4. Remove the cover of the module to expose the components on the printed wiring
board.
5. Find the Ethernet transformer, which is labeled with either the name Halo or the
name Pulse.
6. Verify that the Ethernet transformer does not show damage that would have
been caused by improper cabling. (You can recognize damage as the top of the

damaged and is ineligible for an RMA.)
7. Connect the power supply to a known good Canopy module via a known good
Ethernet cable.
8. Attempt to power up the known good module and
◦ if the known good module fails to power up, request an RMA for the power
supply.
◦ if the known good module powers up, return to the module that does not power
up.
9. Reconnect the power supply to the failing module.
10. Connect the power supply to a power source.
