Power Application - Harris CM-30 Installation & Operation Manual

3 – Installation & Wiring

3.4 Power Application

After all equipment has been installed and wired, perform these steps to apply power to each shelf:
1. Verify that all modules (common, channel, and power) are seated snugly.
2. If the shelf is AC-powered, plug in the AC line cord. If the ACS-OPT1 dual AC power feed option is
installed, plug in both AC line cords.
3. If the shelf is DC-powered, insert the external power fuse.
4. Verify that the POWER indicator light is on, and the POWER FAIL indicator light is off. In a 3RU
shelf, both the MAIN POWER FAIL and REDUNDANT POWER FAIL indicator lights should be off.
Ignore all other indicator lights on the shelf for the time being. If no lights for any power supply
are on, one of these scenarios has occurred:
• Both power modules have failed.
• Fuses on both power supply circuit boards have blown.
• Most likely, power has not been wired to the shelf.
If the POWER lights turn on, but the POWER FAIL light for one power supply is on as well, that
power module is not functioning or has a blown fuse on its printed circuit board.
Test for the correct voltages.
Note: On a 3RU shelf, if the POWER indicator lights turn on, but the POWER FAIL indicator light for
one power supply is on as well, that power module is not functioning or has a blown fuse on
its printed circuit board.
5. Observe that each CM-30 module displays indicator lights matching its current mode setting after
power is applied.
