This follows Amp Guard product 130651, manual 130820 Rev 02. 192.168.251.1 is its temporary service Wi-Fi route. For an existing LAN installation, use the current DHCP-assigned address instead.

Open this local interface

While connected to the identified monitor's already available service Wi-Fi, enter 192.168.251.1 in the browser address bar and follow the owner's installed access details.

Obtain the current authorized unit PIN from the owner. Rev 02 documents an eight-digit PIN on the front label or Quick Guide for Wi-Fi and Local management login. No universal PIN, username or numeric management scheme/port is established.

Confirm the service network

Rev 02 documents AG_*******, ending in seven serial-number digits, and a ten-minute AP window after power-on. The broader support article shows AMPGUARD_NNNNNN with six digits. Confirm the installed model and actual network with the owner.

Read Status

Open Status to inspect existing measurements. Leave Installation, network updates, load-balancing configuration and System controls unchanged.

If access fails

Ask the administrator to confirm the current PIN and available route. Do not press reset, operate a fuse, disconnect cables or open the cabinet to create a session.
