Operations Manager: “There’s a beeping sound coming from the server room.” Business Owner: “No worries, it’s the UPS. You’ll see a button that says Mute. Just press the button and it’ll stop.” A full week went by, and then the Ops Manager called me. “Bob, the server is wonky. Can you come take a look at it?” I told her yes, and drove to the client’s office. The server was indeed “wonky.” It didn’t come back online correctly after a power glitch. But wait – what’s this? The Uninterruptible Power Supply (UPS) was displaying an error code: E02. I downloaded the manual to my smartphone to see what the error code meant... E02: Charger Fault – No Charge This explains the power glitch! I talked to the Ops Manager and she told me about the phone conversation with the Owner. I wondered how long the UPS was failing? Well, at least long enough for the Owner to develop a routine of muting the alarm! I installed a replacement UPS the next day. Next, I’ll troubleshoot the old UPS and see if its cost effective to repair it. This particular error message usually occurs when the batteries fail. If the charging circuitry is fine and the batteries test bad, I’ll replace them. Otherwise, I’ll recycle the whole thing. THE LESSON If your UPS starts beeping, don’t just press the mute button – call Tech Support! There’s a reason it beeped, and that reason needs to be analyzed.
