This my 24th post and my last for my internship requirements. I have officially graduated from the 2 year CNET program at Bellingham Technical College (BTC).. It’s been a long journey, but I managed to do well despite the stress and staying up late at night. This is my first degree from a college and I am proud that I did it. I am also grateful for all the help I received at school (I will never forget everyone that helped) and at home (my wife Bliss) and all my friends.
23rd day of my internship
When having difficulty pulling cable through a flexible tube use lubricant. It was so much easier.
The new office is getting its cubicles setup.
It’s not easy to slide the partitions into all of these little tabs.
Connecting the electrical receptacles.
Closer look at the electrical plugs.
There is progress.
22nd day of my internship
Today is bring your broken laptop in day. Below is a ToughBook laptop that a cliet complained after he did an Windows XP update it stopped working.
Here is a cool feature unique to the ToughBook.
After looking at the event viewer I see many log errors.
I decided to revert back to a previous state.
After reverting back. Problem solved. Now we need to educate the client not to do any more updates. Since Microsoft stopped supporting Windows XP there are no more new updates available.
The next laptop comes from a local firehouse which they said the “T” key is not working.
I removed the keyboard by removing this strip and two screws. Next slide the keyboard up.
Take a look closer toward the top and middle. Sorry the picture is blurry. You should see a orange capacitor next to the one on the left.I looks like to me a short circuit.
This is on the back of the keyboard. You can see more synging.
After diagnosing this laptop I am sad to say the laptop needs to retire. Before I recycle it I need to remove the HDD and install it into another laptop.
21st day of my internship
Today was a site visit at a local hotel to install a Ubiquiti network, a high-performance routing and advanced security WiFi network. The UniFi Security Gateway that extends the reach of the UniFi Enterprise System to route, secure and manage the network for optimal performance and reliability from the convenience of any device connected to the internet. Since cables were already installed by the owner, all we had to do was install 9 access points, 1 managed switch, and gateway/firewall.
Here are examples of 2 of the access points were are going to install today.
Here is the switch we are going to install.
Before going to the site, we configured the EdgeSwitch 24 port managed PoE+ gigabit switch with 2 VLANs. The corporation VLAN will be configured with an IP range of 10.11.15 – 254 /24 and the guest VLAN with the IP range of 192.168.6- 254 /24. The 24v PoE+ will power the 9 access points and the Cloud key, a fully integrated, stand-alone UniFi controller hardware remote. This tiny device allows you to manage this network from any computer, tablet or smart phone that has internet access.
Now, everything has been configured and functioning as needed. Time to go to the hotel and install all of this.
This is the hotel’s network closet located in the laundry room screwed into the wall. Not the best location and not very tidy.
Here is after the new switch has been installed.
Next is out with the 9 old access points and in with the new.
20th day of my internship
This is a Dell Inspiron 660s Desktop, a super small Windows 7 desktop that is about 10 inches tall. It was brought in because the client is complaining it intermittently shuts down by itself especially at night. Some of the online forums indicate it could be a software or hardware issue. One forum stated it may be a incompatibility with certain Adobe downloads. What we decided to do is do was do a clean Windows 7 Pro installation including all new Dell drivers and Windows updates onto a new HDD.
Windows 7 Professional edition installed
Driver and Windows updates are being installed
Here is a cool tool to that we used that is pictured below. It’s a Ethernet to USB adapter that has the ability to connect to the internet without any network drivers on the computer. This device will save me time so I don’t have to download the network drivers onto a flash drive and then upload it on the newly installed computer.
I included a video that describes the adapter in detail.
At the end of the day this computer it was returned to the client without any symptoms of shutting down. If the computer shuts down unexpectedly again the plan is to order a new computer.
19th day of my internship
Here is the giant of all computers. It’s a Cooler Master CM Stacker
Look at the size of this monster! 22.8 x 9.8 x 23.8 in
This server has 5 HDDs, 2 optical drives, and a 3.5in floppy drive and it sits on casters for you to push around.
It weighs almost 30 lbs!
It was brought in to diagnosis the problem. The client says it stopped working after he did updates. Well, I believe it’s more serious than that. It can’t boot up.
I believe it’s time to do a clean re-installation of Windows Server 2011. That’s right 2011. Who uses 2011? People at home or small businesses did. If they wanted to store daily backups of all network PCs then this is one way to do it. This device was commonly used before the Cloud was popular. Other uses are:
Streaming of media files across your network
Remote, online access to files and home-based PCs
Extendable with add-ins and third-party apps
- Easy, centralized PC maintenance and secure access to files across your home network
Another problem with this machine has two optical drives that did not physically work. So, to re-install Windows 2011 we used an external DVD drive.
The installation continues….
Everything was working great after installing the important drivers and updates.
During the installation process I found a link to someone’s modification of one of these machines.
18th day of my internship
To complete the Raspberry Pi project we need to configure it to auto boot into the iceweasel browser and then auto-direct it to a Google Doc webpage.
The picture below is a script to boot iceweasel and the Google Docs.
Then you change directories and configure LSDE-pi.
Open up LSDE-pi and enter @iceweasel at the end of the script
Set the Raspberry Pi to auto login.
Bam! It works.
17th day of my internship
This morning I continued with the Raspberry Pi project. I left off with the NOOBS being installed. It installed successfully and now you can see I have a Raspberry Pi graphical (GUI) desktop. The following pictures is the boot sequence.
Finally, a successful operating Raspberry Pi. Now, to turn this tiny device into a digital sign that rotates pictures from the client’s Google Docs folder (website). All the device has to do is display the photos in the doc folder and rotate through them. After it is complete the client can change the photos at anytime while the Raspberry Pi continues to do its job. The picture below is an attempt to try to do that.Sorry for the fuzzy picture.
After my failed attempt, I was notified the electrical inspector is scheduled for this coming Wednesday. He’s going to inspect the new office’s electrical system which includes our network cables. So, we need to hurry up and finish pulling the rest of the cables, attach the cables to the wall ports and neaten up the wires so, they don’t look messy. I must admit, I am getting plenty of exercise going up and down ladders and lifting them. Even though I am tired, I am having lots of fun.
Add a plate here. Did you notice the new paint?
Add a plate here
Add a plate here. Do you like the color? It’s called Shadow.
Here I need to put in a 4 port plate. However, the blue cables are going to continue through while the white cables will be plugged into the ports.
Here is an example of a messy cable. For some reason someone was using a Bayonet Neill–Concelman (BNC) connector. I took care of it by removing it.
Another example of cables that needed to be cleaned up. Rolled up cables are not allowed.
This big pile of cable is our twelve cable waiting for the pole to hide them in to arrive.
16th day of my internship
This is the 3rd day pulling cable. By the end of today, we completed pulling cables inside each wall of the 4 offices and pulled 16 more to the other end of the office which includes 6 cables to the 3 work benches and 10 for something I don’t remember. Here is a diagram of the network that is currently configured.
Before I started pulling cables, I continued working on the Raspberry Pi issues. It was very helpful to diagnose some of these issues by having a known working Raspberry Pi. Having a second one I could swap parts and figure out what’s working and what’s not. For example the mini SD card that came with the Raspberry Pi was defective. By plugging it into the known good device I was able to know for sure the mini SD card was defective. The picture below is the defective mini SD card that I didn’t want to mix up with the good one so, I marked it with a pen. I hope to return it for a working mini SD card.
The good mini SD card I had also had a problem being 100% full, as you saw from my previous post. I discovered it had 2 partitions. That’s why it read 3.8GB. I simply deleted the 2nd partition and now I have 7.7GB. Yay!
After I deleted the 2nd partition there was disk space available. Now I can format it. To format it I have to put the mini SD card into a card reader. Then insert it into my laptop which it conveniently has a card read port on the side .
Installing SDFormatter so I can format the mini SD card.
Now I can format using SDFormatter.Below is the setup window.
Now installing the New Out Of The Box Software (NOOBS). NOOBS is the way to setup a Raspberry Pi for the first time
Installing NOOBS in progress.
Splash screen you will see while it installs.
Another splash screen.
Here is a YouTube video that I used that will illustrate how to install NOOBS using several OS.
more progress to show later….
15th day of my internship
Today was going to be another cable pulling day, but the painters started painting. So we cancelled for today. The contractor said they needed 2 or 3 full days to paint and let it dry.
What I did instead was help set up a Raspberry Pi so it can be used as a digital sign at a local real estate company. However, setting it up was not going as planned.
At first, it did not display anything on the monitor. We tested connections, cables and all of them were good. On the CMD line I typed in sudo apt-get update and for some reason went into a GUI logon window instead of the blank screen.
There were several user accounts already loaded on it and the only one we were able to log in was the guest session.
One reason why I believe we could only log onto the guest session and not the others was the storage device (SD) was 100% full. As it seemed to be full.
However, here is a question. As you can see in the picture above it only thinks it has 3.8GB total capacity. The SD card has 8GB. So, why is it doing this?
My best guess at this time will be to reformat and reinstall Raspbian operating system (OS) and New Out of Box Software (NOOBS). NOOBS tells it to boot the OS. Here is a link that will give you some guidance how to install the OS.
