Configuring a Dell PowerConnect 28xx Switch

I recently came into possession of a pair of PowerConnect 2824 switches. These are 24 port gigabit switches that support either managed or unmanaged use, jumbo frames, up to 64 VLANs and up to 4 Link Aggregation Groups. In spite of all their excellent functionality, they’re quite cheap, too, costing under $300 last I looked.
The pair I was given were both configured for unmanaged use. This means that they act as layer 2 only switches. Port multipliers, if you will. I wanted to specify some VLANs and use the jumbo frames feature for my iSCSI configuration. To that end, I needed to configure these switches to be managed.
However, the manual is down right lacking in information about how to do this. I called Dell tech support and got the instructions on how to change these switches to managed mode and I’m putting the instructions here so that you don’t have to call support:
1) Connect a machine to the switch.
2) Configure the connected NIC on said machine to use an IP address in the 192.168.2.0/24 subnet. E.g., 192.168.2.105.
3) Press the “managed” button on the front of the switch for 10 seconds. This is a pinhole button so ensure you have a paperclip or the like ready for this step.
4) Upon releasing the button, the “Managed” light should turn on.
5) Fire up a web browser and navigate to http://192.168.2.1. This should connect you to the switch’s management interface.
6) Enter the username as “admin”. Leave the password blank.
7) On the next screen, don’t change anything; just click “OK” or “Apply” or whatever it is.
8) The switch will reboot and it will now be ready to configure as a managed switch!
I tested this on a PowerConnect 2824. However, as Dell’s documentation for this switch covers everything in the 28xx series, I imagine these instructions should work for any switch in the series.
