Off the top of my head... 1. motherboard batteries may be going/gone, leading to BIOS changes when unplugged during the move (or shut down for any extended period of time), leading to failures. 2. iffy wiring connections of any type (cards, data cables, power supply cables, jumpers from case to motherboard, etc.) > > Personally I suspect some type of hardware issue (this equipment is about 5 > years old), but one of my co-workers isn't so sure hardware is in play.

If moving involves any "rolling on small wheels over rough surfaces" failed electrical connections are a common result. We have a cart with about 10" inflated tires which is used to move equipment, specifically to minimize this issue. The last 2 racks we moved were completely disassembled, the frame moved first, then the nodes moved to it on this cart.
