outlet13Descrip is a read-write text field (up to 64 characters) that holds a free-form description an administrator attaches to outlet 13 on the Unity PDU, separate from the short label stored in outlet13Name. Because outlet13Name is typically kept short, this description field gives room for extra context an admin wants documented alongside the outlet, such as documenting which circuit or PDU feed it draws from. For example, an admin might set outlet13Descrip to a longer note documenting which circuit or PDU feed it draws from, so anyone reviewing outlet 13's configuration later understands why it's allocated the way it is.
