Packaging and the Teratrend RS431U
The Teratrend RS431U was delivered to us in a brown cardboard box, which is used for both RS431 models.
Included with the RS431U, we found USB 3.0 and eSATA cables, keys for locking the door, feet (just in case you don't want to rackmount the unit), and all hardware necessary for rackmounting.
Looking over the enclosure, we found the front of the unit was manufactured from black anodized aluminum; the remaining shell is made from steel. In the center of the door, an Allen key locking mechanism keeps the drives safe.
When opening the front drive door, we see each bay has its own LED setup for activity. To the left, we have both the reset, and power buttons. Additionally, each drive tray has a lever mounted above it, for easy removal of the drives.
The back of the unit houses the power receptacle, three fans, eSATA and USB 3.0 ports, and RAID switches.
Internally, the RS431U houses its power supply, with the logic board on the right.
