What is the switching capacity and stacking capability?

The switch offers 160 Gbps switch fabric and 160 Gbps stacking bandwidth, with 40 Gbps per switch dedicated to stacking. It supports closed loop stacking up to 360 Gigabit ports or 384 10/100 ports with 32 Gigabit uplinks, ideal for scalable high-density deployments.

Does it support VLANs and QoS features?

Yes, it supports 4,096 VLAN IDs and extensive QoS including traffic classification, ingress rate limiting, Weighted Round Robin queuing. Additional protocols like IEEE 802.3ad link aggregation, Jumbo Frames (9,216 bytes), and IGMP Snooping v1/v2 enhance segmentation and performance.

What are the power and environmental specs?

Power requirements are 100-240V at 47-63Hz with optional redundant power via C2RPS-PSM and 441 BTU/HR heat dissipation. Operating temperature is 5°C to 40°C (41°F to 104°F), storage -30°C to 73°C, suitable for standard enterprise rack environments.

What is the form factor and weight?

It is 1U rack-mountable with dimensions 44.1 cm x 4.4 cm x 36.85 cm (17.36 x 1.73 x 14.51 in) and weighs 5.05 kg (11.12 lbs) net or 3.47 kg unit only. This compact design fits standard 19-inch racks for space-efficient installations.

What security features are included?

Security includes IEEE 802.1x authentication, SSH, and RADIUS. Combined with extensive VLAN support and policy options, it provides robust edge security for stackable networks in enterprise settings.
