Obtaining the IP address for the IMM

Use this information to obtain the IP address for the IMM.

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:

Note: IPv6 address will not immediately show on host address when we change the values and have to exit and re-visit the driver to get the actual value.
  1. Take the last 12 characters on the IMM MAC address (for example, 5CF3FC5EAAD0).
  2. Separate the number into pairs of hexadecimal characters (for example, 5C:F3:FC:5E:AA:D0).
  3. Separate the first six and last six hexadecimal characters.
  4. Add "FF" and "FE" in the middle of the 12 characters (for example, 5C F3 FC FF FE 5E AA D0).
  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).
  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.
  7. Convert the binary back to hexadecimal (for example, 5E F3FCFFFE5EAAD0).
