C) P-520r Rescue and Firmware Recovery via TFTP
Booting P-520r in rescue mode:
1. Turn off power on P-520r.
2. Push reset button (see on Figure 4 – Looking Inside the P-520r) when booting on P-520r.
3. Wait 3 seconds, release button.
P-520r boots on rescue mode therefore will get IP address from DHCP.

$ tftp <P-520r_IP_address>
tftp> bin
tftp> put <fimage_p520r.gsi.1.20.0319_16y> <password>
