Reset and Select Boot Image
You can reset the router using either the primary or secondary boot image:
 Primary Image. To reset the router and select the primary boot image, use
a pointed, nonmetallic tool to press and hold the maintenance button until
the heartbeat LED flashes once, and then release the button. The router
boots from the primary boot image. The boot time is less than one minute.
 Secondary Image. To reset the router and select the secondary boot
image, use a pointed, nonmetallic tool to press and hold the maintenance
button until the heartbeat LED flashes twice, and then release the button.
The heartbeat LED flashes twice. The router boots from the secondary boot
image. The boot time is less than one minute.
Reset IP Address
To reset the router and restore the maintenance port IP address to the default
(10.0.0.1), use a pointed, nonmetallic tool to press and hold the maintenance
button until the heartbeat LED flashes six times, and then release the button. The
router boots and sets the maintenance port to IP address 10.0.0.1. The boot
time is less than one minute.
The IP address set by this method is not persistent (saved upon reboot). To make
the change persistent, use the command line interface (CLI) or Router Manager to
set the IP address. For more information, see the iSR6152 Router Manager
User's Guide or the iSR6152 Router CLI User's Guide.
Enable DHCP
To reset the router and configure the maintenance port to use DHCP to acquire its
IP address, use a pointed, nonmetallic tool to press and hold the maintenance
button until the heartbeat LED flashes seven times, and then release the button.
The router boots and configures the maintenance port for DHCP. The boot time is
less than one minute.
Enabling DHCP by this method is not persistent; to make the change persistent,
use the command line interface (CLI) or Router Manager to enable DHCP. For
details, see the iSR6152 Router Manager User's Guide or the iSR6152 Router
CLI User's Guide.
Restore Factory Defaults
To reset the router and restore it to the factory default configuration, use a
pointed, nonmetallic tool to press the maintenance button and hold it until the
heartbeat LED flashes 20 times, and then release the button. The router boots
and is restored to the factory defaults. The boot time is less than one minute.
The router does the following when restored to the factory defaults:
 Resets all passwords.
 Resets the maintenance port IP address to 10.0.0.1.
