Figure 8-34. Direct Connect Configuration with Unduplicated PNC
Each PN in a direct-connect configuration must be connected to the other PNs
through a fiber link. Each PN has one EI that functions as an Archangel. This EI
must be connected with fiber to an EI located in the PN with an IPSI. If an EI is
functioning as an Archangel (bus master), its amber LED will be flashing at a rate
of 2 seconds on and 200 ms off.
