September 21, 2009 at 11:38Gigabit Switch Netgear GS504T
Good day.
Since we were talking about modems , I decided to share my old piece of iron.
Once my old friend called me and said that he had some kind of computer-network thing lying around ... said: “Come take a look at what it is, otherwise it’s been in our office for the fifth year now, we don’t know why it is needed, only it collects dust.”
This is a 4-port gigabit switch (switch?), Netgear GS504T, not managed.
The original box, with everything included in the kit: instructions, manufacturer’s warranty, 19 "rack mounts, power cable. Judging by the instructions and the Internet, 2000 release.
About the features and parameters from the instructions:
All ports are operational, honestly holding a 1Gbps connection.
* Red sim card for the device scale
, but there is one thing ... look inside.
The abundance of fans cooling (control?) The microcircuit of each port, and two more cooling the entire case. All this together creates a fairly large noise.
I do not know much about the devices of switches / switches, but the logic suggests such a picture. Immediately after the network connectors are transformers for galvanic isolation with the network (apparently so that there is no potential difference between the devices); chips with the inscription "EtronTech" - RAM, cache memory, 3 for each port; in the center of “Galileo” - roughly speaking percent. What's under the radiators and fans?

In conclusion, a short video clip of the operation of the device, with sound. I understand that this will not be able to convey the whole atmosphere, but still. The first 20 seconds - against the background of noise, only the desktop and laptop create noise, you can hear the clanging of optic motors in the camera ...

Features
The Model GS504T switch has the following key features:
• Four full-duplex copper Gigabit ports with standard RJ-45 connectors
• Automatic address learning function to build the packet-forwarding
information table
The table contains up to 8,000 media access control (MAC) addresses (that is,
the switch can support networks with as many as 8,000 devices).
• Full-duplex mode to double throughput of point-to-point connections by letting
individual ports transmit and receive concurrently when the other end also sup-
ports full-duplex mode
• Wire-speed filtering and forwarding of the traffic with no delay
• Store -and-forward intelligent processing to minimize erroneous packets on the
network
• Easy Plug and Play installation with no software to configure, which saves time
and minimizes the potential for configuration errors
