Three weeks ago, I tooted about getting a new gateway/route/firewall for the home lab. After many fantastic suggestions, I settled on a Atom-based solution in a 1U case. It’s the “Qotom 5X 2.5G LAN 2 SFP+ Barebone Mini Router Q20322G9 with C3558 1U Rackmount Mini Server” as sold on Amazon and shipped from China. The unit arrived 8 days after ordering. It could have been 7. It was out for delivery yesterday, but […]

Eaton 5PX removes power every 24 hours

When I powered on my UPS yesterday, I predicted when it would power off: 24 hours later. To be clear, it’s removing power from the outlets and not sending any notifications to the hosts that it’s about to do so. Today, I captured the console when resetting and trying to power on the UPS. The reset This is the reset output: At this point, I waited. With no more output for 3+ minutes,

Let’s find the dead cell in my Eaton 5PX

Todays goals: pull both the ups and the external battery unit (EBU). While there, swap them so the UPS is on top. Take photos of the wiring. Disconnect each battery. Measure it. Replace anything not like the others. Expecting 13V or so on most. One should read way less. Maybe. But the UPS is now charged to 100% All cells in the UPS measure about 13.4V. Next, the EBU. All aboutt 13.4 or

Complete network shutdown – wtf?

This afternoon, I was running an Ansible script to update the snmpd configuration settings on nagios03 (which replaced nagios02 – which was intentionally destroyed earlier today). After the script completed, I could not access the ngaios3 website, nor could I ssh into the host. My first thoughts: I must have messed up the ssh configuration, I’ll fix it through the console. I can’t get to anything. Anywhere. WIFI now? No, it’s me that’s

Eaton 5PX console booting screen shots

This post shows my screenshots from the console of my Eaton 5PX as it was powered on. In this post: Eaton 5PX 2200 I was trying to clear the Replace Battery warning on my UPS after recently replacing the batteries. At present, the warning message has been cleared, I’m not sure how or why. Before taking these screen shots, the server connected to the UPS was not loading up the driver. This was

Playing around with a ‘failing’ drive

In zpool replace, you can read about a drive which was giving errors and which I replaced. At present, that drive is [still] giving these errors, but it not part of any spool.

Dell R730 – moving disks from front drive bay to PCI slots in r730-03

I’ve been seeing these types of errors for about 4 weeks now. I ordered a replacement drive. When it arrived, I realized I had no free drive bays. When a drive is still functional, I prefer to leave it in the host to retain zpool integrity. Instead, I will add the new drive in, run the zpool replace command, and when completed, remove the faulty drive. I decided to order more Icy Dock

Eaton 5PX UPS – clear the ‘Replace Battery’ warning

Three weeks ago, I wrote about Replacing batteries Eaton 5PX – 5PX2200RT & 5PXEBM48RT.

Optimizing UPS power use when the power goes out

This post is mostly for myself. I’m just putting my Sunday morning thoughts down for later review and consideration. When Selecting replacements batteries for my Eaton 5PX UPS (5PX2200RT & 5PXEBM48RT), I began to think about: when the power goes off, why can’t I keep using my laptop? Usually, I still have an Internet connection: the ISP isn’t going offline. Why not turn off the two servers in the basement, and anything else
