2.1. Installation Guidelines
The following guidelines are provided to optimize the device performance. Review the
guidelines 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 2.
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 and 10/100/1000 fixed port devices, the cable length from the switch to con-
nected 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 degredation and dam-
age to the switch, make sure there is clerance at the top and bottom and around the
exhaust vents.
2.1.1 Connecting Hardware
In this instruction, it will explain how to find a proper location for your Modbus Gateways,
and how to connect to the network, hock up the power cable, and connect to the EKI-5000
Series.
2.2. 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 43.
At startup (POST), the System LED blinks green, while the remaining LEDs are a solidy
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.
