Resetting APC via Ping
APC Propeller 2 and APC Propeller 5 have the capability of being reset to defaults by
pinging the device with a certain packet size when the device is booting. During the
startup of the device, when the drivers of the Ethernet interfaces are loaded, the reset
program is started. The reset program suspends startup process for 3 seconds and
waits for ICMP "
echo request
" packet of length 369 bytes. If the packet received, the
reset daemon sets the device to default configuration.
It is recommended to connect PC to the device via switch, as
depending on PC OS settings, the ARP table might be flushed during
wired link status change (connecting the device that will be reset).
Steps to reset to default settings:
Step 1.
Power off the APC device.
Step 2.
Obtain the device MAC address.
Step 3.
Connect a PC to the same physical subnet as the device.
Step 4.
Execute 'arp -s' command to assign the IP address (IP address
should be from the same subnet as PC) to the device MAC address:
arp -s <IP address to assign> <device MAC address>
Note that syntax of MAC address differs depending on OS:
For Linux users
:
AA:BB:CC:DD:EE:FF
For Windows users
:
AA-BB-CC-DD-EE-FF
Step 5.
Start pinging the APC device:
For Linux users
:
ping <IP address> -s 369
For Windows users
:
ping <IP address> -l 369 -t -w 200
Step 6.
Power up device and wait about 30sec or more (depending on device
hardware).
Step 7.
Stop pinging the APC, and let the device boot as usual. The device
should start up with factory default settings.
