2.3 Mounting
The EKI-6528T/TPI supports two mounting methods: DIN-rail & Wall.
2.3.1 Wall mounting
1. Attach the brackets included to the switch with screws.
2. With the brackets attached, hang the switch to nails on the wall.
Figure 2.2 Attaching the Metal Mounting Kit

EKI-6528TI/ 6528TPI User Manual 8
2.3.2 DIN-rail Mounting
1. Align the screw holes between the DIN-rail clip and the unit.
2. Hang the device to the DIN-rail.
3. Hook the device over the DIN rail and let it drop down straight to slide over the
rail smoothly.
Figure 2.3 DIN-rail Installation
2.4 Network Connection
Prepare the M12, 4-pole D-Coded Fast Ethernet Port mating cable for Ethernet con-
nection. The M-12 D-coded Fast Ethernet ports are auto-sensing for 10Base-T or
100Base-TX devices connections. Auto MDI/MDIX means that you can connect to
another switch or workstation without changing straight through or crossover cabling.

3.1 Troubleshooting
3.1.1 Power Input
Verify that you are using the correct power cord/adapter. Don’t use the power adapter
with DC output higher than the rated voltage of the equipment. Or the equipment will
be damaged.
3.1.2 Cable
Select proper cables to construct your network. Please check that you are using the
correct cables.
3.1.3 Diagnosing LED Indicators
Diagnosing LED Indicators: the equipment can be easily monitored through panel
indicators, which describes common problems you may encounter and where you
can find possible solutions to assist in identifying problems.
If the power indicator does not light up when the power cord is plugged in, you may
have a problem with power cord. Then check for loose power connections, power
losses or surges at power outlet. If you still cannot resolve the problem, contact your
local dealer for assistance.
If the LED indicators are normal while the corresponding cables are connected
correctly but the networking is still inactive, please check your system’s Ethernet
devices’ configuration or status.
