Does it support link aggregation?

Yes, it features IEEE 802.3ad Link Aggregation Control Protocol (LACP) for dynamic trunking, plus IEEE 802.3ab Auto MDI/MDI-X on all 10/100/1000-T ports, enabling bandwidth aggregation and redundancy across multiple links.

What management features are available?

Network management includes Find-Fix-and-Inform for automatic detection and repair of common issues, plus dual flash images for independent primary/secondary OS files during upgrades. RS-232C console provides direct access.

Yes, the rack-mountable stackable design uses the open module slot for stacking modules or 10-Gigabit uplinks, allowing expansion to higher port densities in enterprise environments without hot-swapping modules.

What Ethernet standards does it support?

Gigabit Ethernet (10/100/1000Base-T) per IEEE 802.3, 802.3u, 802.3ab standards. Ports duplex: 10/100 half/full, 1000 full-only, with Auto-MDIX for flexible cabling.

What is the form factor?

Rack-mountable stackable switch, ideal for 19-inch racks. Front panel includes port LEDs, mode select, reset/clear buttons, and status LEDs for Test, Fan, RPS, Module.
