It supports both 10\/100\/1000 and 10GBASE-T server access with 1: 1 uplink-to-downlink oversubscription, making it ideal for mixed or full 10 Gigabit Ethernet environments. The base unit offers eight fixed wire-speed X2 ports and two optional half-card slots, delivering 320 Gbps switching capacity and 250 mpps throughput. Key features include low latency, scalable buffers, hot-swappable power supplies (AC or DC), and a field-replaceable fan tray for optimized uptime.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"eight medium-down--one-whole-NG\"\u003e\n\u003chr class=\"is-hidden-mobile-only\"\u003e\n\u003cp\u003eTargeted for space-constrained environments like branch offices or midmarket cores, the 4900M provides wire-speed Layer 3 switching, burst-handling buffer capacity, and high availability. Its semifixed architecture, combined with Cisco’s TwinGig Converter Module, allows flexible deployment of Gigabit Ethernet today with a seamless path to 10 Gigabit upgrades in the future. Designed for operational efficiency, it includes robust management tools and simplifies network operations at the aggregation and core layers.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003chr\u003e\n\u003cdiv class=\"product-section container jc-between-center is-flex-row\"\u003e\n\u003cdiv class=\"eight medium-down--one-whole-NG\"\u003e\n\u003cb\u003eSecurity\u003c\/b\u003e\n\u003cul class=\"margin-empty\"\u003e\n\u003cli\u003ePort security for MAC address control\u003c\/li\u003e\n\u003cli\u003eAccess Control Lists (ACLs) for traffic filtering\u003c\/li\u003e\n\u003cli\u003eFibre Channel Security Protocol (FC-SP)\u003c\/li\u003e\n\u003cli\u003eVSAN-based access control\u003c\/li\u003e\n\u003cli\u003eZone-based QoS and security enforcement\u003c\/li\u003e\n\u003cli\u003eTraffic isolation using VLANs and PVLANs\u003c\/li\u003e\n\u003cli\u003eDHCP snooping and dynamic ARP inspection\u003c\/li\u003e\n\u003cli\u003eUnicast Reverse Path Forwarding (uRPF)\u003c\/li\u003e\n\u003cli\u003eSecure Shell (SSH) Protocol and SNMPv3\u003c\/li\u003e\n\u003cli\u003eFabric binding for open system security enforcement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"eight medium-down--one-whole-NG\"\u003e\n\u003chr class=\"is-hidden-mobile-only\"\u003e\n\u003cb\u003ePerformance\u003c\/b\u003e\n\u003cul class=\"margin-empty\"\u003e\n\u003cli\u003e320 Gbps switching capacity\u003c\/li\u003e\n\u003cli\u003e250 million packets per second (mpps) forwarding rate\u003c\/li\u003e\n\u003cli\u003eWire-speed performance on all ports\u003c\/li\u003e\n\u003cli\u003eLow-latency architecture optimized for data center environments\u003c\/li\u003e\n\u003cli\u003eScalable packet buffering to handle bursty traffic\u003c\/li\u003e\n\u003cli\u003eJumbo frame support for improved throughput\u003c\/li\u003e\n\u003cli\u003eOptional half-cards for flexible port expansion and traffic scaling\u003c\/li\u003e\n\u003cli\u003eSupport for both 10\/100\/1000 and 10 Gigabit Ethernet\u003c\/li\u003e\n\u003cli\u003e1: 1 uplink-to-downlink oversubscription capability\u003c\/li\u003e\n\u003cli\u003eHigh-availability hardware with redundant power and cooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003chr\u003e\n\u003cdiv class=\"description-title-divider shadow margin-bottom\"\u003eSupported Half Cards\u003c\/div\u003e\n\u003cdiv class=\"product-section container jc-between-center is-flex-row\"\u003e\n\u003cdiv class=\"one-fourth product-section-extras specs  medium-down--one-whole-NG\"\u003e\n\u003cdiv class=\"view-server\"\u003e\n\u003cimg title=\"20-Port Wire-Speed 10\/100\/1000 RJ-45 Half Card\" alt=\"20-Port Wire-Speed 10\/100\/1000 RJ-45 Half Card\" src=\"https:\/\/expresscomputersystems.com\/cdn\/shop\/files\/cat-4900m_card-20p_400x.jpg\" srcset=\"\n        https:\/\/expresscomputersystems.com\/cdn\/shop\/files\/cat-4900m_card-20p_400x.jpg 400w,\n        https:\/\/expresscomputersystems.com\/cdn\/shop\/files\/cat-4900m_card-20p_600x.jpg 600w,\n        https:\/\/expresscomputersystems.com\/cdn\/shop\/files\/cat-4900m_card-20p_900x.jpg 900w,\n    \" sizes=\"(min-width: 900px) 322px, (min-width: 408px) 100vw\" loading=\"lazy\" width=\"322\" height=\"327\" style=\"width: 100%;
