On the package is a sticker that shows the configuration, package contents, and some of the specifications.
The server ships in a thick box, and the package is surprisingly smaller than what we expected. The NAS isn't full depth, so it didn't require a massive package to keep it secure.
Inside, we found a well-packaged server with good protection for shipping. The drive rails were in a separate box inside the package.
I prefer two inches of dense foam on all sides, but we didn't get that on the 5400r WSS. The foam on the sides is only around an inch thick, but the box is thicker than most.
Inside, we found four paper manuals and instruction sheets.
The server ships with cage nuts, screws, one Ethernet cable, a power cable, a reusable zip tie, and a USB flash drive and system restore flash-based media.
Rack rails are also included and shouldn't be over looked. Many NAS products ship without rails, and the manufacturer sells them as an add-on. We've never really liked the 'add-on' approach since you can't rack a server without them in a graceful manner, and $150+ seems a bit much for an add-on accessory that is a necessity.
