Chapter 7 Powering Off the Router
Disable the Router BBU at the CLI
To disable the router BBU, you must have access to the router system software command-line interface
(CLI). Start a console or terminal session with the router to access the system software CLI. You can
connect to the router with a direct connection (using a cable) to the router console port, or over the router
WiFi connection.
For more information about starting a console or terminal session with the router, see the following
sections:
•
Starting a Router Terminal or Console Session
•
Configuring the WiFi Interface
For more information about disabling the router BBU at the CLI, go to the
“Disable the Router BBU at
the CLI” section on page 7-2

Using Connected Grid NMS
Depending on how your Connected Grid Network Management System (CG NMS) software is
configured, you may be able to disable the BBU over the network using CG NMS. Check with the
network administrator.
Disable the Router BBU at the CLI
Note
The router can only be disabled by console or terminal access on routers using the Cisco CG-OS
operating system. The BBU cannot be disabled by console or terminal access on routers using the
Cisco IOS operating system.
To completely power down a router with an installed BBU, use the
backup-battery inhibit discharge
EXEC command to disable the BBU.
Caution
Entering the
backup-battery inhibit discharge
command disables the BBU 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.
This example shows how to disable the BBU with the system software CLI:
CGR1240#
configure terminal
CGR1240#
backup-battery inhibit discharge
More information about this command:
•
This command is active only when the BBU is discharging. If you enter this command when the
router is receiving AC power, the CLI displays an error message.
•
Use the
backup-battery un-inhibit discharge
EXEC command to reset the BBU to default
behavior: automatically begin discharging when the router is not receiving AC power.
Disconnect Router AC Power
To disconnect the router from AC power, follow these steps:
