Installing the Harmony Power System 19
Step 4: Confirm That the Harmony Power System Is
Operational
Monitor the LEDs on the front panel of the Harmony Power System to determine if the
unit is functioning properly.
When power is applied, the LEDs will turn on and off in the following sequence if the
Harmony Power System is working properly:
1. All LEDs turn on for 2 seconds.
2. All LEDs turn off for 2 seconds.
3. The Power LED turns amber while the unit performs the Power On Self Test.
4. The Power LED turns green.
During the Power On Self Test, all Input and Output Ports are disabled.
Once the Power LED turns green, all ports are enabled and the Channel Status LEDs
will operate normally (as described in Chapter 2).
If the Power LED turns red, then the unit failed the Power On Self Test. Try recycling
power to the unit. If the Power LED remains red, contact Proxim Technical Support for
assistance.
