Checking the communication
status with the STATUS lamp
If the keep alive function is enabled in each
connection setting, you can check whether
communication with any connected equipment is
active only by glancing at the STATUS lamp of the
product.

This is convenient as you can check the
communication status without viewing the top page
of the “Basic configuration page”.
Tip
• When you configure a provider connection or VPN
connection (IPsec, L2TP/IPsec, or PPTP LAN-to-
LAN connection) from “Basic configuration page”,
the keep alive function is set to “enable” on the initial
setup screen.
• To check whether the keep alive function is enabled,
view the setup screen of each connection.
Example of setup screen for the “Terminal broadband
connection over PPPoE” connection
When the STATUS
lamp lights up
In a connection setting where the keep alive
function is enabled, communication with any
connected equipment is inactive.
NOTE
• The keep alive function takes time to detect an
inactive state of communication. Accordingly,
communication with connected equipment may not
be available even when the STATUS lamp does not
light up.
• The STATUS lamp also lights up when you update
the firmware revision using the DOWNLOAD button.
For information about behavior of the product when
you upgrade the firmware using the DOWNLOAD
button, please refer to “Upgrading the firmware using
the DOWNLOAD button” (page 155).
When the problem is resolved
The STATUS lamp goes off.
