how to install Cisco Catalyst 9300 24-Port Fixed PoE+
Installing the Cisco Catalyst 9300 24-Port Fixed PoE+ switch begins with selecting an appropriate deployment scenario and ensuring power, cooling, and rack space are sufficient. Begin by mounting the unit in a standard 19-inch rack and securing it with the included hardware. Connect the switch to a stable power source and verify power-on self-test (POST) indicators. Once powered, plan your topology to leverage the four 1G uplinks by connecting them to your distribution layer or to a core switch in a modular campus design. It is recommended to label PoE ports and assign VLANs to ensure security and segmentation from day one.
Next, estimate your PoE device density to confirm that the PoE budget aligns with your deployment. PoE+ ports can power a range of devices such as IP phones, wireless access points, and network cameras. If you anticipate high device density or high-powered endpoints, consider enabling features like energy management to optimize PoE usage and reduce waste. After physical wiring, perform initial software configuration. This involves setting up basic device credentials, enabling appropriate VLANs, configuring trunk and access ports, and applying QoS policies to ensure reliable voice and video performance across the network.
Software configuration can be performed via the console, SSH, or through a centralized management platform such as Cisco DNA Center. Begin with secure administrative access, then implement core policies for security, segmentation, and device onboarding. For IoT and mobile devices, apply appropriate access control lists (ACLs) and dynamic VLAN assignment to minimize risk and improve user experience. Finally, test connectivity across all endpoints and verify PoE functionality by powering up a sample device on a PoE-enabled port. Document the configuration and maintain a baseline to simplify future upgrades or troubleshooting. With routine maintenance and firmware updates, the Catalyst 9300 remains a resilient, scalable backbone for growing networks.
For ongoing management, leverage Cisco DNA Center or compatible network management tools to monitor port utilization, uptime, PoE power consumption, and overall health. Regularly review security advisories, update firmware, and refine policies to maintain a secure, high-performance network that meets evolving business needs. The Catalyst 9300’s ability to integrate with cloud management platforms ensures you can extend visibility and control beyond the traditional data center, maximizing uptime and accelerating service delivery across campus locations.

I think this book will give many beginners a good quick start into Python programming
A review of "Python: QuickStart Guide by Robert Oliver"
Published by ClydeBank Media
Copyright (c) 2023
ISBN-13: 978-1-63610-038-8
First Edition: Last Updated: April 24, 2023
In summary - I feel this book has missed some opportunities, is trying to be “cute" and is somewhat lacking in detail in some of the beginning explanations. However … this book starts at the bottom and builds you up. When you are done … while not quite a Python Expert you will be well on the way. It really is a good overview of Python and covers a lot of ground; while it does leave out some things I would have liked to see, [cough cough turtle graphics — turtles make a great introduction to objects … even if they may have taken a detour to the application you end up with at the end] you can’t put every everything including the kitchen sink in a book like this.
Most of the things I would have liked to see differently are just nit-picky: they have these little icons (Note, quckclip, detour, etc.) … things like that should be DEFINED before they show up — the introduction is the perfect place to do that; that that isn’t done bugs me. That he brings up “X” as in Algebra isn’t really needed, programming variables are known quantities for the most part, and are more like the names for things, or the name of a box that contains something … the “variables” in Python has little to do with the variables in Algebra which are unknowns you are trying to solve for.
As example of missing “essential” detail: In the discussion of data types such as integers, and floating point numbers, and strings but don’t discuss magnitude and precision for the numerical datatypes. Not everyone needs to know that in integers basically have as much precision as you have allowed it memory to run. This isn’t “normal” in most other languages and is a nifty feature of Python. I have used it to compute really large numbers such as the 1 millionth Fibonacci number, or the 33rd perfect number (it has over half a million digits, and is very simple in Python[see the short code at the end of this review for another example]). It doesn’t discuss comparison operators for objects you create (I feel that is an important topic, but may be more advanced that this introductory book is designed for - and actually isn't NEEDED but would have been a nice thing to mention). On the other hand the discussion of Python data structures really was very clear.
While it does discuss and use objects, the discussion really isn’t in-depth. But that is OK as this is a quick start guide, not an in-depth reference book. You could (and will later if you go on) find enough to fill a book half this size talking about the details of Python Object Oriented programming ([P]OOP).
This one may not be a nit if they are older: The format is somewhat difficult to read when it comes to the code examples. Code examples are highlighted in gray, this lowers the contrast and unless well lighted makes it harder to read, so make sure you read it in a well lit room or use a book light. Bolding the highlighted text would probably solve this issue. The binding is great (it is spiral bound) and even being somewhat thick, every page lies flat — this makes it easy to use for when you are copying the code examples to your computer. The code can be downloaded, but I would recommend that you type everything in. Errors made by having your typed code not be what you intended to type in are a common source of errors and learning how to find and correct those sorts of errors now will save you a lot of problems.
The book isn’t just introductory material, but gets into some fairly advanced topics such as databases, test driven development, and using GIT. The book does do a good job about more “advanced” topics. It talks about some features of Python while just a few years old may not have been know to some older Python Developers (like dataclass, or Lamda expressions). It provides you an introduction to developing websites, and interacting with the web, multiprocessing, optimization, and error handling to name a few. I really think topics that may stump some people the author has explained clearly and concisely the make the topics easy to grasp.
One thing that surprised me is that it didn’t talk about the philosophy of Python in the introduction…
No braces {} or semicolons, but you do need the occasional colon
Whitespace, indentation, and blank lines MATTER in Python. That needs to be hammered in (really).
One simple way of doing things (not a lot of different ways to do the same thing).
And the name Python comes from the Monty Flying Circus kind and not the Reptile kind (even though a lot of Python “stuff” has the snake kind on it).
It doesn’t talk about Python 2. Python 2 and 3 are different Code bases, They eventually stopped “improving” Python 2 and Python 3 is the one true version of Python, it should at least have a mention.
The phylosophy is important because in Python white space in really important, and that is part of the philosophy of Python that should be covered. This is probably one of the things that messes people up most in the beginning (and that case matters — cow and COW are not the same, as they are in a lot of cases in Windows machines).
Here is an example of case mattering: (not from the book).
>>> cow=3
>>> cow==COW
Traceback (most recent call last):
File "", line 1, in
NameError: name 'COW' is not defined. Did you mean: 'cow'?
Here are some things to try once you get your Python installed that show a bit of Python Humor…(also not from the book)…

The Zen of Python, by Tim Peters
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!

Python is a fun programming language to learn and it probably the best language for a beginner. Python is a fairly easy to learn programming language, and Mr. Oliver’s brief look back at BASIC is fitting. I do think that Python, in may ways, really is the new BASIC.
In conclusion: This book does provide you a step by step learning path, if followed will get you a lot more knowledgeable about Python, while fairly wide it isn’t always as deep as I would like. The Python QuickStart Guide(r) is like one of those tour packages, it covers all the things you need to see but sometimes you wish you could linger a bit more on a topic. The Coffee Shop game that you work in throughout most of the book is interesting and leads to some good topics and gets you in to some really good practices so you start out right.
The author has provided a video the help you get going which will help you over the rough beginning spots. If you take the time, and follow the book step by step, I think you will be pleased with your progress, and will be able to do some fun stuff quickly. Just remember to do a little bit every day, because learning to program is like learning any language — practice makes perfect.
PS: You might want to try this to see just how easy it is in Python to work with large integers:
f=1
for x in range (1, 101):
f=f * x
print (f" {x:>3d}! = {f:>210,d}")
print
If you had the book, you would know what to do with that!
Also - It may not show up but the following lines need to be indented two spaces in the above example
f=f * x
print (f" {x:>3d}! = {f:>210,d}")
print

Great intro to (Monty) Python...
Format: Hardcover
Quick start books are really really good. Get right to the topic but in a way that does not leave your head swimming. Great intro text to the language that will prepare the reader for deeper tomes with the added bonus of a pretty well structured intro project. Recommend this publisher and will be looking for more of their titles.

Great for reluctant readers
Format: Paperback
This book is great for reluctant readers. I got this for my niece and her mother asked if I knew of any other graphic novels like this one because of how much my niece loved reading it. I ended up reading it and the story is very enjoyable and inspiring. The art is exceptional. I was very happy to find that there are more in the series. I bought both the first and second ones for my step daughter and other nieces this Christmas. Highly recommend!

Foster Care! Magic Paint! Superheroes! OH MY!
Format: Kindle
This was a great read. I loved everything about it. The artwork is vivid. The main character’s personality is spot-on. The humor was great.
Ashley is a girl in a world where she is herself and nobody else. At least, that’s what she thinks. Really, she’s a girl stuck in foster care because her dad’s in jail. She has a carefree attitude on the outside, but on the inside she’s really tender-hearted. Then one day a new family shows up, attempting foster care with Ashley. She’s living pretty nicely there and she’s made a friend named Luke. Then one day her foster mom comes home acting kind of strange. Later, Ashley decides to snoop into what’s in that mysterious suitcase her foster mom brought in and hid in a closet. She and Luke find paint. Lots of tubes of paint. Ashley puts them on her skin, because she “likes the texture.” This is where I think it’s waaaaay too obvious that what she’s doing has to be specifically made like that for the storyline. It’s okay though, they do an okay job of hiding it. Anyway. These paints are magic paints that give the person who wears them superpowers! So of course Ashley has to go and use them and be a superhero she calls ‘Primer’. But her foster mom’s job wants those paints she brought home back. So they send their roughest, toughest soldier to retrieve them. Ashley, of course, has a fight with her foster mom about it, and Ashley decides to run away, taking the paints with her.
Then obviously the soldier dude shows up, with a bunch of robots. There it just turns into your normal superhero fight scene, but then Ashley loses and the paints are taken except the teleportation one. The soldier, by the way, is named Strack. So then Ashley’s like, “Oh no, I’ll neeever be a hero” even though obviously she will, this is a superhero story. Suddenly her phone is ringing. It’s her foster dad and mom. She picks up their video call and it’s STRACK! He’s adult-napped her foster parents, of course. She debates going to fight Strack, or to just leave it. She goes with leave it until she looks up and sees a painting she made and this suddenly gives her confidence, for reasons unknown.
So then there’s another big fight scene with Strack, but Ashley is overconfident like she knows she can’t die, it’s a book and that would be devastating for little ones reading it. Anyway, she wins and frees her parents and they all live happily ever after.
So, this story ends in a cliffhanger that’s not a very good one. It’s just Ashley’s REAL dad seeing her on TV from when she went out and was a superhero the first time, and he’s like, “You’re not Primer, every father knows his daughter’s eyes, ASHLEY. See you soon.” So if I was hanging from a cliff here, I would be attached to it with a safety cable and I would be laying on the top of the cliff, with only my foot hanging off. It’s not much of a cliffhanger.
This was a great book about a female superhero. Oh, and another thing I forgot to mention, there is a page you should skip if you are reading to a child under seven. Page…. Let’s see here… oh yes. Page seventy-seven. It involves a gun and likely shooting afterwards, but it isn’t shown. I am a very sensitive person, and even I, an almost-teen was kind of rustled by it. Anyways, great story, lovely artwork, good book.
I’m rounding up from 4.5 stars.
