outlet4Descrip is a read-write text field (up to 64 characters) that holds a free-form description an administrator attaches to outlet 4 on the Unity PDU, separate from the short label stored in outlet4Name. Because outlet4Name is typically kept short, this description field gives room for extra context an admin wants documented alongside the outlet, such as recording that it's part of a redundant A/B power pair for a dual-corded server. For example, an admin might set outlet4Descrip to a longer note recording that it's part of a redundant A/B power pair for a dual-corded server, so anyone reviewing outlet 4's configuration later understands why it's allocated the way it is.
