George

I had planned to post more about this as I built it, but dealing with a sick cat ate up a lot of my time and enthusiasm so I didn’t.

But lately I have mostly been building this behemoth:

Look at his ‘lil leggies

And feets! (They’re SO solid and heavy)

And terrible lighting his big long legs - 17 inches from floor to top, like the supermodel that he is.

(Ignore that I could no longer photograph him lying on his back because his feet are too weighty to support that - AT-AT’s just aren’t designed to lie on their backs kicking their feet. Who knew?, and that his knees are pointing in the wrong direction here because I lost track of which end was the front in the excitement of playing with the adjustable leg positioning. The white handled tool between his feet is the leg adjustment screwdriver)

Somewhere amongst the hundreds of tiny blue technic pins that hold all those outer facade plates on there are some holes where there shouldn’t be, because I have 2 more pins leftover than I should have. But unless something actually falls off I’m not about to go back through the build to find out where I managed to leave them out.

And onto the ‘body’

Some really nice, neat design work going on here to get the right shaping angle for the body without looking awkward and also being really secure.

The top floor locks down with a simple, if fiddly, bit of design which holds it in place securely without adding bulk.

Jo, Flo, and Ho get to just sit there while the build happens around them. They know better than to ask questions.

Flexible and adjustable neck added.

Not a minifigure useable tunnel unfortunately, but it supports the weight of the ‘head’ while remaining flexible and moveable, which is pretty damn impressive tbh!

Shapely butt too.

Got the engine and the outer structural shaping done. There’s a lot of detail that goes into the engine for something that you can’t access very well once the exterior technic framework fits into place.

Seems like a bit of a shame. Ah well.

There’s a ladder running between the two floors, btw. Just in case you were curious.

Now the head. Well, most of it at least (no side panels yet)

Open it up and there are the people!

It’s a tight space inside, but they can see where they’re going on their little screen.

Now it has side panels and moveable weapons.

Fearsome!

And the outer armour is complete!

Lets lift the flaps (like on a toddler book) and see what’s underneath.

Troopers on patrol. Busy guarding that one E-Web heavy repeating blaster.

And snowspeeders on their storage racks, with the engine on the top floor

Technically you can also open the flap at the other end, but all you see is trooper seating and the end of the (non-functional) tunnel through the neck.

Add on a dangly Luke Skywalker for the authentic ‘AT-AT on Hoth’ experience and this build is almost complete

It just needs its sign

Which doubles up as leg adjustment tool storage.

All I need now is a whole bunch of these:

if I ever decide I want to fill my AT-AT with the full complement of 40 troopers and fill those empty snow speeder racks on the other side

But for now I’ve settled for 3 (on a buy 2 get 1 free deal)

.

This is a HUGE set. 6785 pieces (about 1/5 of that is connector pins), 6kg when complete, and standing 25 inches high (if all the legs are fully straightened out) so it comes with a hefty price tag.

(Well, it does when the store haven’t knocked a couple of hundred pounds off for May 4th and you have a whole lot of store vouchers. Husband only paid £34.99 for it cash wise. Total bargain! :D )

But is it worth it?

Yes. Absolutely worth it, this is an amazingly well designed Lego set with a fantastic amount of attention to detail. I can only imagine the time and effort it must have taken to get this set so accurate to the original in visual terms while also scaling it to fit the 40 troopers it’s supposed to be able to hold as well as having space for cargo and speeders.

The legs being able to support the weight of the build while still being positionable and not losing stability must have been a design nightmare all by itself.

The only real downside is working out where I’m going to keep him now he’s built

.

So why George?

Blame it on a childhood spent watching Looney Tunes cartoons and the message my husband left on my wedding anniversary present.

What can I say? The name stuck. He’s George now.

تجهیزات پسیو شبکه، اجزای حیاتی زیرساخت فیزیکی هر شبکه کامپیوتری هستند. این تجهیزات برخلاف تجهیزات اکتیو (مانند روترها و سوئیچ‌ها) که سیگنال‌ها را پردازش و تقویت می‌کنند، صرفاً وظیفه انتقال و هدایت سیگنال‌ها را بدون تغییر در آنها بر عهده دارند. در این مقاله به بررسی جامع تجهیزات پسیو شبکه، انواع آنها، کاربردها و نکات مهم در انتخاب و استفاده از آنها می‌پردازیم.

تعریف تجهیزات پسیو شبکه:

تجهیزات پسیو شبکه به دسته‌ای از تجهیزات گفته می‌شود که برای انتقال سیگنال‌های الکتریکی یا نوری در شبکه بدون نیاز به منبع تغذیه یا پردازش سیگنال استفاده می‌شوند. این تجهیزات شامل کابل‌ها، کانکتورها، پچ پنل‌ها، رک‌ها و سایر اجزایی هستند که بستری فیزیکی برای ارتباط بین دستگاه‌های شبکه فراهم می‌کنند.

انواع تجهیزات پسیو شبکه:

کابل‌ها (Cables): مهم‌ترین جزء تجهیزات پسیو، کابل‌ها هستند که وظیفه انتقال داده‌ها را بر عهده دارند. انواع مختلفی از کابل‌ها وجود دارد که بر اساس نوع کاربرد و پهنای باند مورد نیاز انتخاب می‌شوند:

کابل‌های زوج به هم تابیده (Twisted-Pair Cables): مانند Cat5e، Cat6، Cat6a و Cat7 که برای شبکه‌های اترنت استفاده می‌شوند.

کابل‌های کواکسیال (Coaxial Cables): که بیشتر در شبکه‌های تلویزیون کابلی و شبکه‌های قدیمی‌تر استفاده می‌شدند.

کابل‌های فیبر نوری (Fiber Optic Cables): که برای انتقال داده‌ها با سرعت بسیار بالا و در مسافت‌های طولانی استفاده می‌شوند.

کانکتورها (Connectors): برای اتصال کابل‌ها به دستگاه‌ها و سایر تجهیزات استفاده می‌شوند. رایج‌ترین کانکتورها عبارتند از:

RJ45: برای کابل‌های زوج به هم تابیده

BNC: برای کابل‌های کواکسیال

LC، SC، ST: برای کابل‌های فیبر نوری

پچ پنل‌ها (Patch Panels): پنل‌هایی هستند که در رک نصب می‌شوند و دارای تعدادی پورت RJ45 یا فیبر نوری هستند. از پچ پنل‌ها برای مدیریت و سازماندهی کابل‌های شبکه و اتصال آنها به سوئیچ‌ها و سایر تجهیزات استفاده می‌شود.

رک‌ها (Racks): محفظه‌های فلزی هستند که برای نگهداری و سازماندهی تجهیزات شبکه مانند سرورها، سوئیچ‌ها، پچ پنل‌ها و سایر تجهیزات استفاده می‌شوند. رک‌ها در اندازه‌های مختلفی وجود دارند و به حفظ نظم و امنیت تجهیزات کمک می‌کنند.

پچ کوردها (Patch Cords): کابل‌های کوتاهی هستند که برای اتصال تجهیزات مختلف به پچ پنل یا سایر دستگاه‌ها استفاده می‌شوند.

کیستون‌ها (Keystones): نوعی کانکتور هستند که در داخل پچ پنل، فیس پلیت یا سوکت دیواری قرار می‌گیرند و محل اتصال کابل شبکه هستند.

فیس پلیت‌ها (Face Plates): قطعاتی پلاستیکی هستند که بر روی دیوار یا رک نصب می‌شوند و محل قرارگیری کیستون‌ها و سوکت‌های شبکه هستند.

داکت‌ها و ترانک‌ها (Ducts and Trunks): کانال‌هایی پلاستیکی یا فلزی هستند که برای عبور و محافظت از کابل‌های شبکه در داخل ساختمان یا بین رک‌ها استفاده می‌شوند.

کاربردهای تجهیزات پسیو شبکه:

تجهیزات پسیو شبکه در تمامی شبکه‌های کامپیوتری، از شبکه‌های خانگی کوچک تا شبکه‌های بزرگ سازمانی، کاربرد دارند. این تجهیزات بستری فیزیکی برای انتقال داده‌ها فراهم می‌کنند و بدون آنها هیچ ارتباطی بین دستگاه‌های شبکه برقرار نخواهد شد.

نکات مهم در انتخاب و استفاده از تجهیزات پسیو شبکه:

کیفیت: استفاده از تجهیزات با کیفیت و استاندارد، عملکرد و پایداری شبکه را تضمین می‌کند.

نوع کابل: انتخاب نوع کابل مناسب بر اساس پهنای باند مورد نیاز و مسافت انتقال، از اهمیت بالایی برخوردار است.

استانداردها: رعایت استانداردهای کابل‌کشی و نصب تجهیزات، از بروز مشکلات احتمالی جلوگیری می‌کند.

مدیریت کابل: مدیریت صحیح کابل‌ها در داخل رک و مسیرهای کابل‌کشی، به بهبود جریان هوا و جلوگیری از گره خوردن و آسیب دیدن کابل‌ها کمک می‌کند.
