$20 100-Base-TX 8 Port Hub (w. built in power supply)

Saw this on gotapex:

It's a $20 100-Base-TX hub.

Well it's actually $30 as shipping (for me) is $10 for ground.

Note: It's not autosensing just straight 100-Base-TX so if you have any 10-Base-T stuff it's useless.

Two nice things about this switch: Sturdy metal case and an INTERNAL powersupply.

One bad thing: FCC Class A

Anyone care to comment on if "FCC Class A" is going to cause a problem in my family room??????

even no brand information.

It's an Allied Telesyn hub, it is NOT A SWITCH as someone mentioned. I have a 24 port 10/100 hub by the same company and am quite happy with it. One thought though, that may or may not apply to this model, I do not know. Mine has a fan for cooling, and honestly, the fan is rather loud. If you are putting it in a basement or something (like me) that doesn't matter. However, it may matter to some.
A nifty feature about this hub is if you stack it with another allied hub that has a 10/100 switch in it (any auto-sense 10/100 hub they make) this 100 only hub will become 10/100.
A nice price for a decent hub, I'd buy one if I didn't allready have more ports than I need.

erickotz,

Can you point me in the direction of (or e-mail me) some guidance as to how I can stack switches/hubs and what exactly this can and can't accomplish? I just bought a 10/100 switched hub with only 4 ports, but I'd like to link it up to additional outlets in my new house. Will this hub solve that problem? Does the lack of switching mean I just can't use more than one outlet on this hub at the same time? Thanks, and sorry for my networking ignorance!

Solah,

When an unswitched hub receives a frame of data, it simply repeats it out all of its ports. So if a frame comes in on port 1 and the other computer/node is on port 3, the frame will go out on port 2, 3, 4, 5, etc... And the way Ethernet works with CSMA/CD, two nodes can't trasmit at the same time. If they do, a collision occurs and they have to stop, wait, and retransmit the data. So no other nodes connected to a hub can trasmit if another is transmitting. If you have 4 computers attached to a hub, those 4 computers are "sharing" the total bandwidth.

With a switched hub (aka switch) receives a frame of data, it looks at the physical address and "switches" the frame to the port it knows that address is on. So if a node on port 1 wants to send to a node on port 3, and a node on port 2 wants to send to a node on port 4, they can both transmit at the same time. It cuts down on collisions (I'm not sure as if there should even BE collisions using switched segments), and each transmission will get the total bandwidth...

I dunno if that was a good explanation or not :-/ Just remember that a hub repeats out all ports and a switch takes it up a layer and looks at an address. It then switches the frame according to an address table its built that tells which port a node is connected to. Cheers!

Oh yeah, as far as stacking hubs and switches... Each hub/switch should have at least one port that is uncrossable? I'm not sure on the exact term there. But anyway, you can connect a regular Cat5 cable do the uncrossed port on one of the devices and then to any other port on the other device. If you don't know/have an uncrossed port, you can make or buy a "Crossover" cable. Which does the crossing internally (in the wire). You can then connect that wire to any of the ports on either device. This cable won't work connecting it from the hub/switch to a computer though... Anyway, hope that answers your question, although maybe I just made it more confusing

Looks good to me!

And I doubt the FCC class will matter, I've not had any hibs/switches (even my cheap ass 8 port 10mbit) cause any problems. And if the fan's loud disable or replace it. Oil could work too.... foam pad..

 

[Zach]

Woah, it looks like it might be discontinued (no info on thier homepage), but Price Watch seems to think it's worth $230+. Scary.. must have been a bad ass hub in it's day? Must not come with the extra stacking and rackmount hardware, if this is the right info.

Well, I wouldn't want to disable the fan on my hub, as it is the air comming out of it is warm, I think it would roast itself rather quickly sans fan. Xtremist, I believe you were trying to say uplink port? Anyway, connecting this to another hub through the uplink port would NOT allow 10/100 operation on all ports. The only way it could work is if it was stacked with another compatable Allied hub using the (included) stacking cable. However, I'm thinking now, and I am not even sure if stacking this with a 10/100 autosense hub would allow this hub to work at 10mbps. Allied made some hubs that were 10/100, but the ports that were at 10 could NOT talk to the 100 ports as there was no internal switch. Stacking this with an allied 10/100 hub with 10/100 switch would allow 10/100 operation on all ports. I have not found the specs on this hub, would this hub be an example of this? In any case, the only hub you would have any chance of stacking this with and making it 10/100 is an allied, even then I'm not sure. Still though, great deal on a 100 only hub.

Sorry Deal checker, I thought the:

buyalliedtelesynnow

In the URL would be enough info.

Me Bad: Allied Telesyn is no where near as common as the netgear and linksys stuff that proliferates their forum.

We use Allied Telesyn almost exclusively for our small stuff here at work and they are great. Rock solid construction (I can stand on my 4 port hub) and good reliability.

I have two of these at work, back when they were $30 each, and they work great, but that 100 thing can be a pain. Oh yeah, the rackmount kit for these is only 15 bucks:

Now, I am buying 3 more of these hubs on thursday, so don't go selling them out.

Xtremist,

Thanks for the info!

 

[uncouth]

good deal, thanks for helping me find a hub!
