Cisco Nexus 9300 Managed L2/L3 Gigabit Ethernet-switch 48 poorten PoE

The Cisco Nexus 9300 Managed L2/L3 Gigabit Ethernet Switch with 48 PoE ports is a managed enterprise switch designed for reliable wired connectivity in data centers and corporate networks. It provides 48 Gigabit Ethernet (10/100/1000) RJ-45 ports with Power over Ethernet support and a switching capacity of 256 Gbit/s. The switch supports standard L2 and L3 protocols and a 32,000-entry MAC address table to maintain scalable network performance.

Advantages

This managed switch delivers a high port density with PoE capability, enabling power and data over the same cable for devices such as IP phones and access points. Its support for common Ethernet standards (including IEEE 802.1Q VLANs, 802.1p QoS, 802.1x security, and 802.3ad link aggregation) ensures interoperability and predictable behaviour in mixed vendor environments. The device’s switching capacity and MAC table size support growth and stable forwarding in medium to large deployments.

Suitable for

• Enterprise access layer connecting workstations, wireless access points, and IP phones
• Small to medium data center top-of-rack deployments requiring Gigabit connectivity
• Environments needing PoE/PoE+ to power edge devices

How to use

Install the Cisco Nexus 9300 switch in a standard 19-inch rack using the supplied mounting hardware and connect power according to site electrical requirements. Use the console port or out-of-band management interface to perform initial configuration, enable VLANs, assign IP addresses for management, and configure routing or L2 features as required. Connect endpoints and PoE devices to the RJ-45 ports and verify power allocation and port status via the switch management interface.

Recommendations

Use the switch with an appropriate UPS and adhere to Cisco-recommended cooling and cabling practices. Keep firmware updated and apply configuration backups before major changes. For optimal PoE performance, verify total power budget and plan port power allocation for connected devices.
