Cisco Catalyst Blade Switch 3120 for HP Boot
Loader Commands
This appendix describes the boot loader commands on the switch.
During normal boot loader operation, you are not presented with the boot loader command-line prompt.
You gain access to the boot loader command line if the switch is set to manually boot, if an error occurs
during power-on self test (POST) DRAM testing, or if an error occurs while loading the operating
system (a corrupted Cisco IOS image). You can also access the boot loader if you have lost or forgotten
the switch password.
Note The default switch configuration allows an end user with physical access to the switch to recover from
a lost password by interrupting the boot process while the switch is powering up and then entering a new
password. The password recovery disable feature allows the system administrator to protect access to
the switch password by disabling part of this functionality and allowing the user to interrupt the boot
process only by agreeing to set the system back to the default configuration. With password recovery
disabled, the user can still interrupt the boot process and change the password, but the configuration file
(config.text) and the VLAN database file (vlan.dat) are deleted. For more information, see the software
configuration guide for this release.
You can access the boot loader through a switch console connection at 9600 b/s. Remove the switch from
the enclosure, insert the switch in to the enclosure, and press the switch Mode button. You should then
see the boot loader Switch: prompt. The boot loader performs low-level CPU initialization, performs
POST, and loads a default operating system image into memory.
