R0106-HP MSR Router Series Fundamentals Command Reference(V7)

242
Usage guidelines
Password recovery capability controls console user access to the device configuration and SDRAM from
Boot ROM menus.
If password recovery capability is enabled, a console user can access the device configuration without
authentication to configure new passwords.
If password recovery capability is disabled, console users must restore the factory-default configuration
before they can configure new passwords. Restoring the factory-default configuration deletes the
next-startup configuration files.
To enhance system security, disable password recovery capability.
Availability of Boot ROM menu options varies by the password recovery capability setting. For more
information, see the release notes.

Parameters
slot slot-number: Specifies a subcard by its subslot number. (On an MSR2000 or MSR3000.)
slot slot-number: Specifies a card by its slot number. (On an MSR4000.)
subslot subslot-number: Specifies a subcard by its subslot number. If you do not specify this option, the
command stops supplying power to all subcards on the card.
Usage guidelines
When power is insufficient, you can power off interface cards that are idle or connected to unimportant
network nodes to ensure power supply to critical interface cards.
Examples
# On an MSR4000, power off the card in slot 9.
