We have a cabinet of servers and other hardware (switches, firewalls, etc) that all are currently running on 120v. I've confirmed that the power supply for all of our devices support both 120v and 240v and I understand we'll need to get a 240v PDU. My question is, if we switch from 120 to 240, what power cables do I need to purchase that will plug in to the PDU on one end, and into the server power supplies on the other? For reference, we're using mostly Dell Poweredge servers.

For 208 or 240v in the US and Canada the standard configuration:
From wall to PDU - L6-30R or L6-50R
If you have a UPS, it should use the same connectors both in and out.
The PDU may branch to smaller "extension" units using C19/C20 (Female Plug/Male Receptacle).
Whatever connects to the servers and equipment would use standard C13/C14 (Female Plug/ Male Receptacle) at both ends, which is the same connector as the power supply on those devices. You'd use cords like this one to plug in the servers:
