Looking for: Aruba S2500 Mobility Access Switch S2500-48T with 4 10GB ports.

Good afternoon,
   Just wondering if anyone has some old Aruba S2500 switches sitting
around.  I understand these are good for moving some devices to 10GB

I saw them on Ebay, but wanted to check locally first.

=============================================================== From: Dave Brockman ------------------------------------------------------ I don't know which model you are looking at specifically, but it looks=20 like the majority of the S2500 switches only have 10Gb uplink ports (max=20 of 4). If you want real 10Gb connectivity, you can find a=20 N3K-C3064TQ-10GT for under $1,000 on ebay with 2 power supplies. Not=20 sure what Aruba requires in Cloud management these days, but the Cisco=20 unit can be managed locally... With Gratitude, Dave Brockman Senior Network Engineer Gig City Cloud, LLC itches sitting=20 GB=20

=============================================================== From: Lynn Dixon ------------------------------------------------------ I=E2=80=99m currently using three Aruba S2500s and love them. The 10gb port= s can be configured as regular ports with a single command. They work great. The PoE on them is pretty fantastic as well. They=E2=80=99re cheap on eBay, got all= three of mine there. 20 =3D20 0 20 uba S2500 sw=3D o 10=3D

=============================================================== From: Dave Brockman ------------------------------------------------------ uplink ports are just ports, anything special you need to make them run=20 as "regular"? Feel free to unicast if you want to do a deeper dive, I'm=20 not very familiar with Aruba's offerings. HP burnt me too many times in=20 the past. -Dave ports can=20 Bay, got=20 0 =A0 Not=3D20 some old Aruba vices

=============================================================== From: Lynn Dixon ------------------------------------------------------ With Aruba uplinks they will only activate if plugged into an adjoining Aruba out of the box, so those ports can=E2=80=99t be used for anything el= se but uplink to another Aruba. I think Aruba calls them =E2=80=9Cstacking ports= =E2=80=9D. It=E2=80=99s easy to disable stacking https://community.arubanetworks.com/blogs/arunkumar1/2020/10/20/how-to-remo= ve-switch-port-from-stacking-on-aruba-mobility-access-switch With that the ports become regular ports with the full 10gb, not shared like in some gear. I have two in the datacenter and One here at home. Great pieces of gear for the price in the used market. =3D20 =3D20 =3D20 10gb =3D =3D20 p on e=3D =3D3D2=3D C2=3D DA0if anyone has=3D e de=3D

=============================================================== From: Dave Brockman ------------------------------------------------------ Hmmm, looking the spec sheet over, this isn't half shabby.... This is=20 100% manageable local via SSH/HTTPS? Most everyone is using a 4x10Gb=20 breakout on uplink ports these days, the 2.5/5/10Gb days are (hopefully)=20 a slight bump in the past at this point. 8k L3 Routes w/ OSPFv2 support is intriguing, especially with PoE=20 support and I'm seeing < $100 for non PoE on Ebay..... -Dave =20 ything else=20 acking ports=E2=80=9D.=20 remove-switch-port-from-stacking-on-aruba-mobility-access-switch=20 =20 ome.=20 dive, y em. The re pecifically, but it have 10Gb uplink tivity, you can find h 2 power these days, but the t wondering=3D3DC2=3D3DA0if re good for moving cally first.

=============================================================== From: Lynn Dixon ------------------------------------------------------ Yeah, 100% manageable via SSH. The commands are very cisco-like, but not 100%. Its close enough that its very familiar and most cisco folks can understand whats going on with their configs. It does have a HTTP/S interface, but its kind of basic, but workable. I've just been managing them via SSH like a normal cisco switch. The 10gb ports indeed are not shared bus. I've verified this on by saturating all 4 ports bidirectionaly using iperf3 on a bunch of RHEL machines. These things are pretty great for the price you can pick them up for. I wound up winning one on ebay for 90 bucks, the others I paid around 130-150 for, and I've been very happy with them. Just a note, the 10gb ports do not, of course, have PoE, but all the other ports do indeed, and if. memory serves correct, its something like 400 watts total across them all? They easily and happily power all my Unifi gear, and a few PoE voip phones, and some RPi's using PoE dongles.
