Cisco WS-X6148-RJ21: Catalyst 6500 48-port 10/100 line card, RJ-21 Telco, voice-upgradable.

The Cisco WS-X6148-RJ21 is a Catalyst 6500-series 48-port 10/100 line card with RJ-21 (Telco) connectors, upgradable to inline power for VoIP handsets. The RJ-21 connector groups multiple ports behind a single high-density 25-pair Telco connector rather than 48 individual RJ-45 sockets, which suits patch-panel-style cabling in dense wiring closets and data centres.

The card’s inline-power-upgradable design meant a site could deploy it initially for data-only access and add the power daughter card later to support IP phones, without needing a different line card for voice-capable ports. Catalyst 6500 chassis fitted with cards of this generation remain in service on many established campus and enterprise networks. Tech-Star is UK-based, ships worldwide and can confirm compatibility with your specific chassis and supervisor engine on request.
