How to reset my switch to factory default

[kwchiang]

Hi all! I bought a Summit X460-24 switch from another seller . when I went to the terminal in puTTy and the console screen is blank.  How to reset the switch to factory setting so I can use “admin” to log in console?

Sniff has to be done with tcpdump or wireshark.

It is Ethernet trafic…

It has to be done on management port, not console port without serial adapter.

I refer to my colleague who bought it, he told me the switch was in Pacman mode which we don’t know how to fix it.

Did you tried to sniff the mgmt port to check if you see any ip traffic?

I try to sniff with COM1 but no data.

Or the serial connection is not correctly configured/operational (serial connection to be double checked) or the switch is not working correctly (RMA to be requested).

Did you tried to sniff the mgmt port to check if you see any ip traffic?

Did you tried to sniff any other port to check if you see any lldp/cdp/edp traffic?

Not seeing any boot process. Always blank screen, no matter I press spacebar or return key
