Block diagram of CSS318-16G-2S+IN

Does anyone have a block diagram for the CSS318-16G-2S+IN? I guess it is a new product… I can guess how it looks like on the inside, from the outside appearance, but I’d like to document my network without assumptions (or block diagrams of switches that I don’ t have).

Thanks!

Well, it is just a switch, based on the 98DX2518, so I guess the block diagram is just a square with 98DX2518 written inside it, and 16+2 ports connected to that.

Block diagrams are useful when there is more than one chip inside, and it is interesting to see interconnecting lanes, but that does not appear to be the case for this device.

Then my earlier impression was wrong, since the G-ports are grouped in two sets of eight.

The sparsely available info indicates the 98DX2518 has: 24x1G + 2x10G + 2x10G Stack

So a switch with 24 ports (instead of the 16 on this one) still with a single chip in it. And more ports when the stacking connections are used.

A block diagram would be useful for a 48-port version, so you can know between which port groups there is a potential bottleneck. But in this switch there is none, just wirespeed between all ports.

You could check out the Netpower 16… Which is listed as the CRS318-16P-2S+. If they use the same chip, then that’s a possibility.

At first I got excited with your post thinking that they had an indoor version of the NP16. Then I saw “SwitchOS” and went back and saw “CSS”…

It is a different switch chip, but the block diagram would likely be very similar.
