What is the switching performance?

Provides 128 Gbps full-duplex switching capacity and 95.2 Mpps throughput, with 256 MB SDRAM, 32 MB flash, 4 MB packet buffer. Supports wire-speed IPv4/IPv6 forwarding, IRF2 stacking up to 4 units, and LACP aggregation for up to 14 groups of 8 GE ports.

What are the physical dimensions and mounting options?

Dimensions: 44 x 30 x 4.4 cm (17.3 x 11.8 x 1.7 in), weight 4 kg (8.8 lb). Mounts in EIA-standard 19-inch telco racks or cabinets with included hardware, ideal for 1U data center deployment.

What power options are supported?

Voltage input: AC 100-240 V, 50/60 Hz; DC 10.8-13.2 V. Redundant power supply compatibility ensures high availability in enterprise environments.

Is it suitable for Layer 3 routing?

Yes, as a Layer 2/3 switch, it supports static routes, RIP v1/v2/RIPng, OSPF v1/v2/v3, port/VLAN-based ACLs, 32K MAC addresses, 4K VLANs (port/MAC/protocol/QinQ), and QoS features like CAR and SP+WRR scheduling.

What expansion capabilities does it offer?

Two expansion slots accept modules like 1/2-port 10GE XFP, 2-port 10GE CX4, or 2-port SFP, enabling up to 48 autosensing 10/100/1000 ports total for scalable Gigabit or 10GE uplinks in growing networks.
