Maintenance Button
The maintenance button is a multifunction momentary switch on the front panel. It
has the following functions:
 Reset a Router (see page 1-5)
 Reset and Select Boot Image (see page 1-5)
 Reset IP Address (see section page 1-5)
 Enable DHCP (see section page 1-5)
 Restore Factory Defaults (see page 1-5)
Reset a Router
To reset the router, use a pointed, nonmetallic tool to momentarily press and
release (less than two seconds) the maintenance button. The router responds as
follows:
1. All the chassis LEDs light up.
2. After about two seconds, the POST begins, turning off the heartbeat and
system fault LEDs.
3. When the POST is complete, the power LED is on and the heartbeat LED
flashes once per second.
