outlet3Descrip is a read-write text field (up to 64 characters) that holds a free-form description an administrator attaches to outlet 3 on the Unity PDU, separate from the short label stored in outlet3Name. Because outlet3Name is typically kept short, this description field gives room for extra context an admin wants documented alongside the outlet, such as noting a maintenance restriction, such as being reserved for hot-swap testing. For example, an admin might set outlet3Descrip to a longer note noting a maintenance restriction, such as being reserved for hot-swap testing, so anyone reviewing outlet 3's configuration later understands why it's allocated the way it is.
