About the Cisco WS-4148-RJ Cisco Catalyst 4500 module
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. As genuine Cisco original equipment certified to FCC and CE standards, the WS-4148-RJ ensures compliance and warranty coverage across regulated deployments.
Deployment Scenarios
- Campus network access-layer expansion using existing Catalyst 4500 chassis infrastructure
- Legacy 10/100 workload consolidation in modern switching environments with auto-negotiating duplex
- VLAN-segmented production networks leveraging IEEE 802.1Q tagging across 48 new ports
- Branch or data center access switches requiring field-replaceable, hot-swappable line cards
- Port-authenticated environments using IEEE 802.1X security per connection
