LED indicators
A LED test is exercised at power-up, cycling each LED off, green and
then red for approximately 0.25 seconds. At the same time the power-
on self test of the device is performed.
The following table outlines the indicator condition and the
corresponding status after the power-on self test has been completed:

MAINTENANCE AND TROUBLESHOOTING
Maintenance
The SL-MOD-GW does not require maintenance, nor does it contain
any user-serviceable parts. If the SL-MOD-GW requires service,
contact us directly for assistance.
Refer to the technical support contacts provided at the end of this
document.
Do not open the SL-MOD-GW enclosure; this will void the product
warranty.
Diagnostics and troubleshooting
ELECTRICAL HAZARD
• This equipment must be installed and serviced only by
qualified personnel.
• Qualified persons performing diagnostics or
troubleshooting that require electrical conductors to be
energized must comply with and follow safe electrical work
practices.
Failure to follow these instructions could result in death
or serious injury!
The status web pages served by the SL-MOD-GW, display diagnostic
data that may be helpful in troubleshooting communication problems.
In addition the About page contains information about your specific
SL-MOD-GW, including the serial number and media access control
(MAC) address. Some of these pages show a Clear Counter button.
Clicking this button clears all cumulative readings shown on this
particular page. If power to the SL-MOD-GW is lost, all values reset
to zero.
Configuring and commissioning
The configuration pages are accessed using the integrated web server:
Gateway IP address
Main menu
Configuration sub-menu
Information area
Please consult the SL-MOD-GW User Manual for further details how
to set-up the SL-MOD-GW.
Ethernet & IP configuration
Before configuring the SL-MOD-GW, obtain a unique static IP address,
subnet mask, and default gateway address from your network
administrator.
Use a web browser or a terminal program like HyperTerminal to
configure the SL-MOD-GW's TCP/IP settings with this information.
The factory default IP address of the SL-MOD-GW is 192.168.1.130.
In order to connect to the SL-MOD-GW via TCP/IP, your PC must be
on same IP subnet as the gateway.
IP setup using a terminal program like HyperTerminal
Please consult the SL-MOD-GW User manual for further details on this
method.
