Hi All -- Reporting back as I got things to work.  Thought it would be helpful to record in case others are in the same position I was.I purchased two (relatively cheap) adapters: My Mac has only USB-C ports,but I already had some USB-C to USB-A adapters.  No drivers were needed for anything, it all worked out of the box.Step 1:  Plug the USB to DB9 adaptor into your mac.  Step 2:  On my mac, in the terminal, you can find the cable by running:  ls /dev/tty.usb*You'll see something listed like /dev/tty.usbserial-14420.  (Your numbers may be different.)  If you can't figure out which it is, unplug the cable, look in /dev.  Then replug the cable in and look in /dev.  The new entry will be the thing you're looking for.Step 3:  (Not sure if this is necessary, but I did it.)  Setup things to match the parameters of the switch.  The switch console says that it needs 9600 baud rate, 8 bit data format, 1 stop bit, no parity bits.  I set that with the command:  stty 9600 cs8 -cstopb -parenb .  (You can read the stty man page for explanation of those.)Step 4: Now connect everything together, but don't plug in the powercord on the switch yet.  Run:  screen /dev/tty.usbserial-14420 (substituting in whatever the correct /dev/tty.usb* is for you.)  Then plug in the powercord on the switch.  You now should be connected to the console and see the switch start up.  You're good to go!    (BTW: to end the screen session on your mac you have to hit ctrl+a then ctrl+\ .)There are then instructions here: [URL] .  Don’t skip the step of using a paperclip to  push the "mode" button on the front of the switch to change it to managed mode after erasing the flash file.  After doing that the switch rebooted and then I could get access to the setup wizard, the web gui, etc.   Without doing that it doesn’t work!   I found this video helpful:  [URL] .
Hi Everyone— I recently bought a used PowerConnect 2824 switch. I can power it up and connect to the web interface, but I don’t know the log in username and password. (And no, the defaults of ‘admin’ with no password did not work.) So I’m trying to figure out how to get access to my switch in order to use it. Most of the other posts and websites I’ve found say to connect via a null modem cable to the Console port on the back. The problem is that I have neither a null modem cable nor a serial port on my computer! (And haven’t used serial ports since the late 90s! Flashbacks!) In particular, I have a mac with USB-C ports only (although I do have USB-C to -A adapters and USB-C to Ethernet adapters.) So I’m looking for advice on:1) Is there another way to reset the thing? 2) If I have to buy a cable to get access, what’s the best way to do it? I have found some DB9 to USB ([URL] and DB9 to Ethernet adapters ([URL] Will they work? I’m loathe to buy a cable and wait to get it only to find out it doesn’t work. Or do I need to get one of those AND a null modem adapter? Any help is appreciated.Thanks!
