How does stacking work on this switch?

Uses 4 x 1 Gbps SFP ports for uplink and stacking, providing up to 2,560 Gbps bandwidth across stacked units. Features real-time state synchronization, hitless failover, and hot insertion/removal for seamless scalability and zero downtime.

What Layer 2 features are supported?

Includes 802.1s Multiple Spanning Tree, 802.1X authentication, IGMP Snooping v1/v2/v3, MAC-based VLANs, LACP trunk groups, and port security. These ensure loop prevention, secure access, and efficient multicast handling in enterprise networks.

What are the physical dimensions and mounting options?

1U rack-mountable fixed chassis (17.4" W x 14.6" D x 1.7" H) with standard rack ears. Designed for 19-inch racks, it supports external AC power supply via EPS connector for PoE models.

What management interfaces are available?

Out-of-band Ethernet management port, RS-232 console (9600 bps, 8-N-1), SNMP, IEEE 802.1AB LLDP, ANSI TIA-1057 LLDP-MED. Status LEDs indicate port, power, and system status for quick troubleshooting.

What is the operating temperature range?

0°C to 45°C standard, with PoE models derating to 25°C at full load. This suits enterprise wiring closets while ensuring reliability under varying thermal conditions with proper airflow.
