Resetting to Factory Defaults
APC 5M-18 V2 has 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 daemon is started. The daemon 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 5M-18 V2 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:
Linux OS: AA:BB:CC:DD:EE:FF
Windows OS: AA
-
BB
-
CC
-
DD
-
EE
-
FF
Step 5.
Start pinging the APC 5M-18 V2 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 5M-18 V2, and let the device boot as usual. The device should
start up with factory default settings.
