module IP reset button: Do not press this button unless you intend
to erase your configured IP addresses for the management module and lose
connection with the remote management station, the switch modules, and the blade
servers. If you press this button, you will have to reconfigure the management
module settings (see the information beginning with “Setting up the remote
connection” on page 25 for instructions).
Press this recessed button to reset the IP configuration of the management module
network interfaces (Ethernet 1, Ethernet 2, gateway address, and so on) to the
factory defaults and then restart the management module.
Use a straightened paper clip to press the button.
Serial connector: Use this connection for configuring and managing the
BladeCenter components over a serial line through the command-line interface
(CLI) user-interface. This port provides access and redirection to the
serial-over-LAN (SOL) interface of any processor blade server. For example, you
can connect a laptop device to the serial connector and use a terminal-emulator
program to configure the assorted IP addresses, user accounts, and other
management settings through the CLI user-interface.
