    Hi, TheBloke,
    To answer your question, I haven't hooked up the tach for the left fan (opposite the power supply), but I'm getting correct PWM control, reporting of fan status, and temperature with the Arctic F8 fans (33C intake, 36C idle exhaust at fan speed 3 - see below).

    SSH@10g-sw1(config)#show chassis
    Power supply 1 not present
    Power supply 2 (NA - NA - Regular) present, status ok

    fan 1 failed
    Fan 2 ok, speed (manual): 1<->2<->[[3]]
    Fan 3 ok, speed (manual): 1<->2<->[[3]]

    Fan controlled temperature: 36.0 deg-C

    Fan speed switching temperature thresholds:
    Speed 1: NM<----->30 deg-C
    Speed 2: 25<----->40 deg-C
    Speed 3: 35<----->90 deg-C (shutdown)


    Exhaust Side Temperature Readings:
    Current temperature : 36.0 deg-C
    Warning level.......: 80.0 deg-C
    Shutdown level......: 90.0 deg-C
    Intake Side Temperature Readings:
    Current temperature : 33.0 deg-C
    Boot Prom MAC: 00e0.52c1.ec8b
    SSH@10g-sw1(config)#


    Here's some ballpark measurements after 30 minutes idle at each speed 1-3 (updated after repeating testing).

    Fan Speed 1: 36C intake, 40C exhaust
    Fan Speed 2: 36C intake, 38C exhaust
    Fan Speed 3: 33C intake, 36C exhaust

    I've got most of the design worked out, and I'm 3D printing the fan assembly in PETG via 3DHubs for about $30 - should be here by the weekend to test. I ended up making the fan shroud reversible (vertically) to allow more flexibility in my rack space.

    Hmm, yeah I used a similar offer and also use some DAC and SFP cards on my computers...

    But it's not what my question is about.
    Especially when you have a piece of equipment with a 10G RJ45 port, not SFP.

    It needs a 10G RJ45(base-T) port on your switch to interface, hence a SFP+ transciever base-T.

    So did someone test some of those ?

    I know I'm a little late here, but the cheapest thing that fits these requirements is a Dell 8024. It's essentially an LB6M (same ASIC) but with a newer faster management CPU and firmware that supports full ipv6 routing

    Hi,

    I already found S5800-8TF12S switch for this purpose.

    I am having a serious problem. Please do not laugh at me. I configured the switch but forgot to write the mem. Now for some reason nothing happens when i plug in the console cable and try to connect. My other switch it works right away when I plug in the console cable.

    what do you mean you forgot to write the mem? do you mean run the "write memory" command? if so, that does not affect the switch booting and outputting data over the serial console port. Are you using the serial console port? did you try to flash or update the switch?

    I'm trying to connect via the serial port and won't connect. Screen stays blank.

    what did you do before this happened? did you try to flash the switch or upgrade its software?
