=========================

The label on the cable indicates two parts: “M91A-01:01” and “U61A-01:09”. The first part of the label “M91A” refers to a specific type of equipment as per the exhibit. According to the exhibit, “M9” corresponds to “MDS 9xxx”, which is a Cisco Multilayer Director Switch. The second part of the label, “U61A”, does not directly match any category in the provided list; however, it seems to be an internal reference that could be related to user-specific configurations or locations.

Since we are looking for the target equipment type and not where it was mistakenly connected, we focus on the first part of the cable label. The numbers following “M91A” indicate slot and port information. Therefore, based on this labeling system and referring to the exhibit provided, which lists various EMC and Cisco equipment types along with their corresponding codes (like AP for APIC Appliance or CN for Cust. Network), we can deduce that “M91A” stands for “MDS 9xxx”. The subsequent numbers “-01:01” suggest Slot 1, Port 1.
