Fast replacement paths are critical for accessories deployed in production networks—and the Cisco WS-4148-RJ delivers the field-replaceable reliability enterprise teams depend on. This 48-port Fast Ethernet line card slots directly into the Cisco Catalyst 4500 series switching platform, adding IEEE 802.3 and IEEE 802.3u standards-compliant connectivity across your network fabric. With 48 RJ-45 copper ports delivering 10/100 Mbps per port on auto-negotiating half- or full-duplex links, the WS-4148-RJ bridges legacy infrastructure and modern workload demands without requiring supervisor engine replacement.
Network engineers and IT procurement teams selecting line cards for Catalyst 4500 deployments will find the WS-4148-RJ (manufacturer part number WS-4148-RJ) compatible with Catalyst 4500 series chassis including the 4503, 4506, 4507R, and 4510R. The module integrates seamlessly with Catalyst 4500 supervisor engines via IOS-based management and supports IEEE 802.1Q VLAN tagging and IEEE 802.1X port-based authentication for segmentation and access control. Hot-swap capability means planned expansions and field repairs happen without downtime. Inline power compatibility with capable supervisor engines enables powered device support where needed.
