FAQ
What are the port configurations on the Cisco Nexus 9348GC-FXP?
The switch provides 48 fixed 10/100/1000BASE-T Gigabit Ethernet RJ-45 ports for copper connections, plus six expansion slots: four SFP28 slots for 25 Gigabit Ethernet and two QSFP28 slots for 100 Gigabit Ethernet. These uplink slots support optical fiber or direct-attach copper cables, allowing flexible high-speed connectivity for aggregation or server links.
Does this switch support Power over Ethernet (PoE)?
No, the Nexus 9348GC-FXP does not provide Power over Ethernet capabilities. It is a data-only switch designed for high-density Gigabit Ethernet connectivity with high-speed uplinks, requiring separate power sources for connected devices like IP phones, cameras, or wireless access points.
What Layer 3 routing features are available?
As a Layer 3 managed switch, it supports static routing, OSPF, EIGRP, BGP, and PIM for multicast routing. It also handles inter-VLAN routing, access control lists (ACLs), quality of service (QoS) policies, and IPv4/IPv6 dual-stack operation, enabling scalable network segmentation and traffic management without external routers.
How is power redundancy implemented?
The switch supports two hot-swappable power supplies that can operate in redundant mode. If one power supply fails or is removed for maintenance, the second unit continues to provide full power to the switch, ensuring uninterrupted operation. The power supplies accept a wide voltage range from -48V DC to 230V AC for compatibility with various data center power systems.
What rack mounting options are supported?
The switch is designed for standard 19-inch racks with a 1U form factor. It includes tool-less mounting brackets for quick installation and supports both front-rack and mid-rack placement. The dimensions are 1.72" height, 17.30" width, and 19.70" depth, with front-to-back airflow for proper cooling in enclosed cabinets.
Can I use this switch for fiber optic connections?
Yes, the SFP28 and QSFP28 uplink slots support optical fiber transceivers for both 25 Gigabit and 100 Gigabit Ethernet connections. This allows long-distance fiber runs between switches or to servers, with compatibility for various fiber types and distances depending on the transceiver modules installed.
