Discovering connection of passive cables
First Claim
1. A system capable of discovering connection of passive cables, the system comprising:
- a first subsystem and a second subsystem, connectable to each other via a passive cable, each connected to a high-level management tool, and each including;
a signal driver/receiver capable of sending and receiving data and signals over the passive cable; and
a connection discovery device to access low-level power up/down controls of the signal driver/receiver to, via physical layer communication;
send a local unique identifier (ID) of the particular signal driver/receiver over the passive cable; and
receive, over the passive cable, a remote unique ID of the signal driver/receiver in the other connected subsystem,wherein the connection discovery device is further to send the local unique ID and the remote unique ID to the high-level management tool, andwherein, to compare unique IDs received from the first and second subsystems, the high-level management tool is to;
concatenate the local unique ID and the remote unique ID received from the first subsystem;
flip the local unique ID and the remote unique ID received from the second subsystem and concatenate them; and
compare the concatenated IDs from the first and second subsystems.

Abstract
In one example in accordance with the present disclosure, a system is provided. The system includes a first subsystem and a second subsystem, connectable to each other via a passive cable, and each connected to a high-level management tool. Each subsystem includes a signal driver/receiver capable of sending and receiving data and signals over the passive cable and a connection discovery engine to access low-level power up/down controls of the signal driver/receiver. The connection discovery engine is to, via physical layer communication, send a local unique identifier (ID) of the particular signal driver/receiver over the passive cable. The connection discovery engine is further to, via physical layer communication, receive, over the passive cable, a remote unique ID of the signal driver/receiver in the other connected subsystem. The connection discovery engine is further to send the local unique ID and the remote unique ID to the high-level management tool.

9. A method of discovering connection of passive cables, the method comprising:
-
accessing controls of a signal driver/receiver in a first subsystem, wherein the signal driver/receiver is capable of sending and receiving data and signals over a passive cable to a connected second subsystem; sending a local unique ID of the signal driver/receiver of the first subsystem over the passive cable to the second subsystem; receiving, over the passive cable, a remote unique ID of a signal driver/receiver of the second subsystem, wherein the sending and receiving are performed via physical layer communication using the controls; communicating the local unique ID and the remote unique ID to a high-level management tool, wherein the first and second subsystem are each connected to the high-level management tool; and comparing, by the high-level management tool, unique IDs received from the first and second subsystems, including; concatenating a first unique ID and a second remote unique ID from the first subsystem; flipping a first unique ID and a second unique ID from the second subsystem and concatenating them; and comparing the concatenated IDs from the first and second subsystems. - View Dependent Claims (10, 11, 12, 14)
