This ALOM release supports the following platforms:
The Sun Fire V210 server does not have a front panel keyswitch. The Sun Fire V240 and V440 servers do have keyswitches. The Sun Fire V250 server has an operation mode switch on the front panel, which supports the same functionality as the keyswitch but does not require a key to operate. The Netra 240 server and Netra 440 server have a rotary switch. Before you update the ALOM firmware using either the flashupdate or scadm download command, make sure that the rotary switch, keyswitch, or operation mode switch is set to the Normal position or unlocked position (Netra 240, Netra 440).
For more information, refer to the Administration Guide for your server.
On the Sun Fire V210 and V240 servers, the ALOM hardware is an integral component of the server's motherboard.
On the Sun Fire V440 server, the ALOM hardware consists of a discrete system controller card. The card plugs into a dedicated slot on the server's motherboard. The serial management (SERIAL MGT) and network management (NET MGT) ports are located on the back of the card, and can be accessed from the back of the server.
On the Sun Fire V250 server, the ALOM hardware consists of the system controller card located above the PCI slots. The serial management (SERIAL MGT) and network management (NET MGT) ports are located on the rear of the ALOM card and can be accessed from the rear of the server.
The system configuration card (SCC) stores important information for the host server, including network and OpenBoot™ PROM information, and ALOM user and configuration data. If your host server fails and needs to be replaced, you can migrate the SCC from the server to a new server. The new server starts up using the original server's configuration data. This minimizes downtime and removes the need to completely configure the new server.
ALOM interacts with the SCC as follows:
For more information about the SCC, refer to the Administration Guide for your server.
