The cord for PowerEdge 6650, Proliant DL580 G2, and other high powered devies.
Almost all servers, desktops, UPSs, and other computing hardware uses an IEC C14 socket (which mates with an IEC C13 plug) (like the ones below).
Larger devices which draw more current, however, use a C20 socket (and C19 plug). They look like an angry slit-eyed C19 plug, they’re also square (see below).
Almost certainly, you’re now thinking the hardware manufacturer hates you. If this is used equipment, the cord is never included, and if it’s new equipment, the cord is usually a C20 to C19 cord - and you likely don’t have a C20 outlet handy.
- If you do have C20 outlets in your PDU or UPS available, you want a (or more likely two) C20 to C19 cord(s) like the one below.
- If you don’t have a C20 outlet available, and your equipment draws less than 15 amps, you likely want either a NEMA 5-15P to C19 or C14 to C19 cord
- If you’re crazy, you can swap out the C20 for C14 sockets. They generally have the same tooling. This is of course wildly out of spec.
- If you’re equipment draws more than 15 amps, and you don’t have C20 outlets handy, you likely want some form of ‘twist-lock’ style NEMA plug (like an L5 or L6 or maybe, but not likely, an L7) to C19 cord.
- If you’re equipment draws more than 15 amps, and you don’t have C20 outlets, and you don’t have NEMA ‘twist-lock’ outlets, then you maybe want a NEMA 5-20R or TT-30 to C19 cord.
- Finally, if you’re equipment draws more than 15 amps, and you don’t have C20 outlets, and you don’t have NEMA ‘twist-lock’ outlets, and you don’t have either of the (barely) normal non-locking NEMA connectors, you likely need an electrician. Either you have odd high-amperage outlets and need new outlets or an adapter or you have no high-amperage outlets and you either need new outlets or a new circuit.
