What is the switching capacity and performance?

The switch provides 32 Gbps maximum switching capacity and 23.7 Mpps forwarding rate with store-and-forward, non-blocking wirespeed across all ports. It supports jumbo frames up to 9K bytes and handles up to 8,192 MAC addresses.

Does it support VLANs and security features?

Yes, it supports up to 256 IEEE 802.1Q VLANs, port security, MAC/IP-based ACLs, IEEE 802.1X authentication, and LACP link aggregation with 4 trunks max. IGMP snooping and port mirroring are also included for traffic control.

Is it suitable for VoIP deployments?

Yes, auto-voice VLAN automatically assigns VoIP traffic to a dedicated VLAN. It offers 8 traffic queues per port with IEEE 802.1p prioritization and DSCP support to optimize delay-sensitive voice traffic on Gigabit ports.

What are the physical dimensions and power requirements?

Dimensions are 44 x 440 x 173 mm (1.73 x 17.3 x 6.81 in), 1 RU rack-mountable, weighing 2.0 kg (4.4 lb). Uses external power supply with 100-240 VAC input, 50/60 Hz, max 198 BTU/hr dissipation.

What compliance standards does it meet?

Emissions: EN 55022 Class A, FCC Part 15 Class A, CISPR22 Class A; Immunity: EN 55024, EN 61000-3-2/3-3. Supports IEEE standards like 802.1Q, 802.1X, 802.3ab/z, ensuring reliable operation in enterprise environments.
