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 tag that comes attached to the power supply on the rear of the server. 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:

  1. Take the last 12 characters on the IMM2.1 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).
