outlet20Descrip is a read-write text field (up to 64 characters) that holds a free-form description an administrator attaches to outlet 20 on the Unity PDU, separate from the short label stored in outlet20Name. Because outlet20Name is typically kept short, this description field gives room for extra context an admin wants documented alongside the outlet, such as recording which rack unit or piece of equipment it was allocated to when the rack was provisioned. For example, an admin might set outlet20Descrip to a longer note recording which rack unit or piece of equipment it was allocated to when the rack was provisioned, so anyone reviewing outlet 20's configuration later understands why it's allocated the way it is.
