What is the switching performance?

Maximum switching capacity is 104 Gbps with 77.4 Mpps forwarding rate, supporting wirespeed on all ports. It handles 8,192 MAC addresses, jumbo frames, and store-and-forward switching. Link aggregation via IEEE 802.3ad LACP boosts bandwidth for uplinks.

How is the switch managed?

Web-managed interface, CLI via console port, SNMP, and HTTPS encryption. Protocols include DHCP relay, ARP (256 entries), NTP, and system log. Supports 32 IP static routes for Layer 3 functionality, plus STP/RSTP/MSTP for loop prevention.

What power requirements does it have?

Internal fixed power supply with IEC 320 inlet, 100-240V AC 50/60Hz input at 1.2A max. Power consumption is 55.4W maximum, dissipating 189.03 BTU/hr. Efficient design suits rack environments with low operational costs.

Does it support VLANs and VoIP?

Yes, supports 256 port-based VLANs (IEEE 802.1Q) with auto-voice VLAN for VoIP prioritization. Includes IEEE 802.1x authentication, ACLs, and QoS. This optimizes delay-sensitive traffic in converged networks.

What are the physical specs and environment ratings?

Rackmount 1U form factor: 17.3 x 10.2 x 1.7 inches, 11.2 lbs (5.08 kg). Operates at 0-45°C (32-113°F) and 10-90% non-condensing humidity. Status LEDs indicate power, link speed, and traffic.
