For ~$40 you won't get anything with a working 10Gb port sadly.
The managed 2810-48G or -24G switch will do the rest of what you want. Note that the 4 cages you see in the pictures are SFP (1G) not SFP+ (10G) ports, and they are shared with the last 4 copper ports.
Avoid the ones without the G at the end - they are 10/100 switches, sometimes with a 1G uplink depending on the model. Basically worthless these days (but they are managed). I have some 24 port ones you could have for cost of shipping.
I have dozens of the "ProCurve J9022A Switch 2810-48G" switches deployed all over, they are great for run of the mill IPv4 networking.
Some notes:
- They can fall apart under massive traffic loads (high PPS) but that is common for that age of switch. Cisco etc have issues too.
- Only supports up to 32vlans, and you have to reboot the switch to change the max # of vlans
- Number of multicast groups supported is low, and varies based on the max # of vlans you configure
- Single internal power supply, you can get a external RPS unit and speedy cables to add redundancy but I have never attempted
- Gawd awful old school java web ui. Don't even both trying to get it to work, use the CLI over the serial port or telnet / ssh
- No IPv6 support to speak of (doesn't matter if just used for L2)
- They have fans. If they fail the switch will probably work still if it is in a cooler environment with airflow. You will get error led's and messages in the console / snmp. Airflow is side to side, no holes in front/back.
Test them out when you buy them used - I have gotten ones in with bad ports (both physical issues and the port just doesn't link up),but that is good idea for all used stuff. I have had individual ports fail on me, but the other ports were fine. Odd that it is single port failures and not groups of nearby ports like I have seen in other switch series in the past.
There is a lot of documentation out there for the series of switches from HP (now on the HPE site), you can figure out all the details be reading through the manuals before buying if you want.
Moving up the price and features stack, the 2900 series switches have one or 2 module slots on the back that offer 10G in the obsolete CX4 format or huge X2 transcievers. You can pick up the optics for $20-50 each and then use a SC to LC jumper to connect to something recent.
If you have other questions ask away!
