battery charge-discharge {enable | disable}
The default behavior of the BBU is to automatically begin discharging when the router is not receiving
AC power.
Use the battery charge-discharge disable 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 battery charge-discharge
enable command to enable the BBU automatic discharge after disabling it.
The battery charge-discharge disable command has two effects:
• With AC power on, the BBU does not charge.
• With AC power off, the BBU does not power the router (the BBU does not discharge).
This command is functional only when the BBU is supplying power to the router. If you enter this
command when the router is powered by AC power, an error message is displayed.
Caution Entering the battery charge-discharge disable command disables the BBU discharge immediately. You
are not prompted to confirm the command. If you enter this command when the router is operating on
the network and powered by the BBU, the router will immediately power down and will no longer
operate on the network.
To reset the BBU to the default behavior (automatically begin discharging when the router is not
receiving AC power), use the battery charge-discharge enable command.
The battery charge-discharge enable command has two effects:
• With AC power on, the BBU charges.
• With AC power off, the BBU powers the router (the BBU discharges).
To disable the BBU discharge feature:
Step 1 Connect the router to an AC power source.
Step 2 Enter the battery charge-discharge disable EXEC command:
CGR1240# battery charge-discharge disable
To enable the BBU discharge feature:
Step 1 Connect the router to an AC power source.
Step 2 Enter the battery charge-discharge enable EXEC command:
CGR1240# battery charge-discharge enable
