A good way to quickly check whether or not the FRD-4 communication circuit is functional is to check voltage on one of the output cables to cool plate units. \u00a0The output cables connect to the right-most ports on the FRD-4. Each of them has a red wire and black wire that carry 5V DC power. \u00a0Backprobe one of these connectors while it is connected to a live FRD-4 to verify the 5V power. \u00a0If there is no voltage, the communication logic on-board the FRD-4 has suffered critical failure. \u00a0Contact GetSpares.com<\/a> for replacement or repair solutions.<\/p>\n","protected":false},"excerpt":{"rendered":"
