@ricci Close enough. I think it might have been a 5509. This an old picture from a lab I ran, and being from around 2002, I don't think I would have had a 6509 to play around with, they were too valuable to us at the time. But I could be wrong.

Another picture of it here. Is that a 6509 or 5509? I can't tell by looking anymore, been awhile since I've touched either.

@jtk @ricci I am voting 5513.

Same amount of fan inlets on the 6509 and the 5513 I believe (same physical size?) but the 5513 was higher density with thinner cards.

Also seems like the supervisor is in the top slot vs the 6509 that required you to install the sup in slot 5/6 (near the bottom)

@jtk @ricci I used to run Cat 5505s and 6509-Es for many years. Honestly the 6509E was probably the most reliable box I ever had the pleasure to use even now.

When the apocalypse happens it’ll be cockroaches and 6509s left.
