Web Console Configuration

These settings are used to restrict access to the module by IP address. Only IP addresses on the list will be
allowed access to the device. You may add a specific address or range of addresses by using a combination of
IP address and netmask, as follows:
To allow access to a specific IP address
Enter the IP address in the corresponding field; enter 255.255.255.255 for the netmask.
To allow access to hosts on a specific subnet
For both the IP address and netmask, use 0 for the last digit (e.g., “192.168.1.0” and “255.255.255.0”).
To allow access to all IP addresses
Make sure that Enable the accessible IP list is not checked.
Additional configuration examples are shown in the following table:

Auto Warning Settings
Auto Warning is triggered by different events. When a checked trigger condition occurs, the MGate can send
e-mail alters, SNMP Trap messages, or open/close the circuit of the relay output and trigger the Fault LED to
start blinking. To enable an e-mail alert, configure the e-mail address on the E-mail Alert page. Likewise, to
enable SNMP Trap alerts, configure SNMP trap server on the SNMP Trap page.
