1. A loopback connector for a system comprising at least one system component having at least one component connector and at least one cable interconnect having at least one cable connector, the loopback connector comprising:
- a connector arrangement configured to be connectable simultaneously to both of the component connector and the cable connector; and
loopback logic for simulating cable interconnect functionality when the connector arrangement is connected to the component connector and for simulating system component functionality when the connector arrangement is connected to the cable connector;
wherein the loopback connector is selectively configured to operate as a loopback connector for both a chassis connector and a cable connector as well as to provide pass-through connectivity between the cable and the chassis connectors.

Abstract
A loopback connector for a system can include a connector arrangement connectable to connector of a system component and/or a cable. The loopback connector can include loopback logic for simulating cable and/or system component functionality. In an example implementation the loopback connector can also operate to protect a system component and/or cable connector during shipping.

11. A system comprising at least two subsystems interconnected via cables, the cables comprising connectors connectable to field replaceable units (FRU) in the subsystems, wherein the system is operable automatically to check the mechanical connectivity formed by the cables independently of whether all system components are fully operational, wherein at least a connector for at least a cable includes a loopback connector, the loopback connector comprising:
-
a connector arrangement configured to be connectable simultaneously to both the cable and a connector for a FRU in one of the subsystems; and loopback logic for simulating cable interconnect functionality when the connector arrangement is connected to the FRU and for simulating system component functionality when the connector arrangement is not connected to the FRU; wherein the loopback connector is selectively configured to operate as a loopback connector for both the connector for the FRU and the connector for the cable as well as to provide pass-through connectivity between the cable and the connector for the FRU. - View Dependent Claims (12)

13. A method comprising connecting a loopback connector to at least one of a component connector of a system component and a cable connector of a cable and performing at least one loopback test, wherein the loopback connector comprises:
-
a connector arrangement configured to be connectable simultaneously to both of said component connector and said cable connector; and loopback logic for simulating cable interconnect functionality when the connector arrangement is connected to the component connector and for simulating system component functionality when the connector arrangement is connected to the cable connector; wherein the loopback connector is selectively configured to operate as a loopback connector for both a chassis connector and a cable connector as well as to provide pass-through connectivity between the cable and the chassis connectors. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
