APC NetBotz 320 Rack Appliance NBRK0320E Manuel D’Utilisation

To change the PPP dial-out/dial-in settings, use the controls to specify the desired settings. When you are 
finished, click OK and any changes you have made will be saved to the appliance. To end the task 
without making any changes to your appliance click Cancel. Click Refresh to update the contents of the 
task pane with the values that are currently stored on the appliance.

When dial-in support is enabled, the appliance places the external modem in “auto-answer” mode. This 
enables the user to initiate a dial-in connection to to the appliance through the external modem. When 
dialing into the appliance, you must provide a user ID and password for a user account with 
Administrator access to authenticate the PPP connection. Once the PPP connection has been established 
you can access the appliance using IP address 192.168.254.1.

PPP/Modem connections are substantially slower than Ethernet and wireless network connections. Using 
SSL to communicate with an appliance over a PPP/Modem link will slow communications even further, 
and if the appliance is attempting to send too much data over a PPP connection you can encounter a 
bottleneck situation, where events never get delivered or get delivered long after they occur.

Request Immediate Dial-Up/
Cancel Dial-Up Request

If the appliance does not currently have an active PPP 
connection to a network, you can click Request Immediate 
Dial-Out to establish a connection. The PPP connection, 
once initiated, will stay active until you click Cancel Dial-
Up Request or the appliance reboots. 

IP traffic is not routed through the appliance, so you will not be able to use the 
appliance PPP connection to access other devices or systems that are on the same 
Ethernet network as the appliance (assuming the appliance is connected to an 
Ethernet network as well as a modem).
