Suspected Cause and Action To Be Taken
 Check if both the Gateway and the destination
equipment are turned on.
 Check if the wired LAN connection to the
destination equipment meets the networking
environment of your premise.
 Check if the wired LAN facility in the destination
equipment (LAN board or LAN card) is properly
configured.
 Reconnect the LAN cable between the subject
LAN port of the Gateway and the LAN port of
the destination equipment until you hear a click
from each port connection.
 When the user prepares a LAN cable, procure
a LAN cable of category 5e or higher if 1 Gbps
(1000 Mbps) link speed for 1000BASE-T is
desired. Otherwise, slowdown of link speed or
communication failure may result.
 Referring to instruction manual of the
connected PC, set up the wired LAN
connection of the connected PC so that the IP
address of the connected PC is automatically
assigned by DHCP server (the Gateway).
 To cause the above setting to take effect, the
Gateway needs to start up and become ready
prior to startup of the connected PC. To
ensure this, recycle power of the connected PC
while the Gateway is running.
 Check if the connection is appropriate referring
to Chapter 4 (wired connection) or Chapter 5
(wireless connection).
 Set up the OS and the browser so as not to use
proxy.
 Temporarily terminate firewall and/or antivirus
software, if running on the user PC, before
trying to open the "EMS Gateway" setup page.
 Enable JavaScript™ in the browser settings.
 Use compatible browser defined in
Subsection 1.3.2.
 Check if the latest firmware version is applied
and, if not, perform firmware upgrade according
to Chapter 6.
 Initialize the Gateway and set up the Gateway
from scratch according to Section 8.1.
