FAQs

Q: What does RJ-21X provide compared to individual RJ-45 leads?
A: RJ-21X consolidates many Ethernet pairs in one connector, simplifying high-density switch-to-patch-panel cabling.

Q: Is the pinout T568A or T568B?
A: It follows Cisco’s telco pinout for Catalyst modules; patch panel breakouts typically map to T568B, but verify your panel’s wiring guide.

Q: How many ports does one cable support?
A: It carries up to 25 pairs; effective port count depends on the specific Catalyst 5000 module and panel mapping.
