SE400 SERIES
Installation Guidelines
The following guidelines are provided to optimize the device performance. Review the guide-
lines before installing the device.
Make sure cabling is away from sources of electrical noise. Radios, power lines, and flu-
orescent lighting fixtures can interference with the device performance.
Make sure the cabling is positioned away from equipment that can damage the cables.
Operating environment is within the ranges listed range, see “Specifications” on page 1.
Relative humidity around the switch does not exceed 95 percent (noncondensing).
Altitude at the installation site is not higher than 10,000 feet.
In 10/100 fixed port devices, the cable length from the switch to connected devices can
not exceed 100 meters (328 feet).
Make sure airflow around the switch and respective vents is unrestricted. Without proper
airflow the switch can overheat. To prevent performance degradation and damage to the
switch, make sure there is clearance at the top and bottom and around the exhaust
vents.
These instructions will explain how to find a proper location for your Modbus Gateways, how
to connect to the network, hook up the power cable, and connect to the SE400 Series.
Verifying Switch Operation
Before installing the device in a rack or on a wall, power on the switch to verify that the switch
passes the power-on self-test (POST). To connect the cabling to the power source see “Power
Supply Installation” on page 20.
At startup (POST), the System LED blinks green, while the remaining LEDs are a solid green.
Once the switch passes POST self-test, the System LED turns green. The other LEDs turn off
and return to their operating status. If the switch fails POST, the System LED switches to an
amber state.
After a successful self-test, power down the switch and disconnect the power cabling.
The switch is now ready for installation on its final location.
