What is true of it

D♭7sus4 is D♭, G♭, A♭ and C♭ — 1, 4, 5 and b7 counted from D♭.

On an instrument that cannot reach all 4, the 5 goes first, in that order.

The easiest of the 5 fingerings below is x44404: 4 fingers, held at the 4th fret.

None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.

2 of the 5 need a barre.

1 string stays silent.

The brass dots are D♭, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
