v Uploading a diskette image to the IMM memory and mapping it to the server as
a virtual drive
The blue-screen capture feature captures the video display contents before the IMM
restarts the server when the IMM 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:
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).
Obtaining the IP address for the IMM
Use this information to obtain the IP address for the IMM.
To access the web interface to use the remote presence feature, you need the IP
address or host name of the IMM. You can obtain the IMM IP address through the
Setup utility and you can obtain the IMM host name from the IMM network access
tag. The server comes with a default IP address for the IMM of 192.168.70.125.
To obtain the IP address, complete the following steps:
1. Turn off the server.
Note: Approximately 5 to 10 seconds after the server is connected to power,
the power-control button becomes active.
2. When the prompt <F1> Setup is displayed, press F1. (This prompt is displayed
on the screen for only a few seconds. You must press F1 quickly.) If you have
set both a power-on password and an administrator password, you must type
the administrator password to access the full Setup utility menu.
3. From the Setup utility main menu, select System Settings.
