The IPv6 link-local address (LLA) is derived from the IMM default host name. The IMM LLA is on the IMM
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 IMM 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.
Step 7. Convert the binary back to hexadecimal (for example, 5E F3FCFFFE5EAAD0).
