Hardware Troubleshooting 8-1
This chapter explains how to troubleshoot IES-1000 hardware.
8.1 System Startup
When you turn on the IES-1000, it automatically runs a self-test that takes approximately 20 seconds. The SYS
LED will remain on if your IES-1000 has started normally.

STEP CORRECTIVE ACTION
1 With the AC power model, make sure the power cord is properly connecting the IES-1000’s power
socket to an appropriate power outlet. Refer to the Hardware Specifications appendix to make sure
you are using the correct power source.
With the DC power model, make sure the power wires are properly connecting the IES-1000’s power
terminal to an appropriate power supply and the power supply is operating normally. Refer to the
Hardware Specifications appendix to make sure you are using the correct power supply.
2 Make sure the network module is properly installed in the IES-1000 (refer to the Hardware Installation
chapter).
3 With the AC power model, make sure the fuse is not burnt-out. Replace the fuse if it is burnt out (refer
to the Removing and Installing a Fuse appendix).
4 The LED itself or the unit may be faulty; contact your vendor.
8.2 The ALM LED Is On
The ALM (alarm) lights when the IES-1000 is overheated and/or the fans are not working properly and/or voltage
readings are outside the tolerance levels.
Table 8-2 ALM LED Troubleshooting
STEP CORRECTIVE ACTION
1 Make sure you can feel and/or hear the fans working - working fans emit a low buzz and blow air.
If the fans are not working properly, make sure the power connector is connected properly.
Contact your vendor if the fans do not work. Do not remove fans from the IES-1000. Only a qualified
distributor should remove or repair fans.
