Hallittava L2/L3-verkkokytkin Cisco C9300L-48T-4X-E

The Cisco C9300L-48T-4X-E is a managed L2/L3 Gigabit Ethernet access switch designed for enterprise networks. It provides 48 Gigabit RJ-45 ports and four modular 10G uplinks, supporting standard Ethernet switching and routing functions, a MAC address table of typical enterprise size, and industry networking standards for interoperability and reliability.

Advantages

This switch delivers high-density Gigabit access with managed L2/L3 capabilities, compliance with common IEEE networking standards, and a grey metal chassis suitable for rack deployment. It supports full-duplex operation on all ports and offers a platform compatible with Cisco Catalyst features and software, enabling centralized management, segmentation, and advanced traffic controls.

Suitable for

• Enterprise access layer for offices and campus networks
• Wired connectivity for workstations, IP phones, and access points
• Aggregating access traffic to distribution or core switches

Key specifications

• 48 Gigabit Ethernet (10/100/1000) RJ-45 access ports
• 4 modular 10G uplink ports
• Managed L2/L3 switching functions (VLANs, routing, QoS)
• Support for common IEEE standards including 802.1Q VLAN tagging, 802.1D bridging, 802.1x access control, 802.3ad link aggregation
• Full-duplex operation on access ports
• Metal grey chassis suitable for rack mounting

How to use

Install the switch in a standard 19-inch rack or on a flat surface using the supplied mounting hardware. Connect access devices to the 48 RJ-45 ports and uplink one or more 10G modules to aggregation or core switches. Configure basic switch settings, VLANs, port roles, and routing through the Cisco management interface or your network management system. Apply access control and QoS policies as required for traffic prioritization and segmentation.

Recommendations

For reliable operation, place the switch in a climate-controlled equipment room and ensure adequate ventilation. Use consistent VLAN and security policies across access switches and coordinate uplink speeds with connected distribution devices. Use Cisco-recommended software and firmware updates and integrate the switch into your Cisco DNA management workflow for centralized policy, monitoring, and lifecycle management.
