LevelOne Switch de fibra TOR gestionado L3 de 26 puertos, 24x 1/10GbE SFP+, 2x 40/100GbE QSFP28, fuente de alimentación redundante hot-swap

The LevelOne XQS-3126 is a full Gigabit top-of-rack (TOR) managed switch designed for demanding data center and cloud environments. It provides 24x 1/10GbE SFP+ ports and 2x 40/100GbE QSFP28 uplinks, a switching capacity of up to 880 Gbit/s, and a MAC address table of 128000 entries. The switch features a modular design with hot-swappable redundant power supply and supports a range of IEEE networking standards for reliable operation and simplified management.

Advantages

The XQS-3126 delivers wire-speed L2, L3 and L4 forwarding with low latency using high-performance ASICs and multi-core processors, enabling high throughput and scalability. Built-in high-availability features — including redundant power, hot-swappable components, ISSU and graceful restart — minimize downtime. Virtualization support such as Virtual Switch System (VSS) improves link utilization and network efficiency while standard protocols like STP/RSTP/MSTP, VRRP and LACP provide robust redundancy and failover options.

Suitable for

• Top-of-rack deployment in data centers and cloud racks
• High-performance aggregation and leaf switch roles
• Environments requiring low-latency L2/L3/L4 services and large MAC tables
• Redundant network designs with hot-swap power and seamless failover

How to use

Install the LevelOne XQS-3126 in a standard 19-inch rack at the top-of-rack position and connect server or aggregation links to the SFP+ ports and uplinks to the QSFP28 ports. Configure network parameters via the management interface or CLI to enable required L2/L3/L4 features, redundancy protocols and VSS if used. Use the hot-swappable redundant power supply for uninterrupted operation and follow the vendor maintenance procedures for firmware upgrades and hardware replacement.

Recommendations

For optimal performance, deploy the switch in a properly cooled rack environment, use compatible SFP+/QSFP28 transceivers and fiber cabling, and plan VLAN, routing and redundancy topologies in advance. Apply vendor-recommended firmware updates and use ISSU/GR procedures to maintain zero-downtime upgrades.
