Yes, the 3500YL-24G-PWR supports stacking with other 3500yl series switches (24-port and 48-port models) up to 16 units total. Stacked switches operate as a single logical unit with one IP address for management, simplifying configuration and monitoring across multiple switches.

What fiber connectivity options are available?

The switch includes 4 dual-personality ports that support either RJ-45 Gigabit copper or Mini-GBIC fiber transceivers. An open module slot supports optional 4-port 10-GbE expansion. Mini-GBIC transceivers (Gigabit-SX-LC and Gigabit-LX-LC) are ordered separately, enabling flexible fiber uplink configurations.

What is the switching capacity and latency performance?

The switch delivers 101.8 Gbps switching capacity with 75.7 million packets-per-second throughput. Latency is sub-3.7 microseconds at Gigabit speeds and sub-2.1 microseconds at 10 Gbps. This non-blocking architecture ensures consistent performance for real-time applications like VoIP and video streaming.

Does this switch support Layer 3 routing?

Yes, the 3500YL-24G-PWR is a Layer 3 managed switch supporting static IP routing with a 10,000-entry routing table. It enables VLAN routing, link aggregation (802.3ad), and advanced QoS policies. Web-based GUI and CLI management interfaces provide flexible configuration options.

What are the physical dimensions and power requirements?

The switch is 1U rack height (1.73 inches) with dimensions of 15.43" x 17.44" x 1.73" and weighs 2.01 lbs. It requires 100-127 VAC or 200-240 VAC input with maximum current draw of 12A/5.7A respectively. Operating temperature range is 32°F to 104°F (0°C to 40°C).

Is this switch suitable for IP surveillance deployments?

Yes, the integrated PoE on all 20 Gigabit ports powers IP cameras while delivering full Gigabit bandwidth. The 75.7 Mpps throughput and sub-3.7 microsecond latency support multiple concurrent video streams. Stackability enables scaling to support large multi-camera installations across multiple switches.
