@jkwon: It turns out that I was mistaken, the red cross you're referring to, i.e. cross over a connection, means that one or more Electrical Rule check has been suppressed for said connection. You can read more about it [here](techdocs.altium.com/.../Sch_Obj-NoERC((No ERC))_AD

If so, does not the exteranl crystal oscillator(X1) in the pca10028 work?

The meaning is the same, i.e. it's not connected to VDD.

Yes, it is the schematics of PCA10028.

Which schematic is this? It looks like it is from one of our nRF51 or nRF52 DKs?

Sorry, my question was very abstractive. I add some pictures with green arrow. What does it mean? Unlike 'x' in the picture you add, the lines in the picture I add are linked.

If you're referring to the red x markings in our Reference Circuitry Schematics, see below, then as @RK correctly points out they mean N.C , i.e. No Connection.

Which schematic? Can you give .. some details? Usually a red X in a schematic means no connection.
