Maintenance button
The Maintenance button is a multifunction momentary switch on the front panel. It provides the following
functions:
• Reset
• Select boot image
• Reset IP address
• Enable DHCP
• Factory defaults
Resetting the mpx100/100b
To reset the mpx100/100b, use a pointed nonmetallic tool to briefly press and release (less than two
seconds) the Maintenance button. The mpx100/100b responds as follows:
1. All the chassis LEDs are illuminated.
2. After approximately two seconds, the power-on self-test (POST) begins, extinguishing the Heartbeat
and System Fault LEDs.
3. When the POST is complete, the Power LED illuminates and the Heartbeat LED flashes once per
second.
Resetting the IP address
To reset the mpx100/100b and restore the maintenance port IP address to the default of 10.0.0.1, briefly
press the Maintenance button with a pointed non-metallic tool, releasing the button after six seconds (six
flashes of the Heartbeat LED). The mpx100/100b boots and sets the maintenance port to IP address
10.0.0.1. The boot time is less than one minute.
NOTE:
Setting the IP address by this method is not persistent; to make the change persistent, use the command line
interface (CLI) or GUI.
Enabling DHCP
Reset the mpx100/100b and configure the maintenance port to use DHCP to access its IP address.
However, enabling DHCP by this method is not persistent. To make the change persistent, use the
CLI or GUI.
Use a pointed nonmetallic tool to briefly press the Maintenance button. Release the button after seven
seconds (observe seven flashes of the Heartbeat LED). The mpx100/100b boots and configures the
maintenance port for DHCP. The boot time is less than one minute.
