backup-battery reset
Note
The
backup-battery reset
command only works on routers using the Cisco CG-OS operating system.
To reset the BBU power (power off the BBU, then power it back on), use the
backup-battery reset
command in user EXEC mode:

charge.
To disable the BBU automatic discharge feature, use the
backup-battery inhibit discharge
command
in user EXEC mode. Use this command to disable the BBU automatic discharge when you disconnect
the router from AC power, and want to prevent the BBU from automatically discharging; for example
when you are shipping the router, or transporting it between locations. When the BBU discharge is
disabled, the BBU LED displays the amber slow blinking state. Use the
backup-battery un-inhibit
discharge
command to enable the BBU automatic discharge after disabling it.
