Once the BBU is connected, the only way to disable is to use the backup-battery disable command. To
enable the BBU again, issue the backup-battery enable command.
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:
CGR1240# backup-battery reset
This command is functional only when AC power is supplying power to the router. If you enter this
command when the router is powered by the BBU, an error message is displayed.
This command resets all BBUs installed in the router.
backup-battery hard-reset
Note The backup-battery hard-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) while you cannot communicate with
the BBU through the UART interface, use the backup-battery hard-reset command in user EXEC
mode:
CGR1240# backup-battery hard-reset
This command resets all BBUs installed in the router.
backup-battery inhibit discharge
Note The backup-battery inhibit discharge command only works on routers using the Cisco CG-OS
operating system.
Note When the BBU discharge is disabled by the backup-battery inhibit discharge command, the BBU does
not charge, even if it is connected to AC power. The BBU discharge must be enabled by the
backup-battery un-inhibit discharge command, and the BBU connected to AC power, for the BBU to
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.
The backup-battery inhibit discharge command has two effects:
