Chapter 3 Assigning the Switch IP Address and Default Gateway

Assigning Switch Information

The boot loader provides access to the flash file system before the operating system is loaded. Normally,
the boot loader is used only to load, uncompress, and launch the operating system. After the boot loader
gives the operating system control of the CPU, the boot loader is not active until the next system reset
or power on.

The boot loader also provides trap-door access into the system if the operating system has problems so
serious that it cannot be used. The trap-door mechanism provides enough access to the system so that if
it is necessary, you can format the flash file system, re-install the operating system software image by
using the XMODEM Protocol, recover from a lost or forgotten password, and finally restart the
operating system.

Assigning Switch Information

Use the BladeCenter Management Module WEB page to assign IP information to the switch. For more
information, see the IBM BladeCenter QuickStart Guide.

If the switch reboots, the switch uses the IP address, subnet mask, and gateway configured in the
stored-configuration file.

This section has this configuration information:
