What is the switching performance?

Switching capacity is 176 Gbps full duplex with 132 Mpps forwarding rate, 16K MAC addresses, and 1.5MB packet buffer. Store-and-forward model ensures reliable transmission with low latency under 2.8µs, handling bursts effectively in enterprise networks.

Is it rack-mountable and fanless?

Yes, it's a 1U rack-mountable switch at 1.75 x 17 x 10 inches, weighing 8.33 lbs, with fanless operation for quiet environments. Integrated 60W AC power supply draws max 30.18W, suiting dense rack deployments.

What management features are supported?

Runs Dell Networking OS 6 with 802.1Q VLAN tagging, 802.1W RSTP, 802.1S MSTP, protocol-based VLANs, and 64 LAG groups (8 members per group). Supports up to 512 VLANs and Open Networking for third-party OS compatibility.

What are the environmental specs?

Operates at 32°-113°F (0°-45°C) and 95% non-condensing humidity; storage at -40°-149°F (-40°-65°C) and 85% RH. Energy-efficient design with RoHS compliance ensures reliability in varied conditions without active cooling.

What is the power supply configuration?

Includes one integrated 60W AC power supply with maximum consumption of 30.18 watts. No redundant PSU or PoE support, optimized for low-power, non-PoE access switching in cost-sensitive bulk deployments.
