Is this a Layer 3 switch and what features does it support?

Yes, it's a managed Layer 3 switch with routing capabilities, QoS for traffic prioritization, ACLs for filtering, and IEEE 802.1X authentication. These enable VLAN segmentation and security without external devices, ideal for enterprise routing at wire speed.

Does it support stacking and uplinks?

Stackable configuration allows multiple units to operate as one via optional 10 Gigabit uplinks. This provides scalable management and high-bandwidth aggregation, with 64,000 MAC addresses and 99.5 Mpps throughput for demanding networks.

What are the memory specifications?

Features 128 MB SDRAM, 16 MB flash, and 4 MB packet buffer (1 MB per 12 ports). This supports large tables and burst handling, ensuring non-blocking performance in high-traffic enterprise environments.

How is the switch managed?

Fully managed via SNMP, command-line interface (CLI), Telnet, and web-based GUI. Status LEDs indicate power, fan, and port activity, with rack-mountable form factor and hot-swappable power supplies for easy deployment.

What form factor and power options are available?

Desktop/rack-mountable in 19-inch EIA racks (1.7" H x 17.3" W x 16.9" D). Includes hot-swappable redundant power supplies and console/auxiliary ports on the rear for reliable, maintainable operations in data centers.
